Previous issue date: 2016-03-31<br>Os cupins são insetos eussociais cujos ninhos são frequentemente invadidos por outros animais conhecidos como termitófilos. Alguns termitófilos são tão especializados que só são encontrados em cupinzeiros. No entanto, os motivos para tal especialização permanecem desconhecidos. Tanto a estrutura física do cupinzeiro quanto os cupins podem representar recursos valiosos para os organisrnos capazes de superar as barreiras físicas e biológicas impostas por este ambiente. Dentre as características de invertebrados altamente especializados a vida no cupinzeiro, a fisogastria é apontada como uma das principais, permitindo ao termitófilo confundir seu hospedeiro através de mimetismo morfológico. Tais características estão presentes em coleópteros da família Staphylinidae e dípteros da família Phoridae. Os termitófilos fisogástricos possuem modificações morfológicas que lhes permitem serem alimentados pelos cupins. Tal característica levou a idéia de que a obrigatoriedade desses termitófilos está atrelada a uma dependência nutricional para com seu hospedeiro. Entretanto, em algumas espécies de termitéfilos a fisogastria esta relacionada com a viviparidade, sugerindo o uso do cupinzeiro como local seguro para o período de gestação. Esta dissertação teve como objetivos: (i) discutir a cerca das características que permitem a coabitação de besouros Staphylinidae em ninhos de cupins e (ii) testar a hipótese de que termitófilos fisogástricos vivíparos dependem não apenas dos indivíduos das colonias de cupins hospedeiros, mas também da estrutura física do cupinzeiro. A coabitação destes termitófilos em ninhos de cupins é permitidapor adaptações defensivas tais como a forma limulóide, que os protege de ataques da colônia hospedeira, enquanto permite que explorem os recursos do cupinzeiro tais como os jardins de fungos ou detritos deixados pelos cupins, ou por adaptações que permitem a integração com a colônia hospedeira tais como a fisogastria,que são utiizadas por termitófilos que exploram diretamente os cupins. Para o teste da hipótese levantada acima, foram realizadas análises morfológicas o histológicas do sistema reprodutivo de um termitófilo fisogáistrico e vivíparo, em busca de singularidades que implicassem na necessidade de viver enclausurado. Nossos resultados apontam para a existência de gravidez prolongada nas fêmeas e a necessidade do contatos frequentes entre machos e fêmeas. Ambos fatores podem exigir a Vida em um ambiente enclausurado porque em tais ambientes há redução de riscos e aumento das taxas de encontro interindividual.<br>Termites are social insects whose nests are often invaded by other animals known as termitophiles. Some of which being so specialized that may be found only inside termitaria. The reasons for such a specialization remain largely unknown. Both the physical structure of the termitarium and the termites can be valuabe resources for organisms able to overcome the physical and biological barriers imposed by this environment. Among the features of invertebrates highly specialized to live in ter- mitaria, physogastry is pointed as one of the most typical, allowing the termitophile to confuse its host by morphological mimicry. Such features are presented by Cole- optera in Staphylinidae family and by Diptera in Phoridae family. The physogastric termitophiles have morphological modifications which allow them be fed by the ter- mites, which convey the idea that the obligatoriness of these termitophiles would be linked to nutritional dependency towards his host. In some termitOphiles the phy- sogastry is associated with viviparity, suggesting the use of termitarium as a shelter for pregancy times. This dissertation aims to: (i) discuss the features that allow the cohabitation of the Staphylinid beetles in termitaria and (ii) test the hypothesis that physogastric termitophiles could depend not only of the host termites, but also of the physical structure of the termitaria. The cohabitation of these beetles in ter- mite nests are allowed by defensive adaptations such as a limuloid form, that protect the termitOphiles from attacks by the host colony, while allowing the former to ex- ploit termitaria resources such as fungus gardens and debris, or adaptations such as physogastry that allow the integration with the host colony, allow termitophiles to directly exploit the individuals which, being fooled by mimicry, dispense normal nest- mate care (e.g., trophalaxis) to the invading beetle. To test the hypotheses above, morphological and histological analysis of the reproductive system of a physogastric and viviparous termitophile were performed, searching for singularities that imply in the need for living in sheltered environments. Our results point to the existence of prolonged pregnancy in females and the need for frequent contact between males and females. Both features may require life in a cloistered environment because in such environments there is reduced risk and the increase of the rates of interindividual meetings.<br>Dissertação sem arquivo PDF.

