Abstract:

Given the great importance of Ascia monuste orseis as insect-pest of Brassicaceae, this work was carried out to evaluate, under laboratory conditions, the action of botanical insecticides on larvae and egg masses, as well as the food consumption of larvae and test, in field conditions, the efficiency of control, of botanical insecticides which showed better results in laboratory tests, on larvae of A. monuste orseis in kale plants (Brassica oleracea L. var. acephala DC). In laboratory tests were evaluated, at a temperature of 25 ± 2ºC, relative humidity of 60 ± 10% and photophase of 14 hours, the effects of aqueous extracts of 10% w/v of tobacco powder (Nicotiana tabacum L.), of leaves of Melia azedarach L., Eucalyptus tereticornis Sm., Cedrella fissilis Vell. and Trichilia claussenii C. DC., of leaves and twigs of Ateleia glazioveana Baill and Ruta graveolens L., as well as DalNeem®, commercial product based on ripe fruits of neem (Azadirachta indica A. Juss) at 1, 5 and 10% v/v. After being offered discs of kale leaves treated with different treatments to larvae of three days of age, the mortality, the viability of the larval stage and food consumption were evaluated. Also the action of the extracts on egg masses was tested. From topical applications of the extracts on larvae of three days the effect of contact was evaluated through observation of the viability and duration of the larval stage, pupal viability and weight of pupae, and the number of adults with defect. Finally, in experiment conducted in the field, the efficiency of control of products that had better performance on tests in laboratory (tobacco powder, DalNeem to 1% and M. azedarach), compared with the standard treatment, product-based deltamethrin (Decis 25 EC) was estimated. It was found that, in laboratory, the tobacco powder was the treatment that best showed ovicidal activity; after ingestion of the extracts tested, the tobacco powder, followed by DalNeem were better in relation to mortality caused to the larvae; DalNeem, tobacco powder and M. azedarach affected their viability; the contact of DalNeem and tobacco powder caused total mortality of larvae and extracts of M. azedarach resulted in little more than half of viable pupae, presenting a tendency to reduce the weight of pupae and causing malformation in the wings of all adults emerged; both by ingestion and contact action, the extracts tested practically did not change the duration of the larval stage and all the extracts caused fagodeterrente effect on A. monuste orseis. To control A. monuste orseis in Brassicaceae crop, it is recommended the commercial product DalNeem to 1%, respecting the product specifications, since the tobacco powder, in the field, causes dark pigmentation on kale plants.
Devido à grande importância de Ascia monuste orseis como inseto-praga de brassicáceas, este trabalho foi desenvolvido com o objetivo de avaliar, em condições de laboratório, a ação de inseticidas botânicos sobre lagartas e posturas, além do consumo alimentar de lagartas, bem como testar, em condições de campo, a eficiência de controle, dos inseticidas botânicos que apresentaram melhores resultados nos testes em laboratório, sobre lagartas de A. monuste orseis em cultivo de couve (Brassica oleracea L. var. acephala DC). Nos testes em laboratório foram avaliados, à temperatura de 25±2ºC, umidade relativa de 60±10% e fotofase de 14 horas, os efeitos dos extratos aquosos a 10% p/v de pó-de-fumo (Nicotiana tabacum L.), de folhas de Melia azedarach L., Eucalyptus tereticornis Sm., Cedrella fissilis Vell. e Trichilia claussenii C. DC., de folhas e ramos de Ateleia glazioveana Baill e Ruta graveolens L., além de DalNeem®, produto comercial à base de frutos maduros de nim (Azadirachta indica A. Juss) a 1, 5 e 10% v/v. Após serem oferecidos discos de folhas de couve tratados com os diferentes tratamentos, a lagartas com três dias de idade, foi avaliada a mortalidade, a viabilidade da fase larval e o consumo alimentar. Foi testada, também, a ação dos extratos sobre posturas. A partir de aplicações tópicas dos extratos sobre lagartas de três dias, foi avaliada a ação de contato dos mesmos através da observação da viabilidade e da duração da fase larval, da viabilidade pupal e do peso das pupas, além do número de adultos com defeito. Finalmente, em ensaio realizado no campo, foi estimada a eficiência de controle dos produtos que melhor desempenho tiveram nos testes em laboratório (pó-de-fumo, DalNeem a 1% e M. azedarach), comparados com tratamento padrão, produto à base de deltametrina (Decis 25 CE). Verificou-se que, em laboratório, o pó-de-fumo foi o extrato que apresentou melhor atividade ovicida; após ingestão dos extratos testados, destacou-se o pó-de-fumo, seguido de DalNeem, em relação à mortalidade causada a lagartas, além do DalNeem, pó-de-fumo e M. azedarach afetarem a viabilidade das mesmas; sob ação de contato, DalNeem e pó-de-fumo ocasionaram total mortalidade às lagartas e o extrato de M. azedarach destacou-se por resultar em pouco mais da metade de pupas viáveis, por apresentar uma tendência na diminuição do peso das pupas e por ocasionar malformação nas asas da totalidade de adutos emergidos; tanto sob ação de ingestão como de contato, os extratos testados praticamente não acarretaram alteração na duração da fase larval e todos os extratos ocasionaram efeito fagodeterrente sobre o curuquerê-da-couve. Para o controle de A. monuste orseis em cultivos de brassicáceas, recomenda-se o produto comercial DalNeem a 1%, respeitando-se as especificações do produto, já que o pó-de-fumo, no campo, ocasiona pigmentação escura em plantas de couve.

Resumo: Inimigos naturais podem ser importantes na determinação da abundância de populações de insetos. Em lepidópteros, sabe-se que predadores de diferentes tipos agem em todos os estágios de seu ciclo de vida. Neste estudo a intensidade da predação natural por diferentes categorias de predadores sobre larvas e pupas da borboleta Eurema albula (pieridae) foi avaliada experimentalmente e através de observações de história natural, na Reserva Florestal de Linhares, ES. A sobrevivência de larvas em indivíduos pequenos de sua planta hospedeira Senna pendula (Caesalpinaceae) foi significativamente maior do que em indivíduos grandes. No experimento principal gaiolas de exclusão com diferentes malhas e barreiras pegajosas de resina foram utilizadas para restringir de forma seletiva o acesso de diferentes grupos de predadores a plantas contendo larvas jovens de E. albula. Diferentes categorias de predadores generalistas predaram larvas de E. albula e taxas diárias de mortalidade da ordem de 3,3 a 11 % foram detectadas para as diferentes categorias estudadas. Não houve variação espacial nas taxas de mortalidade. Trinta pupas foram distribuídas em três habitats (interior da mata, borda de mata e mussununga) para quantificação e comparação das taxas de predação. A intensidade da predação sobre pupas não diferiu entre os habitats, e a taxa média de mortalidade foi de 12% ao dia. Paralelamente aos experimentos, o número de espécies de diferentes grupos de predadores foi quantificado através de observação e coleta de indivíduos diretamente sobre as, plantas (formigas e aranhas), uso de iscas atrativas e censos (formigas e vespas) e observação direta e uso de redes de neblina (aves insetívoras). Foram identificadas 11 espécies de formigas, 7 espécies de vespas, 12 espécies de aranhas e 21 espécies de aves potencialmente predadoras de ;E. albula na área
Abstract: Natural enemies may play an important role in determining the abundance of insect populations. Butterflies are attacked by different kinds of predators in all stages of their life cycle. In this study the intensity of attack by different groups of predators on larvae and pupae of the butterfly Eurema albula (pieridae) was investigated both experimentally and by means of field observations in the Reserva Florestal de Linhares, ES. The survivorship of larvae feeding on large versus small plants of Senna pendula (Caesalpinaceae) was found to be higher for larvae feeding on small plants. The main experiment consisted of using exclusion cages with different meshes and sticky barriers to selectively restrict the access of different groups of predators to plants bearing E. albula larvae. Plants without cages and sticky barriers were used as controls, making it possible to calculate the reduction in death due to removing one or another source of predation. The exclusion cages and sticky barriers were removable and rotating treatments among sample units allowed control for individual differences among plants. Different groups of generalist predators preyed upon larvae of E. albula and daily mortality rates around 3,3 to 11% were attributed to each predator category (birds, wasps and ants). No spatial variability in mortality rates was detected. Thirty pupae of E. albula were distributed in each of three habitats (inside forest, forest edge and scrub vegetation) and the rates of attack compared. The intensity of predation on pupae did not differ among habitats, I and the mean daily mortality rate was 12%. At the time ofthe experiments the number of species in each predator category was estimated through direct counts on plants (ants and spiders), censusing at baits (ants and wasps), and field observations and mist-net capturing (insetivorous birds). Potential predators of E. albula included 11 species of ants, 7 wasps, 12 spiders and 21 birds

