Introduction: Les Arthropodes sont vecteurs de nombreuses maladies chez les hommes, les animaux et les plantes. Cest pourquoi lidentification des vecteurs devient necessaire afin de mener une lutte a travers des programmes nationaux de lutte. Methodes: Cette etude a ete conduite dans trois differentes zones eco-climatiques du Mali afin de voir la variation saisonniere des Arthropodes dinteret medical, veterinaire et Agricole au Mali. La collecte des arthropodes a ete faite a laide de deux types de piege (Piege demergence et piege en T) dans les villages de Bia, de Kenieroba et de Thierola. Les identifications ont ete faites a la loupe pour les Arthropodes, et par PCR pour les moustiques. Limportance des Arthropodes collectes a ete evaluee a travers leur dominance et leur frequence en fonction des zones et des saisons. Resultats: Letude des arthropodes des trois zones a permis davoir un apercu de lensemble de variations qualitatives et quantitatives des differents Arthropodes. Un total de 20 especes dArthropodes appartenant a trois classes a ete identifie (Arachnides, Insectes Myriapodes), 13 ordres (Araneides, Coleopteres, Dermapteres, Dictyopteres, Dipteres, Hemipteres, Hymenopteres, Lepidopteres, Nevropteres, Odonates, Orthopteres, Plecopteres, Trichopteres). Les Dipteres sont mieux representes a Bia et a Thierola et les Coleopteres frequents a Kenieroba. Conclusion: Il ressort de cette etude que les Arthropodes etaient plus frequents pendant la saison des pluies sur les sites. Les Arthropodes dinteret agricole constituaient le groupe dominant sur chacun des sites, suivi de ceux dinteret medical.

Abstrak. Arthropoda permukaan tanah merupakan kelompok hewan yang sebagian atau seluruh daur hidupnya berada di permukaan tanah, sehingga dapat dijadikan sebagai bioindikator lingkungan terutama dalam penentuan kualitas tanah. Keberadaan arthropoda permukaan tanah dalam suatu agroekosistem dipengaruhi oleh kondisi habitat, seperti iklim, ketebalan serasah, kandungan bahan organik, kesuburan tanah, jenis tanah, tekstur dan struktur tanah serta keanekaragaman vegetasi yang ada dalam agroekosistem tersebut. Arthropoda permukaan tanah dalam suatu agroekosistem memiliki beberapa peranan penting antara lain sebagai dekomposer, detritivor, predator, dan herbivor. Penelitian ini menggunakan metode deskriptif dengan pengambilan sampel arthropoda permukaan tanah menggunakan perangkap pitfall trap. Peubah yang diamati meliputi komposisi, kelimpahan, indeks keanekaragaman, indeks kemerataan, indeks dominasi dan indeks similaritas arthropoda permukaan tanah. Hasil penelitian menunjukkan bahwa, arthropoda permukaan tanah yang ditemukan pada lahan pertanaman tembakau di Desa Keunaloi terdapat 49 morfospesies dengan total individu 3720, sedangkan di Desa Lamkleng terdapat 45 morfospesies dengan total individu 536. Morfospesies arthropoda permukaan tanah yang paling melimpah di Desa Keunaloi adalah semut Solenopsis geminata sedangkan di Desa Lamkleng yaitu semut Nylanderia sp1. Nilai indeks keanekaragaman arthropoda permukaan tanah yang termasuk kategori stabil terdapat di Desa Lamkleng yaitu 2,88. Nilai indeks kemerataan arthropoda permukaan tanah yang termasuk kategori lebih stabil terdapat di Desa Lamkleng yaitu 0,76. Nilai indeks dominasi arthropoda permukaan tanah tertinggi terdapat di Desa Keunaloi yaitu 0,76 termasuk kategori tidak stabil. Nilai indeks similaritas pada kedua lahan pertanaman tembakau yaitu 0,61 termasuk kategori lebih stabil. Semakin tinggi tingkat keanekeragaman morfospesies arthropoda permukaan tanah maka tingkat kestabilannya semakin tinggi, pada penelitian ini agroekosistem di Desa Lamkleng lebih stabil di bandingkan di Desa Keunaloi.Comparison of Soil Surface Arthropod Diversity in Two Different Tobacco Ecosystem Sites in Aceh Besar DistrictAbstract. Soil surface arthropods are a group of animals that partially or completely live on the soil surface, so they can be used as environmental bioindicators, especially in determining soil quality. The presence of soil surface arthropods in an agroecosystem is influenced by habitat conditions, such as climate, litter thickness, organic matter content, soil fertility, soil type, soil texture and structure and vegetation diversity in the agroecosystem. Soil surface arthropods in an agroecosystem have several important roles, including as decomposers, detritivors, predators, and herbivores. This study used descriptive method by sampling soil surface arthropods using pitfall traps. The observed variables include composition, abundance, diversity index, evenness index, dominance index and similarity index of soil surface arthropods. The results showed that there were 49 morphospecies of soil surface arthropods found on tobacco plantations in Keunaloi Village with a total of 3720 individuals, while in Lamkleng Village there were 45 morphospecies with a total of 536 individuals. The most abundant soil surface arthropod morphospecies in Keunaloi Village was Solenopsis geminata ants while in Lamkleng Village it was Nylanderia sp1 ants. The index value of soil surface arthropod diversity which is included in the stable category is in lamkleng village, namely 2.88. The value of the land surface arthropod evenness index which is included in the more stable category is in lamkleng village which is 0.76. The highest soil surface arthropod dominance index value is in keunaloi village which is 0.76 including the unstable category. The similarity index value in both tobacco growing land is 0.61, which is categorized as more stable. The higher the level of diversity of soil surface arthropod morphospecies, the higher the level of stability, in this study the agroecosystem in Lamkleng Village is more stable than in Keunaloi Village.