Full textAbstract:
The tobacco (Nicotiana tabacum L.) is a crop of major importance to Rio Grande do Sul and Brazil, but there are few studies on biodiversity associated with cultivation. Therefore, the aim of this study was to survey the families of Coleoptera associated with organic cultivation of tobacco, analyzing richness and abundance, as well as the temporal and spatial distribution of these insects. Furthermore, it also aims to perform a comparative analysis between organic and conventional cultivation of tobacco. The study was conducted on a crop with organic management in harvest 2009/2010 and 2010/2011, in Santa Cruz do Sul, RS. In the 2009/2010 harvest was also assessed a crop managed conventionally, for comparative analysis. In organic cultivation, three sampling lines were defined in order "inside-out" of crop, corresponding to: (1) line whose edge shows the adjacent vegetation abundant, mainly composed of trees and shrubs of medium and large; (2) line whose adjacent vegetation consisted of native shrub and tree species with size smaller; and (3) line with the adjacent vegetation composed of forage plants. On the other hand, in conventional cultivation, a line sample single was delimited, towards out within the crop, for comparison purposes with the line "2" of organic crop. In each line were determined three sampling points ("outside, border and inside"); and a single point within the sampling, called "middle" point. At sampling points were installed four pit-fall traps and one Malaise. In organic cultivation, the samplings were conducted, weekly, from November 20th, 2009 to March 19th, 2010 and from November 3th, 2010 to January 21th, 2011. In conventional cultivation, was from November 23th, to December 28th, 2009. In organic cultivation, were collected 49.269 coleopterans, distributed into two suborders, 13 superfamilies and 32 families. Six families accounted for about 90% of the total collected, namely: Staphylinidae (37.28%), Chrysomelidae (33.40%), Nitidulidae (7.50%), Curculionidae (5.25%), Carabidae (3.10%) and Elateridae (3.09%). The temporal distribution of Coleopterans is related, primarily, to the cycle of culture, and a reduction in the number of insects collected occurs due the subsequent harvests of tobacco leaves. On points "inside" and "middle" and on sampling lines "1" and "2", the community of coleopterans was numerically larger. The chrysomelids, being phytophagous insects, were distributed in places where there was greater food availability. However, the landscape composition of vegetation adjacent to cultivation was instrumental in the spatial distribution of predator insects belonging to Staphylinidae, considering that the highest abundance was observed in areas with greater plant diversity. The management adopted in conventional cultivation had an impact on the community of Coleoptera, especially when considering the decrease in abundance of the insects of the families Chrysomelidae and Staphylinidae.<br>O tabaco (Nicotiana tabacum L.) é uma cultura de reconhecida importância para o Rio Grande do Sul e para o Brasil, porém existem poucos estudos a respeito da biodiversidade associada ao cultivo. Portanto, o objetivo do presente estudo foi realizar um levantamento das famílias de Coleoptera associadas a cultivo orgânico de tabaco, analisando a riqueza e a abundância, assim como a distribuição temporal e espacial desses insetos. Ainda, realizar uma análise comparativa entre cultivos orgânico e convencional de tabaco. O estudo foi conduzido em uma lavoura com manejo orgânico, nas safras 2009/2010 e 2010/2011, no município de Santa Cruz do Sul, RS. Na safra 2009/2010 foi avaliada, também, uma lavoura manejada convencionalmente, para análise comparativa. No cultivo orgânico, foram definidas três linhas de amostragem, no sentido fora-dentro da lavoura, correspondendo a: (1) linha cuja borda apresenta a vegetação adjacente abundante, composta principalmente por árvores e arbustos de médio e grande porte; (2) linha cuja vegetação adjacente foi constituída por espécies arbustivas e arbóreas nativas de menor porte; e (3) linha com a vegetação adjacente composta por plantas forrageiras. Já em cultivo convencional, foi delimitada uma única linha amostral, no sentido fora-dentro da lavoura, para fins de comparação com a linha 2 do cultivo orgânico. Em cada linha foram determinados três pontos de coleta ( fora, borda e dentro ); e um ponto único no interior da lavoura, denominado ponto meio . Nos pontos de coleta, foram instaladas quatro armadilhas tipo pit-fall e uma Malaise. No cultivo orgânico, as coletas foram realizadas, semanalmente, de 20 de novembro de 2009 a 19 de março de 2010; e de 3 de novembro de 2010 a 21 de janeiro de 2011. Já no cultivo convencional foi de 23 de novembro a 28 de dezembro de 2009. No cultivo orgânico, foram coletados 49.269 coleópteros, distribuídos em duas subordens, 13 superfamílias e 32 famílias. Seis famílias corresponderam a cerca de 90% do total coletado, sendo elas: Staphylinidae (37,28%), Chrysomelidae (33,40%), Nitidulidae (7,50%), Curculionidae (5,25%), Carabidae (3,10%) e Elateridae (3,09%). A distribuição temporal dos coleópteros está relacionada, sobretudo, ao ciclo da cultura em campo, sendo que ocorre uma redução no número de insetos coletados devido às colheitas sucessivas das folhas do tabaco. Nos pontos dentro e meio e nas linhas 1 e 2 de amostragem a comunidade de coleópteros foi numericamente maior. Os crisomelídeos, por serem insetos fitófagos, distribuíram-se em locais onde havia maior disponibilidade de alimento. Entretanto, a composição paisagística da vegetação adjacente à lavoura foi determinante na distribuição espacial dos insetos predadores pertencentes à Staphylinidae, tendo em vista que a maior abundância foi verificada nas áreas com maior diversidade vegetal. O manejo adotado em cultivo convencional teve impacto sobre a comunidade de Coleoptera, principalmente, ao se considerar a diminuição da abundância dos insetos das famílias Chrysomelidae e Staphylinidae.

Full textAbstract:
Corotoca Schiødte, 1853 é um gênero estritamente Neotropical de besouros termitófilos associados à cupins do gênero Constrictotermes Holmgren, 1910, e sua descoberta marca o primeiro registro de outros insetos vivendo associados a ninhos de cupim. Foi realizada a análise cladística e revisão taxonômica do grupo que até o início do presente trabalho contemplava cinco espécies. A análise cladística contou com 13 terminais (oito do grupo interno e cinco do grupo externo) e 67 caracteres, sendo 65 morfológicos e dois comportamentais. A busca exaustiva com pesagem igualitária resultou em uma árvore mais parcimoniosa (C=95). A topologia resgatou o gênero Spirachtha Schiødte, 1853 como grupo irmão de Corotoca com base em sete sinapomorfias, sendo uma homoplástica. O gênero Corotoca é monofilético e foi sustentado por seis mudanças, sendo quatro sinapomorfias únicas e duas sinapomorfias homoplásticas. São seis espécies associadas a Constrictotermes cyphgergaster (Silvestri, 1901): Corotoca araujoi Seevers, 1957, Corotoca dawkinsi sp. nov., Corotoca fontesi Zilberman, 2018, Corotoca hitchensi sp. nov, Corotoca melantho Schiødte, 1853, Corotoca phylo Schiødte, 1853. Um novo gênero foi criado, Cavifronexus gen. nov., para incluir duas espécies que ocorrem associadas a Constrictotermes cavifrons (Holmgren, 1910): uma espécie de Corotoca descrita para Guiana, Cavifronexus guyanae (Mann, 1923) comb. nov.; e outra para o Brasil, Cavifronexus papaveroi sp. nov. Os dois gêneros e as oito espécies foram descritos ou redescritos e ilustrados e chaves de identificação foram confeccionadas. Também estão incluídas notas de comportamento e um estudo do ciclo de vida do gênero Corotoca.<br>Corotoca Schiødte, 1853 is a strictly Neotropical genus of termitophiles beetles associated with termites of genus Constrictotermes Holmgren, 1910 and its discovered marks the first record of other insects associated with termites. The cladisc analysis was based on 13 terminal taxa and 67 characters, which 65 were morphological and two behavioral. The outgroups were selected based on the diversity of taxa and the availability of material for dissection. The exhaustive search with equally weighted characters found one most parcimounious tree with 95 steps. The topology recovered the genus Spirachtha Schiødte, 1853 as sister group of Corotoca, with seven changes, which six are unique synapomorphies and one homoplastic synapomorphie. The genus Corotoca is monophyletic and it is sustained by six changes, which four are unique synapomorphies and two homoplastic synapomorphies. There are six species associated with Constrictotermes cyphergaster (Silvestri, 1901): Corotoca araujoi Seevers, 1957, Corotoca dawkinsi sp. nov., Corotoca fontesi Zilberman, 2018, Corotoca hitchensi sp. nov., Corotoca melantho Schiødte, 1853, Corotoca phylo Schiødte, 1853. A new genus was established, Cavifronexus, to include a species of Corotoca previous described for Guiana, and a new species, Cavifronexus guyanae (Mann, 1923) (new combination) and Cavifronexus papaveroi sp. nov. respectively. Three new species were described and the remaining species redescribed, with key and illustration for all the species of both genera presented. This work also provides behavioral notes and a study of the life cycle of the genus Corotoca.