The kale (Brassica oleracea var. Acephala), is an important vegetable among the hardwoods, which is attacked by many pests, especially the cabbage leafworm Ascia monuste orseis (Godart, 1818) (Lepidoptera: Pieridae), whose damage occurring directly in the consumption product. Vegetables like cabbage, are important sources of income for family farming in Brazil and can be cultivated in a traditional way or through organic production thus the objective of this study was to evaluate the effects of pesticides used in organic production system on the A. monuste orseis. For this, we used the commercial products Azamax, DalNeem and Dipel, beyond grout sulfur and Bordeaux mixture at recommended concentrations by the manufacturer carrying out tests as the insecticidal activity. The applications were made in cabbage leaf sections (4 × 5 cm) with sprayer. For assessing the effect of treatments on the development of caterpillars offered the leaf sections to first instar larvae for 24 h, after which the larvae were fed leaf sections for free treatment. To check the action of neem-based products on A. monuste orseis in different instars were offered cabbage leaf sections 24 h to sprayed caterpillars of the first, second, third, fourth and fifth instar. A test was also performed to assess the systemic effects of neem on the insect, therefore, kale plant water stress presented received two irrigations, with products based on neem leaves were cut and offered to the caterpillars that received treated leaves throughout the development. In all trials were assessed daily, mortality, duration of instars, total duration of larval, pupal weight male and female pupal with four days of age, duration and pupal viability observing the percentage of adult emergence. Products Azamax, DalNeem and Dipel showed 100% mortality of the first instar, however the grout caused little influence on the development of A. monuste orseis. When tested in different instars Products Azamax, DalNeem presented mortality in all instars tested, and for Azamax did not observe significant difference in mortality between instars, referring to TL 50 and TL 80 is observed that there is increase in time according the age of the oldest caterpillar tracks which require more time to achieve the desired mortality. When applied to soil the product Azamax, presented higher translocation capacity of the plant causing higher mortality, and prolong the larval stage and pupal derail
A couve manteiga (Brassica oleracea var. acephala), é uma importante olerícola dentre as folhosas, que sofre o ataque de várias pragas, destacando-se o curuquerê da couve, Ascia monuste orseis (Godart, 1818) (Lepidoptera: Pieridae), cujos danos ocorrem diretamente no produto de consumo. Hortaliças como a couve, são de importantes fontes de renda para agricultura familiar no Brasil, podendo ser cultivada de maneira tradicional ou através da produção orgânica, sendo assim, o objetivo deste trabalho foi avaliar a ação de produtos fitossanitários utilizados no sistema de produção orgânico sobre A. monuste orseis. Para tanto, foram utilizados os produtos comerciais Azamax, DalNeem e Dipel, além das caldas sulfocálcica e bordalesa, nas concentrações recomendadas pelo fabricante realizando-se testes quanto a atividade inseticida. As aplicações foram realizadas em secções foliares de couve (4 × 5 cm) com pulverizador manual. Para avaliação da ação dos tratamentos no desenvolvimento das lagartas ofereceu-se as secções foliares à lagartas de primeiro ínstar por 24 h, após este período as lagartas foram alimentadas por secções foliares isentas de tratamento. Para verificar a ação dos produtos à base de nim sobre A. monuste orseis nos diferentes ínstares, foram oferecidas secções foliares de couve pulverizadas por 24 h para lagartas de primeiro, segundo, terceiro, quarto e quinto ínstar. Foi também realizado ensaio para avaliar do efeito sistêmico do nim sobre o inseto, para tanto, plantas de couve apresentado estresse hídrico receberam duas irrigações, com os produtos à base de nim e as folhas foram cortadas oferecidas as lagartas, que receberam folhas tratadas durante todo o desenvolvimento. Em todos os ensaios foram avaliados diariamente, mortalidade, duração dos ínstares, duração total da fase larval, peso de pupa macho e pupa fêmea com quatro dias de idade, duração e viabilidade de pupa observando-se a porcentagem de emergência dos adultos. Os produtos Azamax, DalNeem e Dipel, apresentaram 100% de mortalidade de lagartas de primeiro ínstar, no entanto as caldas causaram baixa influência sobre o desenvolvimento de A. monuste orseis. Quando testados nos diferentes ínstares os produtos Azamax e DalNeem apresentaram mortalidade em todos os ínstares testados, sendo que para Azamax não observou-se diferença significativa na mortalidade entre os ínstares, referente ao TL 50 e TL 80 observa-se que há aumento do tempo de acordo com a idade da lagarta onde lagartas mais velhas necessitam de maior tempo para alcançar a mortalidade desejada. Quando aplicados via solo o produto Azamax, presentou maior capacidade de translocação na planta causando maior mortalidade, além de prolongar a fase larval e inviabilizar as pupas

Abstract:

A agregação em insetos centra-se nas vantagens relativas ao forrageio e no aumento da defesa contra predadores. Além disso, agregações de ovos podem beneficiar-se pelo aumento nas taxas de eclosão larval. Neste trabalho, foram testadas as hipóteses de que agregações de Ascia monuste orseis (Godart, 1819) (Lepidoptera: Pieridae) uma espécie que se alimenta em agregações larvais em plantas da família Brassicaceae - conferem benefícios à performance larval e adulta, na assimilação de alimento pelas larvas, na viabilidade dos ovos e na proteção larval contra inimigos naturais. A possibilidade de um dado comportamento do grupo resultar em maior ataque por inimigos naturais também foi avaliada, bem como um padrão comportamental defensivo em resposta aos inimigos naturais. Para tanto, quatro tratamentos de diferentes tamanhos de agregações larvais foram formados (1, 7, 15 e 30 larvas) para avaliar a performance e a assimilação de alimento em laboratório. Em campo, três tratamentos foram formados (1, 10 e 50 larvas) para testar o efeito do tamanho do tamanho do grupo na predação e parasitismo. A performance do estágio de ovo foi examinada em posturas de tamanhos variados em casa de vegetação. Larvas gregárias desenvolveram-se mais rápido nos ínstares iniciais e tornaram-se fêmeas mais fecundas em comparação às solitárias; entretanto, larvas solitárias apresentaram maior tamanho do que as gregárias. A sobrevivência não diferiu entre os tratamentos em laboratório. Foi observado um menor consumo per capita de alimento por larvas gregárias, sem custos para a assimilação de alimento. A viabilidade dos ovos aumentou com o tamanho da agregação de ovos, comprovando o benefício da agregação larval na fase de ovo. A menor predação per capita em agregações larvais maiores conferiu uma maior proteção às larvas de A. monuste orseis contra predadores e parasitoides, através do efeito da diluição do ataque entre os indivíduos do grupo. O parasitoidismo foi mais expressivo em larvas de primeiros ínstares, enquanto que larvas mais tardias foram mais atacadas por predadores, independente do tamanho da agregação. Por fim, eventos comportamentais que envolvem movimentação da cabeça como exploração e alimentação foram mais perigosos para as larvas de A. monuste orseis em comparação ao repouso e deslocamento, semelhantemente a espécies de hábito solitário. Eventos comportamentais supostamente defensivos foram observados em todos os ínstares e tratamentos. As vantagens da agregação em A. monuste orseis mostraram-se especialmente importantes no estágio de ovo e primeiros ínstares, pela diminuição da mortalidade de ovos e vulnerabilidade larval aos inimigos naturais. Esses benefícios provavelmente sobrepõem-se aos custos, como a competição por interferência observada entre as larvas no final do desenvolvimento. Nossos resultados mostram que o malogro dos ovos e os efeitos dos inimigos naturais constituem fortes pressões seletivas na manutenção da agregação de ovos e larval em A. monuste orseis, a qual confere uma melhor performance do ponto de vista bi-trófico, bem como maior probabilidade de sobrevivência individual sob o ponto de vista tri-trófico.
In insects, the gregarious habit has been shown to improve foraging and defense against predation to both larval and adult stages. Egg clusters could also be beneficial through increased larval hatching. In this study, we tested the hypothesis that egg clusters and larval aggregations of the neotropical butterfly Ascia monuste orseis (Godart, 1819) (Pieridae) - a subspecies that uses Brassicaceae as hosts - lead to several benefits from both bi- and tri-trophic perspectives. Larval and adult performances, food assimilation by the larvae, egg viability, as well as protection against natural enemies were assessed from individuals reared either isolated or aggregated. The behavior of larval aggregations was also examined with respect to predation risk, as well as the corresponding larval defensive behaviors after enemy attack. Four treatments with different larval aggregation sizes were assigned (1, 7, 15 e 30 larvae) to assess larval performance and food utilization in the laboratory. In the field, three treatments were assigned (1, 10 e 50 larvae) to evaluate the effects of group size on predation and parasitoidism. Egg performance was examined through egg clusters of different sizes in a greenhouse. Gregarious larvae developed faster, especially in early instars, and became more fecund females than solitary larvae; however, the latter attained larger body size than the former. Under laboratory conditions, survival did not differ among treatments. Lower food ingestion per capita was observed in gregarious larvae, with no cost in food assimilation. The viability of eggs increased as egg aggregation size increased. The lower per capita predation in larger larval aggregations than smaller groups conferred higher protection to A. monuste orseis larvae against natural enemies, through the dilution effects among individuals of the group. Parasitoidism was more intense in small-sized larvae while late instars were more susceptible to predators, regardless of aggregation size. Similar to species with solitary habit, behavioral events which involved head movements as searching and feeding were more dangerous to A. monuste orseis larvae compared to resting and walking. Presumed defensive behaviors were observed in all instars and treatments. Thus, the benefits of aggregation in A. monuste orseis can be seen especially in the egg stage and in first instars, as it reduces egg mortality and larval vulnerability to natural enemies. These benefits probably overcome some costs, such as interference competition in the late instars. Taken together, the results show that egg failure and top-down effects constitute selective pressures in maintaining egg and larval aggregation in A. monuste orseis, by providing better performance from a bi-trophic perspective and increased probability of individual survival from a tri-trophic perspective when compared to solitary individuals.

Cabagge (Brassica oleracea L. var. acephala), is attacked by several pests, being the caterpillar Ascia monuste orseis (Godart) (Lepidoptera: Pieridae), pointed as one of the most important, causing severe defoliation on plants. The main method of controlling this insect was done by the application of synthetic insecticides with recognized damage to the environment. Considering the importance of the insect for the cabagge culture and the undesirable effects arising of the insecticides application for their control, the present research had as objective to evaluate the resistance of cabagge genotypes against A. monuste orseis, and verify the types of resistance involved through the accomplishment of assays with adults (attractiveness and oviposition preference) and caterpillars (feeding preference and antibiosis), in laboratory and greenhouse conditions. A rearing of A. monuste orseis was maintained in the greenhouse in order to instal the bioassays. 29 genotypes of cabagge were evaluated: Manteiga de Ribeirão Pires I-2620 (MRP I-2620), Manteiga I-1811 (M I-1811), Roxa I-919 (R I-919), Manteiga de São Roque I-1812 (MSR I-1812), Gigante I-915 (G I-915), Manteiga I-916 (M I-916), Crespa I-918 (C I-918), Manteiga de Ribeirão Pires I-2446 (MRP I-2446), Crespa de Capão Bonito (CCB), Manteiga de Tupi (MT), Couve de Leguminosas (CL), Manteiga de Jundiaí (MJ), Manteiga de Mococa (MM), Manteiga São José (MSJ), Verde-escura (VE), Pires 1 de Campinas (P1C), Pires 2 de Campinas (P2C), Japonesa (J), Hortolândia (H), Orelha de Elefante (OE), Vale das Garças (VG), Comum (C), Introduções do município de Arthur Nogueira: variedades...

Abstract: Cabagge (Brassica oleracea L. var. acephala), is attacked by several pests, being the caterpillar Ascia monuste orseis (Godart) (Lepidoptera: Pieridae), pointed as one of the most important, causing severe defoliation on plants. The main method of controlling this insect was done by the application of synthetic insecticides with recognized damage to the environment. Considering the importance of the insect for the cabagge culture and the undesirable effects arising of the insecticides application for their control, the present research had as objective to evaluate the resistance of cabagge genotypes against A. monuste orseis, and verify the types of resistance involved through the accomplishment of assays with adults (attractiveness and oviposition preference) and caterpillars (feeding preference and antibiosis), in laboratory and greenhouse conditions. A rearing of A. monuste orseis was maintained in the greenhouse in order to instal the bioassays. 29 genotypes of cabagge were evaluated: Manteiga de Ribeirão Pires I-2620 (MRP I-2620), Manteiga I-1811 (M I-1811), Roxa I-919 (R I-919), Manteiga de São Roque I-1812 (MSR I-1812), Gigante I-915 (G I-915), Manteiga I-916 (M I-916), Crespa I-918 (C I-918), Manteiga de Ribeirão Pires I-2446 (MRP I-2446), Crespa de Capão Bonito (CCB), Manteiga de Tupi (MT), Couve de Leguminosas (CL), Manteiga de Jundiaí (MJ), Manteiga de Mococa (MM), Manteiga São José (MSJ), Verde-escura (VE), Pires 1 de Campinas (P1C), Pires 2 de Campinas (P2C), Japonesa (J), Hortolândia (H), Orelha de Elefante (OE), Vale das Garças (VG), Comum (C), Introduções do município de Arthur Nogueira: variedades...

Abstract:

Abstract Both the length of the season that is favourable for insect growth and reproduction and the number of generations emerging per season (voltinism) increase with decreasing latitude. Thus, time constraints on reproduction and juvenile development decrease with decreasing latitude, except where voltinism changes and time constraints suddenly increase as the season must be shared with one more generation. I studied the evolution of insect life histories in relation to time constraints from two perspectives: polymorphism and clinal variation. Life history polymorphism in seasonal environments was studied with the butterfly Pieris napi that has discrete life history strategies, and polymorphic natural populations. Experimental studies showed that asymmetric intraspecific larval competition and divergent timing of reproduction between the strategies may promote the maintenance of polymorphism. A simulation model showed that the divergent timing of reproduction between the strategies is sufficient to maintain polymorphism even in the absence of intraspecific competition. Clinal variation was studied empirically with four geometrid moths (Cabera exanthemata, Cabera pusaria, Chiasmia clathrata and Lomaspilis marginata) and generally in theory. Due to latitudinal saw-tooth variation in time constraints, traditional theory predicts a saw-tooth cline in body size and development time. A common garden experiment with the four geometrid moths did not support the traditional theory even when a saw-tooth cline in body size was found, suggesting that the theory is based on unrealistic assumptions. A theoretical analysis showed that reproductive effort should be high in populations under intense time constraints and low in populations experiencing no time constraints, resulting in a saw-tooth cline. In the four geometrid moths, support for these predictions was found, although the observed clinal variation deviated from the predicted pattern. The results imply that clinal variation is expected in almost any continuous life history trait, whereas polymorphism of different strategies may emerge when life histories fall into discrete categories. When inferring the evolution of a single trait, complex interdependencies among several traits should be considered, as well as the possibility that the time constraints are not similar for each generation in multivoltine populations
Tiivistelmä Hyönteisten kasvu ja kehitys ovat pääsääntöisesti mahdollisia vain kesän aikana. Etelään päin mentäessä kesä pitenee, ja saman kesän aikana kehittyvien hyönteissukupolvien määrä kasvaa. Kesän pituus aiheuttaa lisääntymiseen ja toukkien kasvuun kohdistuvan aikarajoitteen, joka heikkenee etelään päin siirryttäessä. Aikarajoite kuitenkin tiukkenee siellä, missä yksi uusi sukupolvi ehtii juuri kehittymään saman kesän aikana, sillä kesä on nyt jaettava useamman sukupolven kesken. Väitöstyössä tarkastelin hyönteisten elinkierto-ominaisuuksien evoluutiota suhteessa aikarajoitteisiin sekä diskreetin että jatkuvan muuntelun näkökulmista. Diskreettiä muuntelua tutkin lanttuperhosella (Pieris napi), jolla esiintyy diskreettejä elinkiertostrategioita. Kokeellisesti osoitin, että toukkien välinen kilpailu on epäsymmetristä, mikä yhdessä eri elinkiertostrategioiden erilaisen lisääntymisen ajoittumisen kanssa voi ylläpitää diskreettiä muuntelua. Simulaatiomalli osoitti, että erilaiset elinkiertostrategiat voivat säilyä populaatiossa pelkästään niiden erilaisen lisääntymisen ajoittumisen ansiosta. Elinkierto-ominaisuuksien jatkuvaa muuntelua tutkin neljän mittariperhosen (Cabera exanthemata, Cabera pusaria, Chiasmia clathrata ja Lomaspilis marginata) avulla ja teoreettisesti yleisellä tasolla. Aikaisempi teoria ennustaa ruumiinkoon ja kehitysajan muuntelevan sahalaitakuvion mukaisesti siirryttäessä pohjoisesta etelään, koska aikarajoitteet muuntelevat samalla tavalla. Tämä teoria perustunee epärealistisiin oletuksiin, koska kokeelliset tulokset eivät tukeneet teoriaa silloinkaan, kun mittariperhosten ruumiinkoko muunteli ennustetulla tavalla. Teoreettinen tutkimus osoitti, että myös lisääntymispanostuksen tulisi muunnella sahalaitakuvion mukaisesti suhteessa kesän pituuteen siten, että se on korkeimmillaan siellä, missä aikarajoitteet ovat tiukat. Mittariperhosten tutkiminen antoi jossain määrin tukea tälle ennusteelle. Tulosten perusteella jatkuvaa maantieteellistä muuntelua ennustetaan elinkierto-ominaisuuksille, jotka muuntelevat jatkuvalla asteikolla. Erilaiset elinkiertostrategiat voivat sen sijaan säilyä populaatiossa, jos elinkierto-ominaisuuksien muuntelu on diskreettiä. Eri ominaisuuksien monimutkaiset vuorovaikutukset sekä eri sukupolvien mahdollisesti kokemat erilaiset aikarajoitteet olisi syytä tuntea, kun tarkastelun kohteena on yksittäisen ominaisuuden evoluutio