Los bosques de Polylepis (Rosaceae) son ecosistemas andinos importantes por la gran biodiversidad que presentan y además albergan fauna endémica en peligro de extinción. Sin embargo, estos ecosistemas cada vez son más vulnerables debido a la presión antropogénica. El bosque en estudio está conformado mayormente por Polylepis tomentella Weddell, con distribución restringida y en peligro de extinción (Decreto Supremo N° 043-2006-AG). En el Perú, la subfamilia Oxytelinae Fleming, 1821 está representada por 18 especies en 8 géneros, y constituyen uno de los grupos más importantes en términos ecológicos, desempeñándose como transformadores de materia orgánica en descomposición y como controladores de huevos y larvas de muchos dípteros. El objetivo de este trabajo fue elaborar un inventario de las especies de Oxytelinae del bosque de Polylepis tomentella del distrito de Chaviña (Lucanas-Ayacucho) entre los 3993 y 4170 msnm de altitud. La recolecta de especímenes se realizó en época húmeda (abril 2010, marzo 2012 y abril 2013) y en época seca (septiembre 2010 y junio 2013). Para la recolecta se usaron trampas de caída sin cebo y con cebo de pescado podrido y heces, trampas de interceptación de vuelo y trampas amarillas. Se recolectaron 165 individuos correspondientes a cuatro especies de las cuales tres resultaron ser nuevas especies para la ciencia. 108 individuos pertenecen a Anotylus peruvianus (Bernhauer, 1941), 18 a Platystethus sp. nov., 30 a Thinobius sp. nov. y nueve a Thinodromus sp. nov. Se reportó por primera vez el género Thinobius para Perú y se proporcionó una clave de determinación de los géneros de Oxytelinae para Perú. La población de Oxytelinae presenta una marcada diferencia entre ambas épocas de muestreo, siendo Anotylus peruvianus la especie más abundante en el bosque de Polylepis de Chaviña tanto en época húmeda como en época seca. Con esta investigación se confirmó la presencia de Oxytelinae en el bosque de Polylepis tomentella del distrito de Chaviña.<br>Tesis

O controle biológico conservativo diversifica o agroecossistema e aumenta à presença de inimigos naturais, incrementando o controle de pragas. As plantas herbáceas além de aumentar a biodiversidade do hábitat, exercem influência na composição das comunidades de insetos no campo incrementando o controle biológico conservativo. O objetivo deste estudo foi avaliar a diversidade, distribuição e sazonalidade de besouros associados ao solo em plantio de soja (Glycine max (L.) Merrill) com faixas de plantas herbáceas nas bordas. O estudo ocorreu entre novembro de 2014 e setembro de 2016 em Jaboticabal-SP. As amostragens foram realizadas com armadilhas tipo alçapão, em dois hectares de área cultivada. Foram analisados os índices de diversidade, abundância, distribuição espacial e sazonalidade de besouros associados ao solo. Resultados evidenciaram maior ocorrência de besouros carabídeos nas faixas de plantas herbáceas. Scarabaeidae e Staphylinidae, por sua vez, não obtiveram crescimento populacional nas áreas de maior diversidade vegetal. A distribuição de espécies de Carabidae e Scarabaeidae foi apresentada de forma agregada sendo que a ocorrência dos insetos dessa família foi influenciada principalmente pela temperatura e umidade relativa.<br>The reduction of plant diversity in agroecosystems can affect predator insect populations due to the restriction of shelter and food resources. Studies about the role of herbaceous plants have shown the increase of biodiversity and the influence of composition and distribution on predator insects communities in the field. These dates may assist in the elaboration of the conservative biological control management programs. The aim of this study was to evaluate the diversity and abundance of ground beetles in the agroecosystem with soybean crop (Glycine max (L.) Merrill) and evaluate the dispersion of these insects in the habitat. The study was performed between 2014 November and 2016 September in Jaboticabal- SP. The essay was made in the field with 2 ha of soybean crop and herbaceous plant in two edges and the sample was performed with pitfall traps. The dates were analyzed and the diversity, abundance, seasonality indexes and spatial distribution of insects were calculated. The results pointed out that herbaceous plants affect positively the carabid beetle occurrence, but not affect Scarabaeidae and Staphylinidae. The distribution of insects was aggregate in the agroecosystem and the meteorological factors affect the occurrence of Carabidae and Staphylinidae beetles.

Resumo: Dermatite de contato é uma inflamação na pele provocada por contato direto com um alérgeno e pode ser desencadeada por insetos. Em Coleoptera a principal família com espécies causadoras de dermatite é Staphylinidae, cujo gênero Paederus Fabricius, 1775 é o foco do presente trabalho. No Brasil são conhecidas cinco espécies de Paederus causadoras de dermatite: P. amazonicus Sharp, 1876; P. brasiliensis Erichson, 1840; P. columbinus Laporte, 1835; P. ferus Erichson, 1840 e P. rutilicornis Erichson, 1840. Apesar dos acidentes com Paederus no Brasil serem conhecidos desde o começo do século XX, existe uma carência de literatura taxonômica sobre essas espécies. Assim, o presente trabalho teve como principal objetivo realizar uma revisão taxonômica das espécies de Paederus causadores de dermatite no Brasil. Foram analisados 371 exemplares provenientes de diversas instituições nacionais e internacionais. Ao todo sete espécies foram redescritas e reunidas numa chave dicotômica. Cinco destas espécies são relatadas na literatura como causadoras de acidentes e duas são consideradas como novos registros de espécies causadoras de dermatite para o Brasil, P. mutans Sharp, 1876 e P. protensus Sharp, 1876 sp. rev.. As fêmeas de P. brasiliensis, P. ferus e P. rutilicornis apresentam placa genital. P. ferus e P. rutilicornis apresentam assimetria das mandíbulas. P. amazonicus e P. mutans compartilham o ápice do 9º esternito emarginado. Em P. columbinus e P. protensus o labro não possui dente mediano evidente. As distribuições geográficas mostram concentrações dos registros de algumas espécies em determinadas regiões do Brasil, como P. amazonicus e P. mutans, cujos registros estão na região Norte; P. columbinus nas regiões Norte e Nordeste; P. protensus no Nordeste e Minas Gerais; e P. ferus no Sudeste e Sul, já P. brasiliensis ocorre em todo o Brasil. Para P. rutilicornis não há exemplares com registro para o Brasil. Os resultados apresentados são de extrema importância para auxiliar na correta identificação das espécies, além de permitir avaliar o "status" atual do conhecimento sobre as suas distribuições no Brasil.