Abstract:

Lagartas de Ascia monuste (Lepidoptera, Pieridae) são especialistas em Brassicaceae, sendo uma das maiores consumidoras desta família da região Neotropical. No campo, uma grande proporção de lagartas migra para outros hospedeiros e freqüentemente deparam-se com variações nutricionais e espaciais de alimento. O presente trabalho teve como objetivo principal estudar a performance dos imaturos de A. monuste em quatro combinações de alimentações, com hospedeiros alimentares diferentes numa mesma fase ontogenética, utilizando-se três hospedeiros naturais: couve (Brassica oleracea var. acephala) e rúcula (Eruca sativa), e couve e repolho (B. oleracea var. capitata). Estas plantas diferem quanto ao conteúdo de nitrogênio, com couve e rúcula tendo quantidades semelhantes e maiores que o repolho. Além disso, foi avaliado, tanto em campo quanto em laboratório, se a experiência alimentar prévia influencia na escolha de alimento no instar larval subseqüente, e quais seriam os efeitos de um período de privação de 24 horas de alimento, antes da mudança de hospedeiro, sobre a performance do inseto. Apesar de pequenas diferenças digestórias, possivelmente causadas pela adequação às diferenças de nutrientes, o tempo de desenvolvimento não diferiu significativamente entre os tratamentos; houve uma porcentagem de emergência e fecundidade potencial altas. De acordo com os resultados encontrados no presente estudo, rúcula e repolho seriam os hospedeiros de valores nutritivos semelhantes e couve, o hospedeiro de valor nutritivo diferente (e mais adequado para a performance de A. monuste). Pupas originadas de lagartas alimentadas com rúcula e repolho apresentaram, de uma forma geral, menor quantidade de massa e menos oócitos, inclusive quando houve privação alimentar entre os hospedeiros. A preferência alimentar por rúcula, ao invés de couve, e por couve, ao invés de repolho, independente do alimento prévio, mostra que a experiência prévia não determina a escolha por hospedeiros em imaturos em A. monuste. A preferência em campo diferiu daquela encontrada em laboratório. A privação de 24 horas de alimento entre a mudança de hospedeiros não provocou danos adicionais na performance das lagartas alimentadas com couve e rúcula, mas aumentou as taxas de mortalidade dos grupos alimentados com couve e repolho.
Ascia monuste (Lepidoptera, Pieridae) caterpillars are Brassicaceae specialists, being one of the most important comsumers of this plant family in the Neotropical region. In the field, a high proportion of immatures migrates to other hosts in order to develop properly, probably facing some variation in terms of nutritional value and location of their hosts. The main objective of this study was to investigate how the feeding of caterpillars of same ontogenetic phase on different hosts [kale (Brassica oleracea L. var. acephala) and rucola (Eruca sativa L.), and kale and cabbage (Brassica olerace L. var. capitata)], affects the corresponding performance of A. monuste. The hosts above mentioned differ in their nitrogen content: kale and rucola have similar nitrogen quantity, and kale has higher quantity than cabbage. In addition, it was evaluated whether the previous host would influence food choice in subsequent larval instar, in the field and in laboratory, as well as the effects of 24 hours of food deprivation on immature performance before switching the host. Beside few differences caused by host switching, possibly by the differences in nutrient levels, all the feeding tests originated similar performances and viable adults. When the preference was determined by the first caterpillar ingestion, previous experience did not influence host choice: caterpillars chose rucola instead of kale, and kale instead of cabbage, independently of previous host. But, when preference was determined by the total amount of ingested food, previous experience acted as a fagoestimulant in kale and rucola as hosts. It was not possible to detect what determine larval preference in the field. All plants tested were attractive for the caterpillars and the migration may occur for hosts that are close and easier to find. The 24 h food deprivation did not increase the effects of host change, but did present some differences. Rucola and cabbage could be less adequate hosts on final instars, because pupae whose larvae ingested these crucifers presented, in general, less pupal mass and also less oocytes, even when food deprivation does not occured.

Abstract:

Three formulations of Bacillus thuringiensis Berliner subsp. kurstaki (Dipel 4L, Dipel 2X, and ABG-6167) were compared with the synthetic pyrethroid perrnethrin ( common name Pounce 3. 2 EC) for insecticidal activity and impact upon parasitism of the imported cabbageworrn, Pieris rapae (L.) (Lepidoptera: Pieridae) in field broccoli (CV Packrnan) from fall 1986 to spring 1988. Perrnethrin, Dipel 4L, and ABG-6167 were not significantly different in their efficacy towards imported cabbageworm larvae. Parasitization of P. rapae by the larval parasite Cotesia glomerata (L.) (Hymenoptera: Braconidae) and the pupal parasite Pteromalus puparum (L.) (Hyrnenoptera: Pteromalidae) continued after spraying in the B. thuringiensis plots, but was not significantly different from perrnethrin. However, 100% of the P. rapae chrysalids recovered were parasitized by P. puparum. The impact of seasonal hyperparasitism was compared between .Q. glomerata, and a Yugoslavian strain of Cotesia rubecula (Marshall), an exotic larval parasite of the imported cabbageworm. Four hyperparasites, two of them attacking both~. glomerata and~. rubecula, were found in field plots from 1986-1988. The level of hyperparasitization for the two primary parasites was significantly different. Hyperparasitization averaged only 8.1% for C. glomerata from 1986-1988, but was 37. 9% for C. rubecula from 1987-1988. During the early- to mid-season of 1988, hyperparasite activity was not detectable and C. rubecula outcompeted C. glomerata for hosts; but by mid-season, hyperparasite activity against C. rubecula increased to 100%, causing its populations to crash. C. glomerata then became the dominant parasite of P. rapae. C. rubecula was not recovered in 1989. Hyperparasites may be a limiting factor in establishing C. rubecula in southwestern Virginia. Mortality and successful pupation of P rapae fourth instars parasitized by C. rubecula to B. thuringiensis endotoxin at dosages of 850, 85, and 8.5 I.U./ml was examined. After day two, the LC₅₀'s of parasitized fourth instars were approximately thirty times higher than that of unparasitized larvae and by day four, the LC₅₀ response of parasitized fourth instars was 180 times higher than unparasitized larvae. Twenty-five percent of parasitized fourth instars exposed to a concentration of 850 I.U./ml successfully pupated, compared to 76% at 85 I.U./ml and 69% at 8.5 I.U./ml. Parasitized fourth instar P. rapae consume less food and are therefore less susceptible to B. thuringiensis than unparasitized larvae at the same dosages.