Full textAbstract:
The present study aims to investigate the diversity and flight activity of Staphylinidae in a citrus orchard of the Catania Plain (Sicily) using different sampling methods (car-net, window traps and pit-fall traps). The study looks at the complex of flying rove beetles with the aim of defining preliminarily the faunistic and zoogeographical structure of this family in the study area. A second aim of the study is to investigate, using window-traps and pit-fall traps, the spatial distribution of flying staphylinids inside the orchard and in adjacent habitats. The use of window traps and car-net allowed to analyse the monthly and daily flight activity of staphylinids and to analyse the flight circadian rhythm and its seasonal variation. Monitoring of wind and temperature also allowed to evaluate the effects these environmental factors on the flight activity.
170 taxa (species, subspecies and 20 morphospecies) of Coleoptera Staphylinidae were collected. Most of the species are eurytopic species or related to substeppic or steppic environments, usually saprophyles with broad ecological valence. 5 species (Pella leonhardi, Pronomaea sicula, Quedius caelebs, Tasgius globulifer evitendus and Tasgius pedator siculus) are endemics to Sicily, 1 species (Oxypoda flavissima) is new for Italian fauna, 11 species (Acrotona muscorum, Amischa decipiens, Amischa forcipata, Atheta testaceipes, Carpelimus fuliginosus, Dacrila pruinosa, Lithocharis nigriceps, Micropeplus porcatus, Neobisnius lathrobioides, Outachyusa raptoria, Pycnota paradoxa e Trichiusa immigrata) are new for Sicilian fauna. The chorological spectrum is coherent with the environment where the research took place: a large orchard plain characterized by prolonged summer aridity.
The results of the window trap sampling show significant differences in the abundance of the flying species between open areas inside the orchard characterized by herbaceous vegetation (Track) and the inside of the parcels of citrus grove (Citrus). On the other hand the Spearman rank correlation analysis demonstrates that the faunistic structures of this stations are similar.
Comparison between sampling with pit-fall traps and with windows traps one shows that these two sampling methods basically differ by the taxa captures frequencies, in addition to the complete absence of Ocypus o. olens in the window traps.
The occurrence of the maximum frequency of catches in the window traps in the spring (often in contrast with car-net data) suggests that in this period blooming and fruits marcescence processes are an attractive stimulus which causes an increase of flight activity.
Hourly sampling with car-net highlighted, in the most abundant species, that flight has a circadian rhythm characterized by morning and afternoon peaks with a break or a decrease at midday.
The beginning of flight activity coincides with dawn in summer period in Gabronthus maritimus and in Alaeocharinae and Oxytelinae (not examined at species level). Flight activity s end takes usually place at sunset or twilight. Flight activity after dusk up to an hour after sunset has been detected in the Paederinae Scopaeus debilis, Hypomedon debilicornis, Astenus b. bimaculatus and Astenus pallidulus.
There are also seasonal variations of the distance of morning and afternoon peaks from dawn and sunset: in winter they are far away from dawn and from sunset, in spring the afternoon peak gets closer to sunset, in summer morning peak moves closer to dawn and the afternoon one overlaps sunset, in autumn this two peaks move away from dawn and from sunset again.
From autumn to spring the beginning of flight activity is conditioned by temperature. High temperature seems to cause the extension of the midday break which in summer extends until mid-afternoon. Wind is also an environmental factor which influences flight: in several species wind s high speeds reduce flight s activities. However, afternoon peaks also occur in highly windy day.

Full textAbstract:
Necrophilous insects, if correctly identified, can provide useful forensic information. Research in this area has focussed on flies and beetles remain comparatively under-studied, partly because some adult carrion beetles are difficult to identify morphologically, as are their juvenile stages, often requiring specialist expertise in both cases. Molecular taxonomy has been proposed as a solution to these problems. DNA “barcodes" are short fragments of mitochondrial cytochrome oxidase I (COI) DNA that are anticipated to delineate species. This approach is becoming increasingly popular, but has been met with varying enthusiasm from taxonomists. This thesis examines their use in identifying forensically significant beetles.The DNA barcodes of 234 specimens of 25 forensically significant southern African beetle species from seven families (Cleridae, Dermestidae, Silphidae, Staphylinidae, Scarabaeidae, Trogidae and Histeridae) were obtained. Thirty-three initial barcode amplification failures were overcome by using primers other than the standard Folmer pair, undermining the barcode concept’s hope of universal primers that would allow even non-specialists to produce barcodes. Another 150 specimens (64%) entirely failed to yield barcodes, including 18 fresh specimens of three species of Trogidae, implying another lack of universality of the barcoding protocol. The majority of the beetles clustered with confamilials on neighbour-joining and maximum likelihood trees, but 1.3% of the barcodes failed to cluster with their respective families, raising questions concerning the associating power of barcodes. The identification tools of the GenBank and BOLD on-line DNA sequence databases identified 21% of the specimens to the species level, 6% of them correctly. There was evidence of a paralogous sequence in the Cleridae that, while supporting identification now that it has been associated with a morphological identification, would hamper attempts at identification by clustering or phylogenetic analysis.Distance and haplotype network analyses of the barcodes of six widespread species showed that they are not geographically structured. Barcodes are thus unlikely to be indicators of the region of origin of a species and will not determine whether a corpse has been relocated after death. To assess whether a different mitochondrial DNA fragment might address (some of) these problems, a 2.2 kb fragment extending from the 5’ end of the COI gene to the 3’ end of the Cytochrome Oxidase II (COII) gene was analysed for nine species. It was found that, for Dermestidae, Scarabaeidae and Histeridae, higher degrees of diversity occurred downstreamof the barcode region, but the region of highest diversity in the Cleridae was in the barcode region. Thus, finding a more reliable fragment along the COI-COII region for each family may make robust and guaranteed DNA-based identification of these beetles more likely. The possibility of a forensic specimen being incorrectly or not identified based on its barcode alone exists in about 40% of cases, even with the new barcodes reported here. Forensic science sets a very high bar in assessing the performance of its techniques, and it is concluded that barcodes currently have unsettling failure rates as court-worthy evidence.

L'apport de l'ecologie comportementale est essentiel dans la comprehension des comportements mis en jeu par les parasitoides lors des phases de recherche et d'evaluation des hotes. Cette approche considere que ces comportements sont optimises par la selection naturelle, du fait de leur forte implication dans le determinisme de la valeur adaptative des parasitoides. Dans le systeme tritrophique, cruciferes - delia radicum - aleochara sp, les strategies de selection des sites de ponte par la femelle de a. Bilineata et des hotes par les larves parasitoides de 1 e r stade de a. Bilineata et a. Bipustulata ont ete etudiees. La demarche analytique choisie a consiste a comparer les comportements observes chez les deux parasitoides etudies, aux predictions des modeles d'optimisation developpes chez les hymenopteres parasitoides. Les resultats montrent que les femelles de a. Bilineata maximisent leur valeur adaptative en selectionnant les sites de ponte fournissant les meilleures chances de succes parasitaire aux larves. Cette etude met egalement en evidence une forte adaptation des comportements de selection de l'hote par les larves de 1 e r stade des deux especes, a la qualite de l'hote, a la densite d'hotes disponibles et a la presence ou non de larves competitrices. L'ensemble de ces resultats montrent qu'il existe une convergence des comportements de selection entre les coleopteres et les hymenopteres parasitoides. L'acquisition, des memes strategies comportementales, independamment, dans deux taxons phylogenetiquement distants, suggere que ces strategies sont les plus efficaces pour repondre aux contraintes du mode de vie parasitoide. Ces resultats sont aussi discutes en vue de l'utilisation des deux staphylins pour lutter contre d. Radicum en culture de cruciferes. Aleochara bilineata s'avere etre l'espece possedant le plus grand nombre de criteres favorables a son utilisation en lutte biologique. Differentes perspectives sont proposees.