Atualmente, a demanda por alimentos saudáveis e formas de produção menos agressivas ao ambiente e a saúde humana tem levado à busca por sistemas de produção mais sustentáveis. Neste contexto, a utilização de plantas bioativas e o resgate de técnicas utilizadas pelos agricultores familiares vêm sendo empregadas como alternativas para o manejo de insetos nos sistemas de produção de base ecológica. Desta forma, o objetivo do trabalho foi avaliar o potencial de Tagetes minuta (Asteraceae) no manejo da Ascia monuste orseis (Lepidoptera: Pieridae) em couve (Brassica oleracea var. acephala). Os trabalhos incluíram bioensaios de laboratório e experimentos de campo. Em laboratório, foram avaliados: consumo foliar (com e sem chance de escolha), biologia do inseto (ação de ingestão e contato) e ação sobre posturas. No bioensaio de consumo sem chance de escolha, os tratamentos testados foram extrato de flor e folha 10 e 30% (v/v) com e sem adjuvante (farinha de trigo 1% p/v) e óleo essencial de flor e folha 0,25, 0,5 e 1% (v/v) na alimentação de lagartas com três dias de vida. No consumo foliar com chance de escolha os tratamentos foram extrato de flor e folha 10 e 30% (v/v) e óleo essencial de flor e folha 0,5 e 1% (v/v), aplicados á alimentação das lagartas com seis dias de vida. Biologia de vida pela ação de ingestão e contato com os tratamentos extrato de flor e folha 10 e 30% (v/v) com e sem adjuvante (farinha de trigo 1% p/v) e óleo essencial de flor e folha 0,25, 0,5 e 1% (v/v) e ação ovicida dos extratos de flor 10 e 30% (v/v) com e sem adjuvante (farinha de trigo 1% p/v), e óleo essencial de flor 0,25, 0,5 e 1% (v/v) sobre ovos. Todos os bioensaios foram confrontados com as testemunhas água e óleo de nim 1% v/v. Na experimentação de campo foram aplicados semanalmente sobre couve os extratos de flor e folha de T. minuta 30% (v/v) com adjuvante, comparados à testemunha água destilada, no manejo de insetos fitófagos. Os resultados dos bioensaios em laboratório demostraram que no consumo foliar com e sem chance de escolha o extrato de flor 10% (v/v) reduziu o consumo foliar. Na biologia do inseto, extratos de flor e folha foram eficientes na ação de ingestão, assim como extratos e óleo essencial de folha foram eficientes na ação de contato, enquanto o óleo essencial de flor e folha a 1% (v/v) e óleo de flor (0,5%; 1% v/v) foram eficazes, respectivamente sobre a mortalidade e redução da eclosão de lagartas. No experimento de campo os extratos de flor e folha 30% (v/v) com adjuvante reduziram a população de insetos fitófagos em couve. De forma geral, os resultados evidenciam o potencial de T. minuta para manejo de A. monuste orseis, configurando-a como uma alternativa de fitoproteção que poderá ser utilizada na produção agroecológica de brássicas.
Currently, the demand for healthy foods and for the ways of production that are less harmful to the environment and human has led some researchers study about sustainable production systems. In this context, the use of bioactive plants and techniques used by farmers are being used as alternatives for the insect management in production systems with ecological basis. Thus, the aim of this study was to evaluate the potential of Tagetes minuta (Asteraceae) in the management of Ascia monuste orseis (Lepidoptera: Pieridae) in kale (Brassica oleracea var. acephala DC). The study included laboratory bioassays and field experiments. In the laboratory, it has been evaluated: leaf consumption (with and without choice), insect biology (intake action and contact) and action on postures. In the bioassay of no-choice consumption, the treatments were made in leaf and flower extract using 10 and 30% (v/v) with and without adjuvant (flour 1% v/v) and essential oil of flower and leaf 0.25, 0.5 and 1% (v/v) for feeding caterpillars after three days they had hatched. In leaf consumption of freechoice, the treatments were the flower and leaf extract, 10 and 30% (v/v) and essential oil of flower and leaf 0.5 and 1% (v/v) applied to the food of caterpillars after six days they had hatched. Life biology by ingestion and contact with the flower and leaf extract treatments 10 and 30% (v/v) with and without adjuvant (flour 1% v/v) and essential oil of flower and leaf 0.25, 0.5 and 1% (v/ v) and ovicidal action of flower extracts 10 to 30% (v/v) with and without adjuvant (flour 1% v/v), and flower essential oil, 25, 0.5 and 1% (v/v) on eggs. All the bioassays were compared to the witnesses: water and neem oil 1% (v/v). In the field experiment, it has been applied weekly on kale, the aqueous extracts of flo wer and leaf T. minuta 30% (v/v) with adjuvant, compared to distilled water witness for the management of phytophagous insects. The resu lts of the bioassays in the laboratory have shown that the leaf consumption with and without choi ce, the flower extract 10% (v/v) reduced the leaf consumption. In insect biology, flower and leaf extracts were effective in the intake action, the same way th at extracts and essential oils of leaf were effective in the contact action. While the essential oil of flower and leaf 1% (v/v) and flower oil (0.5%, 1% vvv) were effective, respectively, in the reduction of mortality and hatching of caterpillars. In the field experiment the flower and leaf extracts 30% (v/v) using adjuvant reduced the population of phytophagous insects in kale. In short, the results show the potential of T. minuta for the management of A. monuste orseis by setting as a phytoprotection alternative that can be used in agro-ecological production of brassica.

Abstract:

This work was performed to test the effect of aqueous extract of Cabralea canjerana subsp. polytricha (Meliaceae) in the control of Brevycorine brassicae (Hemiptera: Aphididae) and Ascia monuste orseis (Lepidoptera: Pieridae). Extract of leaves, fruits and seeds of 3, 5 and 10% were obtained through infusion of dry and triturated material in distilled water filtered after 24 hours. The effect of the extracts was tested in the survival of B. brassicae and the viability, larval and pupal weight and repellent/antifeedant activity of A. monuste orseis. Extract of 3 and 5% did not demonstrated insecticide action on B. brassicae. However, extract of 10% of concentration was able to control this insect in laboratory conditions. The larvae of A. monuste orseis demonstrated low viability when treated with leaves immersed in the extracts, dying before completing four days of age, on average. The evaluation of the repellent/antifeedant effect of the extract indicates that, in tests with choice, the individuals tend to avoid leaves treated with seeds extracts. Differences in consumed area were only demonstrated in the tests using extract of 10%. However, cabbage leaves immersed in fruits and seeds extracts presented a lower consumed area. Tests without choice indicate that when extract of 5 and 10% were used, cabbage leaves consumption was reduced.
Este trabalho teve como objetivo testar o efeito de extratos aquosos de Cabralea canjerana subsp. polytricha (Meliaceae) no controle de Brevicoryne brassicae (Hemiptera: Aphididae) e Ascia monuste orseis (Lepidoptera: Pieridae). Extratos de folhas, frutos e sementes a 3, 5 e 10% foram obtidos por infusão de material seco triturado em água destilada, filtrados após 24h. O efeito dos extratos foi testado na sobrevivência de B. brassicae e viabilidade, peso larval e pupal e atividade repelente/deterrente em A. monuste orseis. Extratos a 3 e 5% não demonstraram ação inseticida sobre B. brassicae. Todavia, extratos a 10% de concentração realizaram controle deste inseto em condições de laboratório. As larvas de A. monuste orseis demonstraram baixa viabilidade, quando alimentadas com porções foliares tratadas, não ultrapassando os quatro dias de idade, em média. A avaliação do efeito repelente/deterrente dos extratos indicou que, em testes com chance de escolha, os indivíduos tenderam a evitar folhas tratadas com extratos de sementes. Diferenças na área consumida só foram demonstradas em testes com extratos a 10%. Todavia, folhas de couve imersas em extratos de frutos e sementes apresentaram uma menor área consumida. Testes sem chance de escolha indicaram que quando extratos a 5 e 10% foram usados, o consumo das folhas foi reduzido.

Abstract:

The seasonal abundance of the imported cabbageworm, Artogeia rapae (L.)), cabbage looper Trichoplusia ni (Hubner)) and diamondback moth (Plutella xylostella (L.)) was determined in 1982 to 1984 on cabbage in southwest Virginia. The imported cabbageworm was the most important pest. It had one and a partial second generation in 1982 and 1983, and two and a partial third generation in 1984. Market Prize and Green Winter varieties had lower A. rapae infestations than Abbott & Cobb #5 or Rio Verde. Two generations of the diamondback moth, which preferentially fed on cabbage leaves versus heads, were seen in 1983 and 1984. Diadegma insularis (Meus.) (Hymenoptera: Ichneumonidae) parasitized 46% and 69% of the diamondback moth in 1983 and 1984, respectively. Higher parasitization of P. xylostella was found in pupae collected from Abbott & Cobb #5. Two generations of the cabbage looper were seen in 1983 and a single generation in 1984. Pteromalus puparum (L.) (Hymenoptera: Pteromalidae) parasitized 64.1% and 32.5% of imported cabbageworm pupae in 1983 and 1984; parasitism was most pronounced in the latter part of the season. High percentages of parasites successfully emerged as adults, indicating efficient host utilization. Most parasite mortality within the host occurred in the larval stage; mean adult parasite emergence per host for 1983 and 1984 was 52.3 with a 1:1 sex ratio. P. puparum parasitized either host sex, producing equal proportions of male and female parasites. Adult female P. puparum were not adversely affected by residues of methomyl (Lannate®), permethrin (Pounce®) and fenvalarate (Pydrin®), but males showed significantly higher mortality than controls following exposure to methomyl after 12 h, and methomyl and permethrin after six days. adults were successfully refrigerated for up to 15 days at 3°C in individual gelatin capsules. Survival beyond 15 days was better at l5°C and 23°C. A. rapae larvae could be reared at densities of 30 to 60 larvae per 70±10 g on a high wheat germ artificial diet. Pupae from the lowest density were larger in length and weight than those reared at the two higher densities, and all laboratory-reared pupae were smaller than either normal or parasitized field pupae.

Abstract:

Recent discoveries near the village of Nea Agathoupoli, in Pieria, Greece have revealed the remains of an ancient town, identifiable with the ancient town of Methone, a putative Eretrian colony founded, according to Plutarch, in ca. 733 BC. From the material excavated so far, the town’s zenith was in the Late Geometric and Archaic periods, well documented by the high amounts of imports from all regions of the ancient world, especially by imported transport vessels. The significant percentage of transport amphorae in comparison to that of fine pottery strongly indicates the settlement's commercial character and suggests that Methone was operating as a redistribution centre which supplied Macedonia's hinterland with goods. This study is based on unpublished pottery analyzed here, for the first time. Among the regions, whose products are most popular in Methone are Chios and Athens, although more Eastern Greek towns such as Samos and Miletus had trading relations with Methone, too. Settlers from the these regions may have established themselves in Methone, but the initiative for the foundation of the town was, most probably, taken by Euboeans, whose activity in the Northern Aegean, in the Geometric period, was strong. Alongside the abundant imported vessels, a large amount of locally made transport vessels was unearthed. These early archaic amphora types (early 6^th century BC), which have also been found in other sites in the Northern Aegean and possibly Northern Ionia, have been known in literature by my study. The discovery of these local transport vessels reveals participation by the local population in trading transactions and manufacture of a product which was packaged and circulated among the Northern Aegean towns. A mixed cultural environment starts to form in archaic Methone and includes Euboeans, Eastern Greeks, local Thracians and others, including Macedonian neighbours. Having emerged as the most powerful military force of the area, the Macedonians residing in nearby Bottiaia, constantly expanding, were, arguably, involved in the commercial activities at Methone. This study suggests that because of Methone's geographical location and proximity to the capital of the Macedonian kingdom, Aigai (modern Vergina), Methone functioned as the capital's face to the sea, as the royal harbour of Macedonia, until it was destroyed by Philip II, in 354 BC when all activities related to trade moved to neighbouring Pydna. Methone's finds together with other Northern Aegean settlements mentioned in this study reveal how important, even indispensable, this part of the ancient world was to the commercial networks of the archaic Mediterranean. The Northern Aegean is, therefore, not only well integrated into networks connecting southern and Eastern Greece, Egypt and the Levantine coast, but constitutes a vital part of them from the 8^th century BC, onwards.

Abstract:

El yacimiento de la mina Pierina que se explota hace más de 10 años, fue descubierto por la presencia de un megabloque ubicado en un paraje denominado Piruro. Es un yacimiento epitermal de alta sulfuración de oro-plata, alojado en rocas volcánicas del grupo Calipuy, depositadas en dos etapas, la primera entre 46 a 23 Ma y la segunda entre 16 a 13 Ma, con intervalo de inactividad volcánica para esta zona de aproximadamente 8 Ma. Para los fines del presente estudio, se tomaron en cuenta los eventos tectónicos de la Fase Quechua (Mioceno) y Fase del Cuaternario antiguo ocurridos en la región Perú. En esta etapa ocurrió el volcanismo y el tectonismo más importante relacionados con la mineralización y la posterior modificación de la anatomía original del yacimiento Pierina por efecto de la geodinámica externa. La deformación en la mina Pierina, se ha desarrollado mediante dos tipos de procesos, uno ocasionado por efectos de la geodinámica interna y el segundo por efectos de la geodinámica externa. La geodinámica interna, un proceso regional, ha permitido la formación del sistema de fallas regionales Roxana y Tinyash, las cuales originaron de forma alternada sistemas de fallas inversas, tensionales y de rumbo. A la geodinámica interna se le asocia los procesos de volcanismo e intrusiones de domos, y a las estructuras de cizalla asociadas a la alteración y mineralización. Asimismo, se ha reconocido que el último movimiento tectónico regional fue inverso y ocurrió en el Cuaternario antiguo reactivando las estructuras de cizalla alteradas y mineralizadas con fallamientos de movimiento inverso. La geodinámica externa trata los movimientos relacionados a esfuerzos de gravedad, naturales o provocados por el hombre a través de una serie de fallas del tipo Azucena y Milagros que ocasionaron y ocasionan deslizamientos rotacionales de grandes volúmenes de masas rocosas, modificando la anatomía original del yacimiento Pierina. La alteración y mineralización de la mina Pierina ocurrió entre 14.1 y 14.7 Ma., por efecto de fluidos hidrotermales transportados a través de las estructuras de cizalla Katty y Torta, este fenómeno fue de naturaleza pervasiva y se hizo más pervasivo aún cuando ingresó al dominio de las tobas de composición dacítica ubicadas en los niveles superiores de la secuencia volcánica. Las estructuras Katty están intensamente convertidas a “vuggy silica” que pasa lateralmente a cuarzo – alunita. Ellas presentan una variación en la mineralización, pues en los niveles más bajos de la alteración se presentan cristales de enargita en cavidades y pulvurulenta en las fracturas, interpretadas como producto del fracturamiento de las estructuras y consiguiente arrastre y trituración o milonitización. Los valores de oro son mayores a 1 g/t, pero, esta mineralización no es rentable por la presencia de sulfuros. Por su alteración, las estructuras de cizalla del cerro Torta son similares a las estructuras Katty; en este lugar el contenido de oro es más bajo, alrededor de 0.01 g/t. Producto de la geodinámica interna y geodinámica externa, las estructuras geológicas más saltantes formadas en el área de estudio son las fallas, que según la época que sucedieron guiaron la deposición de las rocas, mineralización, modelación y la reubicación espacial actual del depósito mineral. En las fotos aéreas de la zona del yacimiento Pierina, se observan dos grandes lineamientos estructurales denominados Tinyash y Mirador. Este último está expuesto en el tajo Pierina y es denominado como la Falla Roxana. Entre las fallas Tinyash y Roxana se ha producido la formación del sistema de estructuras de cizalla Katty, las cuales actuaron como los canales de alimentación para la mineralización del yacimiento Pierina. Posteriormente a la mineralización de Pierina, sucedieron hasta tres nuevos eventos tectónicos: Mioceno medio (10 Ma), Mioceno superior (7 Ma) y la fase del Cuaternario antiguo (2 Ma) que modificaron la posición inicial del yacimiento, deformándolo y exponiéndolo en superficie, provocando, además, su inestabilidad y deslizamiento en dirección de las pendientes propicias. Asimismo, tanto la falla Roxana, como las estructuras de cizalla, buzan hacia el lado sur, por lo tanto se asume que los fluidos mineralizantes provinieron de dicho sector. Restringidos por las rocas poco permeables de composición andesítica y flujos dómicos QFP, estos fluidos alcanzan su máxima mineralización y diseminación en las tobas de composición ácida. Por efecto del último movimiento inverso, ocurrido en las fallas Tinyash, Roxana y en las estructuras de cizalla, se produjo la exhumación de los bloques techo y su consiguiente deslizamiento a través de las fallas Milagros y Azucena. La falla Roxana se expone ampliamente en las paredes Oeste y Este del tajo, tiene un azimut aproximado de 125° y buzamiento variable entre 35° a 45°SW. La falla inversa, está evidenciada por la presencia de innumerables estructuras de arrastre y el “pitch” que indica su dirección de movimientos hacia N30° E. Las fallas inversas del cuaternario antiguo, expusieron los bloques techo, con la consiguiente desestabilización, alteración y formación de material supergénico (roca blanda) que posteriormente se deslizaron y se ubicaron formando los cerros Piruro, Torta, Quinquishinca y otros megabloques descritos en el texto. Actualmente, las fallas preexistentes se reactivan, son dinámicas e inestables, producen constantes deslizamientos durante las operaciones mineras, a estas fallas se les ha denominado Azucena y Milagros respectivamente. Con las consideraciones anteriores, en la mina Pierina se ha determinado tres zonas potencialmente vulnerables, en ellas se debe tener especial cuidado para realizar construcciones civiles posteriores: Zona A: Zona fallas Azucena Zona B: Zona fallas Milagros Zona C: Zona pozas de sedimentación
The gold deposit of the Pierina mine has been exploited for more than ten years now. It was discovered by the presence of a mega-block located in in the Piruro hill. Pierina is a high-sulphidation epithermal gold-silver deposit, hosted in volcanic rocks of the Calipuy group, which were deposited in two stages: the first one between 46 to 23 Ma and the second stage between 16 to 13 Ma, including a volcanic inactivity period for this area of approximately 8 Ma. For the purposes of this study, tectonic events of the Qechua phase (Mioceno) and ancient Quaternary phase have been taken into consideration.. The most important volcanic and tectonic activity related to mineralization events occurred in the Miocene. The modification of the original geometry of the Pierina deposit occurred later by the effect of external geodynamic events in the early Quaternary tectonic phase. The Miocene internal geodynamicwas a regional process, that allowed the formation of the Tinyash and Roxana regional fault systems, which at different times acted as inverse, tensional and strike-slip fault systems. Volcanism and dome intrusions, and shear structures associated with alteration and gold mineralization were linked to these internal geodynamic processes. Furthermore, it has been recognized that the last regional tectonic movement was inverse and occurred in the ancient Quaternary reactivating altered and mineralized shear structures showing reverse fault movements. External geodynamic was related to gravity movements, natural or man-made, through a series of faults like Azucena and Milagros which caused rotational landslides of large volumes of rock masses, modifying the original geometry of the Pierina deposit. The alteration and mineralization of the Pierina mine occurred between 14.1 and 14.7 Ma, as an effect of hydrothermal fluids transported along the Katty and Torta shear structures. This alteration-mineralization was pervasive and become even more pervasive in the dacitic tuffs located in higher levels of the volcanic sequence. The Katty structures were intensively silicified showing "vuggy silica" and laterally zoned quartz – alunite alteration. The lower levels of these structures contain enargite as crystals in cavities and pulvurulent in fractures, which has been interpreted as a result of intense fracturing of the structures followed by mylonitization and redistribution of the ore minerals. The gold values in the Katty structures are greater than 1 g/t, but are not economic due to the presence of sulfides. The alteration of the Torta shear structures is similar to the Katty structures, but the gold content is lower, about 0.01 g/t. The most striking geological structures formed in the study area are the faults, which led to the deposition of the volcanic rocks, mineralization, configuration of the geometry of the ore deposit and later the relocation of the mineralized bodies. In the aerial photos of the Pierina mine area, two major structural lineaments called Tinyash and Mirador have been mapped. The latter is exposed in the Pierina open pit and is registered as the Roxana fault. In the space between the faults Roxana and Tinyash, shear strctures were formed, which acted as feeders for the mineralization of the Pierina deposit. After the mineralization of the Pierina mine, up to three tectonic events occurred: Middle Miocene (10 Ma), Upper Miocene (7 Ma) and ancient Quaternary Phase (2 Ma), which deformed, exhumed the ore deposit and created the slope instability conditions that conducted to land slide movements of certain mineralized blocks. Furthermore, as the Roxana fault and the shear structures dip to the south side, it is assumed that the mineralizing fluids came from that sector. Constrained by low permeability rocks and andesitic flow domes QFP, these fluids reach their maximum expansion along the tuffs of acidic composition, which were mineralized. As a result of the last reverse movement, which affected the faults Tinyash and Roxana, as well as the shear structures, the hanging-wall blocks were exhumed and moved down slope along the Milagros and Azucena faults. The Roxana fault is widely exposed in the western and eastern walls of the open pit. It has an azimuth of approximately 125° anddip varying between 35° to 45° SW. The reverse fault is evidenced by numerous dragging structures, and the "pitch" indicate a movement direction towards N30° E. The reverse faults activated in the ancient Quaternary exposed blocks of the hanging-wall, leading to slope instability, alteration and formation of supergene material (soft rock), which subsequently slipped downwards and formed the hills named Piruro, Torta, Quinquishinca and other megablocks described in the text. Currently, the pre-existing Azucena and Milagros faults are still reactivated and remain unstable and dynamic.Repeated landslides occurred during the mining operation. Three potentially vulnerable areas have been identified, where special care must be taken to avoid damages to buildings and other civil constructions: Zone A: Zone of the Azucena faults Zone B: Area of the Milagros faults Zone C: Zone of the sedimentation pools