Previous issue date: 2012-02-24<br>Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>Por vários anos, ecólogos de comunidades concentram-se em desenvolver métodos adequados para a detecção de padrões em conjuntos de espécies e identificar processos capazes de gerar tais padrões. Entre estes processos, a presença do predador parece afetar a diversidade em várias comunidades. Além da predação, outras interações e as características intrínsecas das espécies envolvidas também são processos importantes na estruturaçã de comunidades, principalmente naquelas comunidades associadas a ninhos de insetos sociais. Sendo assim, o objetivo desta tese foi testar o efeito do predador sobre a diversidade de invasores, bem como algumas características intríınsecas que permitem a coexistência de espécies em ninhos de cupins. Para tanto, testamos as seguintes hipóteses: (i) a presença do predador afeta a diversidade de invasores em ninhos de cupins; (ii) existe um tamanho crítico de ninhos de cupins, acima do qual os coabitantes são mais prováveis de ocorrer; (iii) algumas espécies que co-habitam ninhos de cupins possuem e mimetismo químico. Dentre os co-habitantes de ninhos de cupins parece ter uma certa especificidade e os Staphylinidae são os mais comumente encotrados. Nossos resultados sugerem que o predador é importante fator regulador e da riqueza de espécies invasoras em ninhos de cupins, mas para a abundância de invasores o predador não é importante e sim o volume dos ninhos que regula esta abundância. Entre os invasores, os Staphylinidae obrigatórios parecem conseguir invadir ninhos menores que 3 l, por outro lado os inquilinos obrigatórios parecem conseguir se estabelecer após os ninhos atingirem um volume maior que 13 l. Dentre os invasores Staphylinidae, algumas espécies possuem hidrocarbonetos cuticulares similares aos de seus e hospedeiros, o que pode facilitar a sua permanência dentro dos ninhos sem e serem perturbados. Assim, o presente trabalho auxilia na compreensão dos fatores que podem afetar a coabitação em ninhos de cupins, mostrando a importância do predador e de mecanismos intrínsecas das espécies, como volume do ninho e capacidade de mimetizar os hidrocarbonetos dos seus hospedeiros, sobre a co-existência de espécies nesses ninhos.<br>For several years, community ecologists have focused on developing adequate methods of detecting patterns in species sets and to identify processes that might generate certain patterns. Among these processes, the presence of predator seems to affect the diversity in many communities. But, in addition to predation and other interactions the intrinsic characteristics of the species involved are also important, especially in communities associated with nests of social insects. Thus, this thesis aims to test the effect of the predator, as well as some inherent characteristics that allow the species coexistence inside termite nests. Therefore, we tested the following hypotheses: (i) the presence of predators affects the diversity of invaders in termite nests; (ii) there is a critical nest size above which cohabitants are more likely to occur, (iii) some species that cohabit inside termite nests have chemical mimicry. Among cohabitants species of termite nests seem to exist a termitophiles specificity. Staphylinidae family are the most common. Our results showed that in termite nests where predators are found inside have higher termi- tophile richness, but the abundance is not affected by predator but the nest’s volume is determinant. We have seen that obligatory Staphylinidae seems to be able to invade small nests, on the other hand, termite inquiline seems to be able to invade nest bigger than 16 l. In this family some species have cuticular hydrocarbons similar to those of their hosts, which can help those individual stay undisturbed inside the nests. Thus, this work contributes to understanding the role of predators on prey behavior and the effect on the diversity and also help to understand the mechanisms involved in the invasion and coexistence in termite nests.

Des avancées scientifiques sont nécessaires pour limiter l’impact qu’exerce l’urbanisation croissante sur l’environnement et comprendre le fonctionnement de la biodiversité urbaine. Dans cette thèse, nous avons analysé les effets à différentes échelles spatiales sur les patrons d’organisation de plusieurs taxons appartenant à la faune épigée, suivant trois axes : (1) étudier les communautés à l’échelle d’une grande agglomération, (2) étudier l’effet des corridors sur la dispersion et (3) modéliser la dispersion. Nous avons mis en évidence un effet majeur de l’urbanisation des paysages sur les communautés, plus important pour les espèces forestières qui sont remplacées par des espèces plus généralistes. Les corridors, en favorisant la dispersion permettent, pour partie, d’y remédier. Ces résultats ont été confirmés par le modèle de dispersion. Ces résultats ouvrent des perspectives dans la spatialisation du fonctionnement des communautés<br>Scientific insights are needed to limit the negative effects of urbanization and improve urban biodiversity. Thus, we analysed the effects of landscape on several ground –dwelling communities (multi taxa approach). We organized our research following three main axis: (1) response along an urbanization gradient, (2) the effect of corridors on the dispersal among urban landscapes and (3) simulation of the corridor effect using an individual based model (IBM). We observed strong and negative effects of the urbanized landscapes, stronger for forest specialist species which are replaced by more generalist species along the gradient. We highlighted a positive effect of corridors with some differences between taxa that could be explained by variation in their dispersal capabilities, confirmed by the model. The IBM has confirmed these results. This study opens new doors on the spatial configuration of local communities within the landscapes

Two study sites near Pretoria in the Transvaal were located in a summer rainfall climatic area, type 113d (Walter & Lieth 1964), on deep and in both open woodland and grassland. 2. Eleven study sites in the south-western Cape were distributed between two winter rainfall climatic areas, type IV in the Cape of Good Hope Peninsula and type III(IV)a (Walter & Lieth 1964) on the west coast. The west coast could be divided into two subregions, the coastal belt of deep calcareous sand and the Darling Hills comprising predominantly sandy soils with a higher clay fraction. Vegetation at the sites formed a gradient from low, dense pasture to taller sparser shrubland; The five pasture sites were distributed between all three subregions whereas the six shrubland sites were located only in the Cape of Good Hope Peninsula and on the west coastal belt. 3. Pitfall traps baited with cattle dung were used to sample dung beetle fauna over 24h periods once a week in the Transvaal, irrespective .of weather (three traps/site), and on three sunny occasions per month in the south-western Cape (ten traps/site) for one year. 4. A further 13 study sites used for back-up studies in the south-western Cape were concentrated into three localities, three in the Cape of Good Hope Peninsula, six on the west coastal plain and four-in the Darling Hills. These sites comprised different combinations of pasture (five sites) and shrubland (eight sites) habitats. Five traps at each site were baited on one 24h occasion each month over six months.

Full textAbstract:
The potential of different field boundary types in lowland farmland to contribute to arthropod biodiversity and sustainable agriculture was investigated. Field boundaries, categorised according to nationally applicable definitions, were found to represent ecologically differing habitats based on their woody abundance and the frequency of young and mature emergent trees. These habitat characteristics were determining factors in the community structure and composition of overwintering epigeal arthropods. Hedgerows supported the most species rich carabid and staphylinid assemblage. Degraded hedgerow boundaries supported the most equitable carabid community, and provided a refuge for carabid species with poor dispersal power to a greater extent that hedgerows or post and wire fences. The grassy and natural regeneration vegetation associated with post and wire boundaries supported high densities of all taxa particularly overwintering carabid and staphylinid polyphagous predators. A subset of all field boundary types was required for complete species representation, indicating that maximising the heterogeneity of field boundary habitats represented at the farm-scale will enhance arthropod biodiversity in farmland. Carabidae and Staphylinidae actively selected overwintering sites and the physiological condition of polyphagous predators was generally high. It was concluded that heterogeneous distributions in field boundaries were more likely to be the result of differential microhabitat selection rather than differential survival overwinter. This indicated that favourable overwintering microhabitats occurred in all field boundary types. Generally, overwintering survival did not appear to be a regulating factor in the population dynamics of polyphagous predators. Margins adjacent to pre-existing boundaries may contribute to enhanced densities and physiological condition of some polyphagous predators, both over winter and in early spring. The results were discussed in relation to field boundary management and agri-environment policy.

Doctor of Philosophy<br>Department of Entomology<br>Raymond A. Cloyd<br>The life history of the rove beetle, Atheta coriaria (Kraatz) (Coleoptera:Staphylinidae), predation against the fungus gnat Bradysia sp. nr. coprophila (Lintner) and compatibility with pesticides and plant growth regulators was investigated under laboratory conditions using Sunshine LC1 Professional Growing Mix as a substrate. Duration of life stages was 2.2, 7.1, and 7.8 days for egg, larva and pupa respectively, at 26°C, whereas total development time from egg to adult was 17.0 days. In addition, A. coriaria male and female adult longevity was 60.3 and 47.8 days. Average fecundity was 90.2 eggs per female and the number of adults produced per female was 69.1.
There were no significant differences in prey consumption when using second and third instar fungus gnat larvae as prey and starved and non-starved rove beetles. Overall, predation efficacy in Petri dishes was high (70 to 80%) as fungus gnat larval density increased with 3.9, 7.0, 11.1, and 15.3 larvae consumed in 24 hours after exposure of 5, 10, 15 and 20 fungus gnat larvae to one rove beetle adult. However, lower predation rates were found at different predator:prey ratios when using 1 to 5 rove beetles and growing medium as a substrate.
The direct and indirect effects of pesticides and plant growth regulators on A. coriaria were investigated under laboratory conditions. Rove beetle survival was consistently higher when adults were released 24 hours after rather than before applying pesticides. Acetamiprid, lambda-cyhalothrin, and cyfluthrin were directly harmful to rove beetle adults, whereas Beauveria bassiana, azadirachtin and organic oils were compatible with A. coriaria. Similarly, the plant growth regulators acymidol, paclobutrazol and uniconazole were not harmful to rove beetle adults. In addition, Beauveria bassiana, azadirachtin, kinoprene, organic oils, and the plant growth regulators did not negatively affect A. coriaria development. However, Beauveria bassiana did negatively affect rove beetle prey consumption. This study demonstrated that A. coriaria is not compatible with the pesticides acetamiprid, lambda-cyhalothrin and cyfluthrin, whereas there is compatibility with organic oils, Beauveria bassiana, azadirachtin, and the plant growth regulators. As such, these compounds may be used in combination with A. coriaria in greenhouse production systems.

Les techniques isoenzymatique et genetique permettent de regrouper des souches d'individus d'origines differentes (france, canada) dans les deux especes considerees. De plus, elles permettent de separer et de caracteriser chaque espece par rapport a l'autre. Outre des perspectives d'etudes de dynamique et de genetique des populations, ainsi que la comprehension des interactions a. Bilineata - a. Bipustulata, ces outils nous ont permis de confirmer et de caracteriser la souche de coleopteres utilisee dans ce travail. A. Bilineata presente l'originalite d'etre parasitoide de diverses especes de dipteres lorsqu'il est au stade larvaire et d'en etre predateur au stade adulte. L'evaluation du potentiel de cet insecte a reguler la presence du ravageur d. Radicum impose la comprehension des mecanismes qui lui permettent de gerer le renouvellement de ses generations. Ceci necessite une synthese explicative des differentes sequences predatrices et parasitaires existant, et demande un approfondissement des connaissances actuelles de la biologie de la reproduction et du developpement, ainsi que de la predation sur ce staphylin. Le developpement de a. Bilineata presente une grande plasticite vis-a-vis des hotes (especes, taille, phenotype), et des conditions exterieures (temperature, humidite). Cette plasticite permet a l'insecte de posseder une gamme d'hotes etendue et d'avoir une repartition geographique large. Enfin, elle pourrait lui permettre de suivre ses hotes potentiels sur une grande partie, et peut-etre meme sur la totalite de leurs aires de repartition. Une interdependance entre la reproduction et la predation est montree chez a. Bilineata. La presence du male a un impact negatif a court terme sur la femelle en reduisant sa longevite et son niveau de ponte. Cependant, elle est necessaire a moyen et long terme pour renouveler le stock de sperme present chez la femelle et entretenir un niveau de ponte stable. Le niveau de population du predateur influence donc son niveau de reproduction. Cette contrainte devrait imposer un equilibre instable entre la predation et le parasitisme. Cette hypothese implique l'existence de flux regulateurs et compensateurs de staphylins a diverses echelles (individuelle, plant et parcelle attaques par la mouche). La predation de a. Bilineata a ete abordee par l'etude de sa reponse fonctionnelle qui constitue l'approche traditionnelle pour apprecier l'impact d'un insecte predateur sur sa proie. Lorsque les predateurs sont peu nombreux et que les proies sont presentes en faible quantite, le staphylin reduit son activite de recherche en attendant des conditions plus favorables, c'est-a-dire des proies plus nombreuses. La presence de competiteurs impose un changement comportemental de a. Bilineata. Celui-ci augmente son activite de recherche et donc la probabilite de rencontrer des proies. Sa reponse fonctionnelle de type-iii tend alors vers une reponse fonctionnelle de type-ii. Dans cette situation, le predateur a tendance a ne plus controler sa proie. Le fait que le ravageur d. Radicum echappe au controle du predateur a. Bilineata peut permettre a ce dernier d'assurer son parasitisme, et par consequent le renouvellement de ses generations. L'existence de flux regulateurs et compensateurs precedemment decrits permettrait a l'insecte d'ajuster son impact en tant que predateur et en tant que parasitoide aux niveaux des populations de proies et par consequent d'hotes potentiels rencontres.