Abstract:

Geoarchaeology is the field of study that applies the concepts and methods of the geosciences to archaeological research. Geoarchaeological studies are important to archaeology because they can significantly enhance the archaeological interpretation. This thesis presents a geoarchaeological investigation of the processes involved in the formation of the Neolithic site at Paliambela in the Northern Pieria region of Central Macedonia, Northern Greece which unusually comprises both a tell and flat/extended componet. Chapter 1 presents an overview of geoarchaeology and its potentiality to unravel site formation processes. As geoarchaeology is an indispensable part of modem archaeological research can be used in concert with other archaeological subdisciplines such as archaeometry, to sharpen the interpretation of archaeological data and allow us to understand prehistory more fully. In this respect, Chapter 2 sets out the methods utilized ./ for the purposes of this study which were: particle-size analysis, microartifact analysis, magnetic susceptibility measurements, and organic carbon determination. Combinations of these methods can provide information critical to an understanding of the dynamics of the site's stratigraphy and ofthe formation of the deposits. ~hapter 3 presents and interprets the results of geoarchaeological analysis of core-data and of selected deposits (pits and ditches of the Neolithic period and pits of the Byzantine-Ottoman period) within the site while Chapter 4 explores the spatial organization of these deposits in more detail. The overall outcome of this analysis (Chapter 5) is the recognition that the formation of the archaeological deposits from both parts of the site, both temporally and spatially, was largely the result of differences in human activities and probably in the organization of human activities that seem to preserve to two components of the Neolithic site as spatially distinct over time while differences between the Neolithic and Byzantine-Ottoman contexts broadly indicate differences in the living environment between the prehistoric and historic settlement.

Les deux premiers chants de Lucain témoignent d'une utilisation novatrice des discours directs dans l'épopée. Présentés sous forme de triades de paroles juxtaposées -le dialogue n'est plus possible dans le monde du De bello ciuili- dont l'objectif et le genre sont similaires, ils incitent le lecteur-auditeur de l'Antiquité, rompu aux joutes oratoires des concours de déclamation, à les comparer. L'examen de deux de ces groupes de discours sert de préliminaire à une enquête plus large sur la parole rhétorique, puis sur la parole poétique.Dans la confrontation des discours de la première triade (Curion / César /Laelius, au chant I) se lit la condamnation de l'éloquence traditionnelle fondée sur des valeurs éthiques universellement partagées. Elle est supplantée par une rhétorique sophistique qui redéfinit, exclusivement en fonction des intérêts personnels de l'orateur, tout ce qui a trait au droit, au juste ou à la citoyenneté, notions problématiques dans le contexte de perversion morale du bellum ciuile. L'efficacité de cette nouvelle éloquence est signalée par le succès des trois suasoires qui sont à l'origine des grands tournants narratifs de l'œuvre : Curion décide César à entrer définitivement dans l'affrontement civil (Chant I), Cicéron pousse Pompée à donner le signal du début du combat à Pharsale (Chant VII) et Pothin persuade Ptolémée d'assassiner Magnus (Chant VIII).Dans la comparaison des trois paroles prophétiques de la fin du livre I auxquelles répondent les trois discours du début du chant suivant, effusions angoissées de Romains anonymes (les femmes, les hommes et le vieillard), se dessine un art poétique destiné à justifier les choix génériques du poète pour traiter son sujet. Conformant son œuvre à la médiocrité humaine des masses, il doit renoncer au genre tragique (discours des femmes) ainsi qu'à la célébration épique des héros (discours des hommes) et s'efforcer de proposer, à l'instar du vieillard qui se remémore le passé pour anticiper le futur (le plus long discours de l'épopée, rappelant, par sa place et son sujet, l'ilioupersis d'Enée), une épopée historique qui cherche à percer l'opacité du monde de la guerre civile, dans lequel les dieux ne sont plus anthropomorphes. Empruntant leur esthétique du déchiffrement du réel aux Piérides ovidiennes, ces poétesses humaines, rivales des divines Muses (Métamorphoses V), Lucain refonde alors la persona de son uates. Chantre d'un genre nouveau, pour une épopée renouvelée, le 'piéridique' uates du De bello ciuili qui ne peut plus être omniscient -puisque les pensées et les actions des superi lui sont inconnaissables- refuse le patronage des divinités traditionnelles de la poésie, promet à son 'héros' César, non la gloire mais l'exécration éternelle et proclame avec défi, qu'il ne devra lui-même l'éternité qu'à la seule puissance de son talent personnel, divines Muses et grands guerriers héroïques des œuvres du passé ayant été congédiés par la guerre civile.

Abstract:

Fondée sur les ordres de Jules César peu de temps avant les Ides de Mars, la colonie de Dion (Piérie, Macédoine) fait partie d’un vaste programme de colonisation qui a touché tout l’empire à l’époque césaro-augustéenne. Les données épigraphiques, rassemblées en un corpus des inscriptions latines et grecques de Dion et de son territoire, permettent d’analyser, dans le temps et dans l’espace, les évolutions d’une société mixte, constituée des colons romains, de leurs descendants et des anciens habitants grecs. Dans cette société qui s’hellénise peu à peu, se met en place un panthéon original qui mêle les divinités romaines aux divinités grecques et orientales. Les éléments de romanité, dominant au début de la période, s’atténuent progressivement, alors que les institutions perdurent jusqu’à une date avancée du Bas-Empire
Founded on Julius Cesar's orders, shortly before the Ides of March, the Dion colony (Pieria, Macedonia) was part of a large colonization program that involved the whole empire at the Caesar and Augustan time period. The epigraphic data, in the form of a corpus collecting the Latin and Greek inscriptions from Dion and its territory, make it possible to analyse, in time and space, the evolution of a mixed society constituted of Roman settlers and their descendants, as well as native Greeks. In this progressively hellenising society, a distinctive pantheon arises, mixing Roman gods to Greek and Oriental ones. The roman elements, while dominating in the early era, will progressively fade although, the institutions will remain much later during the Late Empire

Abstract:

Like many other animals, butterflies are able to visually perceive the ultraviolet (UV) light; many species even have patterns on their wings which are visible in this part of the electromagnetic spectrum. Over the last forty years, it has been shown that these UV patterns play an important role in behaviour of many butterflies, especially in relation to sexual selection - they are involved in the process of recognising a suitable mate, and likely can signal some of the mate's qualities, such as its age, ability to handle stressful environmental factors, or efficiency in foraging. The patterns may also be used for taxonomical purposes. This dissertation thesis contains a comprehensive research into ultraviolet patterns of the Gonepteryx brimstones, with a primary focus on the issue of environmental influences in relation to the expression of these traits, on the patterns' potential role in sexual selection, or on their evolution. It has been successfully demonstrated that UV patterns of at least some Gonepteryx species are affected by the environment to a strong degree, significantly more than the traits not involved in sexual selection. On the whole, the conclusions made by submitted publications suggest that UV patterns play a role in the sexual selection of the chosen brimstones, though it is not clear...