Although the research on myrmecophilous insects is dated back to the 19th century, certain aspects of fascinating relationship between hosts and their social parasites are not satisfactorily understood. The latest studies focus mostly on the systematics of myrmecophilous taxa, and bionomy remains neglected. Most of the myrmecophilous insect can be found among beetles (Coleoptera). These myrmecophiles reveal a broad spectrum of adaptations that allow them to live in close association with their host ants. These adaptations significantly differ among the well-integrated species on one hand and poorly integrated or non-integrated species of myrmecophilous beetles on the other. This study focuses at the comparison of behaviour in two species of myrmecophilous beetles, Claviger testaceus (Staphylinidae: Pselaphinae) as the member of integrated myrmecophiles, and Pella spp. (Staphylinidae: Aleocharinae) as poorly integrated or non-integrated beetle. My work shows significant differences in behaviour taking place after encounter of a beetle and an ant. Ants are more aggressive towards the non-integrated species, and at the same time, these beetles are well-adapted for aggressive behaviour from the ants. On the other hand, the integrated beetles do not possess many behavioural adaptations for the...

SUMMARY The assemblages of epigeic beetles were studied in various types of agroecosystems in the submontaneous area of Novohradske hory (South Bohemia, Czech republic). The research took place in years 2009 and 2011. There were sown various types of crops, in the target places, on which were established either biobelts (research 2009) or permanent green belts with trees and shrubs (research 2011) in past. The aim of the study was to assess, whether or how these landscape structures influence epigeic beetles. The datas were gathered by sampling ground beetles with ground traps. The collected material was put then through identification and this was the base for assessing the parameters of landscape structures influence on epigeic beetles. These parameters were: the species diversity, the abundance and the ammount of relict species. It was collected 3099 beetles and it was managed to identify 54 species at all. The interest groups of invertebrates were ground beetles/carabids (Carabidae) and rove beetles (Staphylinidae). The results differed for both groups. The rove beetles were generally more abundant, than ground beetles and most of them were found in crops in the year 2009. The lowest numbers were caught in crops 2011. There was a quite remarkable contrast between these two results. The species diversity of rove beetles was too lower, than the ground beetles? one. The results of biodiversity seemed to be strange so as the abundance was. The diversity was the highest in the crops 2009 and the slowest in the crops 2011. Nearly the same diversity was found in biobelts, which are really different type of habitat. The carabids? abundance was not so oscillating like by the rove beetles. They were the most abundant in biobelts and the less in permanent belts. The abundance in crops in both years was nearly the same. The species diversity was highest in permanent belts and the lowest in crops in the year of 2009. The results about antropic influence on epigeic beetles assemblages, based on ecological characteristics of beetles, were eventually raised. It was established, that all the populations are strongly affected by human. The results say, that habitats like biobelt and permanent belt seem to have a positive impact on epigeic beetles assemblages, namely on relict or rare beetles survival. The results have very disparate and sometimes contradictory nature, thus cannot be sumarized.

The aim of the study was to examine communities of epigeic beetles in the plantations of fast-growing trees (poplar clone Japanese J - 105 (Jap = - 105, Max - 4, Maxvier) and surrounding habitats (Zea mays L.). A cover of Zea mays L. was used as an area for comparison. Sampling was carried out in 2012 by using the method of epigeic beetles in pitfall traps (period from May to September). During the sampling, altogether 1054 specimens and 57 species of epigeic beetles were collected. In the area of fast-growing trees ?Na Vrbovecku? 528 specimens were collected which is many times more than in other researched areas. In the cover of Zea mays L. in the area "Na Vrbovecku" 293 specimens were collected and in the zone of fast-growing trees "U rybníka" 233 specimens were catched; notice the high similarity in the number of collected specimens. At all sites surveyed the expansive species (E) outnumbered the II relics. There were about 70% of expansive species in the cover of Japanese poplar found and in the cover of Zea mays L. there were about 90% of expansive species found. The number of more adaptable species- RII category- found in the cover of Japanese poplar was approximately 30% unlike the number of the same species found inside the Zea mays L. cover was only 12%. The rare species Xantholinus gallicus of the RI category was found in the plantations of fast-growing trees "U rybníka". The index of anthropogenic impact on communities (ISD) was very low in studied plots. In the Zea mays L.cover the index was only 6 points, unlike in the cover of Japanese poplar where the index reached 24 points. Yet all researched areas show high anthropogenic impact. Based on the obtained results (epigeic beetles), it seems that plantations of fast-growing trees have a positive impact on communities of epigeic beetles in cultural landscape. Since the research was always carried out on a farmed landscape, the impact of surrounding landscape on gained results is minimal and insignificant.

The exotic cabbage maggot (CM) infests canola on the prairies, feeding on roots in its larval stage, which disrupts the uptake of nutrients and water and provides an entry point for fungal plant pathogens. The European staphylinid, Aleochara bipustulata L., may be introduced for control of CM, but only if the risk to other species is low and if A. bipustulata has demonstrable potential to increase mortality already caused by natural enemies in Canada. Aleochara bipustulata could contribute to pest management as a predator of CM eggs and larvae, and as a parasitoid of CM puparia; however, it could affect non-pest species in the same two ways. A variety of invertebrates that share the soil of Brassica fields with immature CM were screened in laboratory no-choice assays to determine what adult A. bipustulata eat. In these assays, immobile or barely mobile invertebrates were accepted regularly and could be at risk. The majority of groups were seldom or never consumed. Also, a molecular assay developed to test for CM DNA in the guts of field-collected A. bipustulata revealed its high potential as a predator, and a similar assay developed for two carabid beetle species showed these to be seldom if ever consumed. Laboratory and field cage assays with other CM egg predators showed A. bipustulata has potential to disrupt other species, particularly the closely related A. bilineata Gyllenhal, as they seem to forage in similar microhabitats. Measurements of field-collected beetles indicate CM is unlikely to be the primary host in Europe, so introducing A. bipustulata to Canada may bring risks to non-target Diptera species. This was observed even though a series of laboratory experiments demonstrated CM is a superior and preferred host relative to the smaller, acalyptrate cheese skipper.

Aleochara bilineata and Aleochara bipustulata are staphylinid beetles that are attracted to pitfall traps baited with dimethyl disulphide (DMDS), but the role of DMDS in their biology has not been elucidated. In still air, first instar larvae of both Aleochara species exhibited area-restricted movement when they came near to DMDS. DMDS increased the frequency of parasitism of D. radicum puparia, the preferred host, but the frequency of attacks on unpreferred piophilid puparia was not affected by DMDS. In still air, adult A. bilineata and A. bipustulata distribution was not consistently influenced by DMDS. In a Y-tube olfactometer, newly-emerged females of both species avoided DMDS-laden air; after 10 days mated females chose air with DMDS. Newly emerged males also avoided DMDS, but after 10 days mated males neither avoided nor selected DMDS-laden air: the shift in response was associated with mating status rather than age.

Full textAbstract:
There is very low tolerance for blueberry maggot (Rhagoletis mendax Curran) in blueberries making it a serious pest in eastern North America. Control is focused on eliminating flies with insecticides before oviposition in fruit. Organic mulches may improve highbush blueberry production, but their effects on this pest are largely unknown. The research in this thesis evaluated compost and pine needle mulches on blueberry maggot (mature maggots, pupae, emerging flies) and predatory beetles that may consume these stages.
Mulches affected fly emergence and maggot pupation. Fly emergence was reduced by 80-100% and delayed ~8 days from pupae covered with 20 cm of pine needles compared to 1 cm of soil. Emergence from 20 cm of compost was lower in wet conditions, and 5 cm of mulch did not limit emergence in the field. Pupation at increased depth reduced emergence because flies did not eclose or, if eclosed, were unable to crawl to the surface. The delay was likely due to lower temperatures at depth. No flies emerged from 1 cm in pine needles in the field probably due to high temperatures. In the laboratory, maggots pupated more deeply in pine needles than other substrates, but ~30% did not pupate in dry pine needles. Saturated soil caused ~50% of maggots to pupate on the surface.
Mulching altered beetle diversity and activity/density and affected beetle predation on maggots and pupae. Compost plots in a highbush blueberry field attracted predatory carabids and staphylinids, although some staphylinids were frequent in pine needles and phytophagous carabids preferred unweeded compost plots. Attraction to compost, particularly for Pterostichus melanarius (Illiger), was due primarily to higher prey densities - earthworms and millipedes - than other treatments. This beetle consumed some maggots or pupae in soil or compost, but predation rates decreased when alternative prey was abundant.
Blueberry bushes in weedy compost plots attracted many flies, but infestation rates were higher in composted bushes only in the year mulch was applied. Overall, thick mulching with pine needles contributes most significantly to blueberry maggot management. Future research should explore integration of mulch with other tactics for R. mendax control.

The aim of the work was to study the communities of epigeic beetles in plantations of energetic plants (Dactylis glomerata, Arrhenatherum elatius, Phalaris arundinacea, Helianthus tuberosus) and in surrounding lawn biotope. The method of pitfall trapping was used for beetle sampling from 2008 to 2010 during the growing season. Carabid beetles (Carabidae) and rove beetles (Staphylinidae) were used as bioindicators. In total 69 species and 1789 individuals were captured and evaluated. Eurytopic species were more common than stenotopic in all habitats, also the value of the index of beetle communities was low in all plots. RDA analysis proved the influence of surrounding biotope on beetle communities. It was concluded that communities of epigeic beetles might be also affected by the climatic factors, long termed population fluctuations of individual species, edge effect and microclimate inside the vegetation.

Rove beetles (Staphylinidae) in Ontario soybean-hedgerow agroecosystems were surveyed in 2009-2010 to identify common, widespread species and assess their potential biological control of Soybean Aphid and Bean Leaf Beetle. The spatiotemporal distributions, habitat use, and co-occurrence of staphylinids with soybean pests were studied to provide a framework for future agroecological studies of biocontrol services in soybean. A taxonomic review of the Staphylinina (Staphylinidae: Staphylininae) (‘large rove beetles’) for the geographic area of study was conducted and identification keys were created to assist in future staphylinid research. Common soybean staphylinids were generally exotic, penetrated field interiors, utilized hedgerow habitat outside the growing season and co-occurred with pest populations during vulnerable life stages. Several species exhibited nocturnal activity in soybean foliage. Biocontrol of overwintering Soybean Aphid and Bean Leaf Beetle populations in hedgerows by staphylinids may occur in buckthorn canopies and leaf litter, respectively.

Full textAbstract:
碩士<br>國立臺灣大學<br>昆蟲學研究所<br>99<br>The estimation of postmortem interval (PMI) is one of the most important issues in forensic entomology, and estimating the developmental time of the immature stages of necrophagous flies, especially blow flies, has been the main tool to estimate PMI. Many parasitic insects may alter the development of immature stages of flies, and thus affecting the PMI estimation. For most species of the rove beetle genus Aleochara which have been studied, their larvae are ectoparasitoids of the pupae of cyclorrhapha flies. Among them, some species that parasitize necrophagous flies may have forensic importance. I studied two Aleochara species in Taiwan that visit carrion site, A. nigra and A. formosanorum. The results of field survey conducted in northern Taiwan show that they are commonly found in northern Taiwan. All the five necrophagous (Hemipyrellia ligurriens, Lucilia cuprina, Chrysomya megacephala, C. rufifacies, sarcophagid sp.) and one non-necrophagous fly species (Bactrocera dorsalis) I examined have the potential to be parasitized by some individuals of these two Aleochara species, but differences among the acceptance and suitability of the rove beetle larvae to these host species suggest that rove beetles may prefer specific hosts. Each stage of their life history under 3 different temperatures has been recorded for estimating the developmental time under different temperatures. The larval stage together with the pupal stage of both species are longer than the pupal stages of their hosts, implying their potential usage of elongating the PMI estimation in forensic investigation. In addition, the host weight and the duration of the larval stage of A. formosanorum are positively correlated, thus it should be considered while applying the parasitized fly pupae in PMI estimation.

Aleochara bipustulata, a European natural enemy of Delia radicum, shows promise as a biological control agent in Canadian canola. Post-diapause development of D. radicum and Aleochara bilineata was studied in the laboratory. Prairie D. radicum developed more slowly than from Ontario, suggesting particular source populations of A. bipustulata may be better suited to western Canada than others. Aleochara bilineata develops too slowly for effective predation of early immature D. radicum. Aleochara bipustulata's host range was studied in the laboratory and its habitat associations studied in Europe. Beneficial Diptera species were either unsuitable hosts, or for Lonchaea corticis found in habitats not visited by A. bipuslulata. Suitable laboratory host species were relatively small or closely related to D. radicum. Species with unusual puparia were less likely to be accepted as hosts than D. radicum. Species which develop quickly in the pupal stage. or with relatively heavy puparia, were unsuitable hosts.