On Taiwan Island, Pieris canidia (Sparrman, 1768) and P. rapae crucivora Boisduval, 1836 are two species of devastating agricultural pests cruciferous plants (Brassicaceae). The former is always considered a native species in Taiwan, while the latter was suggested to be incidentally invaded from Japan during 1960s. If P. rapae is indeed an invasive species, it should be subject to the founder effects which may reduce genetic divergence among the new populations. The present study is aimed to compare the population structure of two species in Taiwan and their phylogenetic relationships with populations of the surrounding areas using a fragment of COI gene. The results show high degree of gene flow between populations (Nm＝1.17-292) and the degree of haplotype diversity （h=0.372） and nucleotide deivesity (π＝0.00057) within populations of the native species of P. canidia in Taiwan was low. Gene flow (Nm＝0.84-59.67) is fluent between populations ofthe invasive species of P. rapae in Taiwan, with higher degree of haplotype diversity （h=0.792） and nucleotide deivesity (π＝0.003) within populations than those of populations of Japan (h＝0.216, π＝0.00039). This result does not agree with what should be expected in a population under founder effect. By using neighbor-joining analysis to reconstruct phylogenetic relationship it revealed that showed intermixed haplotypes of the P. rapae populations are found in Taiwan, Japan and China. Haplotypes found in Taiwan include a few found only in Japan or mainland China The degree of haplotype diversity and nucleotide deivesity within populations of P. rapae in Japan is low. It is suggested that the population of P. rapae in Taiwan was constructed by multiple invasion events from China and Japan, rather than a single invasion event from Japan.

Abstract:

Visual features of the wing colour, with special reference to the intensity of UV reflectance of the Green-veined White (Pieris napi) were investigated. Several studies revealed that only females of Pieris napi possess UV reflectance on dorsal wing surface. Based on UV sensitive photography, we analysed correlation between environmental conditions (productivity and climate) and 3 patches on forewing of 347 specimens of P. napi from Palaearctic region. Males significantly differ in level of intensity of UV reflectance from females. UV intensity in females is 25% higher in comparison with males. This phenomenon is explained by different deposition of wing pterins. Further, environment significantly affects UV intensity on the forewings of females, but not males. Moreover, we accomplished the analysis of fluctuating asymmetry. First we subjected the environmental variables to PCA. In females, the first PCA axis (temperature seasonality, temperature annual range and longitude) significantly correlated with UV intensity. In males, the second PCA axis (latitude and altitude) was significantly correlated with FA. Additionally, we performed Two-Block Partial Least- Squares (PLS) analysis to assess co-variation between intraspecific shape...

Abstract:

Pieris oleracea, formerly Pieries napi, was once a widespread pierid butterfly in New England until the introduction of a biological control agent, Cotesia glomerata. It has been suggested that C. glomerata is responsible for the range reduction of P. oleracea. There are been several introductions of a second more specialized biological control agent, Cotesia rubecula, to the United States since the 1960’s. My first goal was to determine the current distribution and status of P. rapae parasitoids and the effectiveness of C. rubecula as a biological control agent since its release. The findings of a survey I conducted of the parasitoid community of P. rapae indicate that C. rubecula now occurs as far west as North Dakota and has become the dominant parasitoid of P. rapae in the northeastern and north central United States and adjacent parts of southeastern Canada, where it has displaced C. glomerata, the previously dominant parasitoid. Survival of artificially established cohorts of P. rapae larvae was assessed in a collard patch on an organic vegetable farm in western Massachusetts. There was a significant drop in larval survival between the 4th and 5th instar due to parasitism by C. rubecula. This was change from survival curves of P. rapae from a 1985-1986 study, in which there was a significant drop in survival between the 5th instar and pupal stage due to C. glomerata. The final goal of my thesis work is to try to understand why P. oleracea was able to survive at the focal study site in Lenox, MA despite parasitoid pressure and range reduction elsewhere in New England. In olfactometer tests, there was no difference in attractiveness of naïve C. glomerata females to volatiles of either Cardamine pratensis (cuckooflower) foliage, the host plant of P. oleracea or Brassica olercea (collard) foliage (P = 0.51). In order to determine if overtopping by other vegetation may provide an enemy free space for P. oleracea by affecting detection by C. glomerata, cage experiments were conducted. Overtopping vegetation had a significant effect on parasitism by C. glomerata (F = 12.8, df = 3, PP. oleracea has been able to thrive at the Lenox, MA site.

Abstract:

Many species are sensitive to a light in ultraviolet spectrum. Some species have surface patterns that reflect ultraviolet light. These markings have been observed in many animal taxa; butterflies (Lepidoptera) are no exception. UV-reflectance in butterflies has been primarily connected to sexual selection and in this respect it has been a subject of many studies. In my work I propose an alternative view to this phenomenon. The aim of my work is to reveal how a particular environmental factors influence the morphospace of UV- reflectant patterns and wing shape of the Gonepteryx rhamni (Pieridae). The effect of various environmental factors (latitude, longitude, altitude, mean annual temperature, mean annual precipitation, normalized difference vegetation index - NDVI or net primary productivity - NPP) on wing morphospace was tested using the methods of Geometric morphometrics. I have also studied shape variability among the males and females, specimens from different locations and differences in morphospace of several G. rhamni subspecies. The dataset used in this analysis includes 118 males and 67 females from the Palearctic ecozone. The effect of almost all environmental (except to NDVI and NPP) predictors on shape of the UV-pattern and wing margin was significant in the case of males. In the...

Abstract:

The Pierina high-sulphidation epithermal Au-Ag deposit is located in the Cordillera Negra of north-central Perú, ~ 5km north of the coeval intermediate-sulphidation Ag–base metal Santo Toribio deposit, and in rocks of the Calipuy Supergroup. The deposit contains ~ 8 M oz Au, hosted in non-refractory iron oxides and, with heap-leach extraction, is one of the lowest-cost Au producers in the world. Stage Ia (15 Ma) and Ib (14.4 Ma) advanced-argillic alteration formed from mixed magmatic and meteoric waters. The main, 14.4 Ma event produced vuggy quartz alteration, focussed in a 16.9 Ma dacitic pumice-lithic tuff, and surrounded by quartz-alunite, quartz-dickite, and illite-montmorillonite alteration zones, the product of increased meteoric water contributions towards the periphery of the deposit. Stage II sulphide-barite mineralization introduced gold and silver, hosted submicroscopically in the disseminated high-sulphidation pyrite-enargite assemblage. Precipitation occurred from a low-to-medium - salinity magmatic fluid that mixed with meteoric waters at the site of ore deposition. A 14.1 Ma 40Ar/39Ar age for supergene alunite records the rapid incursion of meteoric waters into the deposit. The resulting oxidation of sulphides to schwertmannite, goethite, and hematite was facilitated by microbes, recorded by the stable-isotopic compositions of supergene barite+acanthite. Schwertmannite is enriched in Au and Ag and is the main precious-metal host. Regional pedimentation is inferred to have initiated retrograde boiling of the source magma chamber at 15 Ma, with renewed magma incursion triggering major alteration at 14.4 Ma. Both events involved the exsolution of an SO2-rich vapour and a more saline aqueous fluid. The latter migrated to Santo Toribio generating phyllic alteration and intermediate-sulphidation mineralization, whereas the SO2-rich vapours caused pyrite-bearing feldspar-destructive alteration along fluid pathways during ascent to Pierina. The subsequent single-phase, H2S-rich mineralizing fluid exsolved from the retracting magma at higher pressures. Vapour contraction during ascent along altered, unreactive pathways minimized the loss of S- and H+, optimizing the transport of Au as AuHS0. Watertable displacement resulting from pediment incision promoted the flow of groundwater into the epithermal environment where mixing with magmatic fluids precipitated gold. Supergene oxidation optimized conditions for microbial activity, a critical factor in the generation of economic mineralization.

Abstract:

Science communication, over the last two decades, has shifted its onus from public understanding to public engagement. These efforts have been paralleled in science education, which strives to promote continued student engagement with science. Persistence with more traditional forms of pedagogy by teachers in middle school is a chief deterrent to this endeavour. Since many teachers' inadequate understanding about science is regarded as inhibiting their use of inquiry-based pedagogy, professional development based on constructivist principles has been identified to remedy this problem. This study investigates the constructivist basis for a model of short-term professional development, which has not been addressed in the literature. The one-day workshops offered to middle school science teachers in Australia and overseas by the Centre for the Public Awareness of Science (ANU, Canberra) are investigated here. While the workshops did facilitate conceptual change in the teachers, it was found that the constructivist principles which were incorporated into the workshops' design and delivery were underpinned by science communication practices. The conclusions presented include: the possibility of a constructivist framework for short-term professional development; the need for greater involvement of science communication in science education reform; and the unique challenges which confront science teachers from non-Western cultures.