Les arthropodes ravageurs des cultures constituent une menace permanente pour la production horticole. La plupart des familles d’arthropode sont très mal connues dans la zone agroécologique de la Casamance car peu de travaux de recherches ont été effectués. Une meilleure connaissance des ravageurs facilite le choix des stratégies de lutte. L’objectif de cette étude est de déterminer l’occurrence et la diversité spécifique des ravageurs associés aux cultures maraîchères. Une étude a été menée sur 144 parcelles situées dans trois localités de la zone agroécologique de la Casamance. L’inventaire des arthropodes ravageurs des cultures a été effectué dans les périmètres maraîchers. Des indices écologiques sont calculés pour évaluer diversité des ravageurs. Un nombre de 4882 spécimens de ravageurs dont 65 espèces réparties dans sept ordres et 28 familles sont collectés sur 17 plantes hôtes. Quatre ordres de ravageurs attaquent la moitié des plantes hôtes échantillonnées. Un total de 51 espèces a une présence de 100%. La diversité des ravageurs est plus élevée à Oussouye alors que l’abondance est plus élevée à Ziguinchor. La connaissance de la diversité et de la distribution des ravageurs facilitent la mise en place de stratégies alternatives de lutte en vue de préserver la filière maraîchère.
Arthropod pests of crops are a permanent threat to horticultural production. Most arthropod families are poorly known in the Casamance agroecological zone because little research has been done. A better knowledge of the pests facilitates the choice of control strategies. The objective of this study is to determine the occurrence and specific diversity of pests associated with crops. A study was conducted on 144 plots located in three localities of the Casamance agroecological zone. The inventory of crop pests were carried out in the market gardens. Ecological indices were calculated to assess pest diversity. A total of 4882 pest specimens including 65 species in seven orders and 28 families were collected from 17 host plants. Four orders of pests attacked half of the sampled host plants. A total of 51 species have a 100% occurrence. Pest diversity is higher in Oussouye, while abundance is higher in Ziguinchor. Knowledge of the diversity and distribution of pests facilitates the development of alternative control strategies to preserve the market gardening sector.

Full textAbstract:
Carvacrol is an active ingredient of essential oils from different plants, mainly from oregano and thyme species. It poseses biocidal activity agains many artropodes of the importance for veterinary and human medicine. Carvacrol acts as repelent, larvicide, insecticide and acaricide. It acts against pest artropodes such as those that serve as mechanical or biological vectors for many causal agents of viral, bacterial and parasitic diseases for animals and humans. Therefore, it may be used not only in pest arthropodes control but in vector borne diseases control, too. In the paper carvacrol bioactivity against mosquitoes, house flies, cockroaches, ticks and mites are described. Potencial modes of carvacrol action on artropodes are given, too. Carvacrol reachs its biotoxicity against arthropodes alone or in combination with other active ingredients from the same plant of its origin, such as tymol, cymen or others. The paper explains reasons for frequently investigations on essential oils and other natural products of plant origin to their biotoxicity against food stored pest or pest of medicinal importance, as well as, needs for their use in agriculture, veterinary and human medicine.

Diversity of understory arthropods in the dry forests of Madagascar. The arthropods of Madagascar are among the most poorly known animal groups on the island. The principal objective of this study was to determine the diversity of this group at three different localities in lowland dry forests of western Madagascar. The three sites, all inventoried during the dry season in 2017, include: the Ankarafantsika National Park (16°18’S, annual rainfall: 867 mm) in the northwest; the forest of the Centre National de Formation, d’Études et de Recherches en Environnement et Forestier (CNFEREF) at Kirindy (20°04’S, annual rainfall: 555 mm) in the central west; and the Tsimanampesotse National Park (24°01’S, annual rainfall: 334 mm) in the extreme southwest. Malaise and pit-fall traps were used to capture arthropods and 24 orders belonging to 133 families were identified. The community at Ankarafantsika was the most diverse with 19 orders and 89 families with a more balanced taxonomic representation, while Tsimanampesotse had 18 orders and 69 families and Kirindy CNFEREF had 17 orders and 70 families. Calculated similarity between the different sites at the family level was relatively high, while that at the order level relatively low even given a certain level of homogeneity was noted between the three localities. The composition of arthropods in the dry forests of Madagascar varies according to local conditions, which include bioclimatic factors, and the characteristics of the vegetation at the three localities.

Abstrak. Arthropoda merupakan filum yang paling dominan di antara filum hewan lainnya jika ditinjau dari keanekaragaman, penyebaran, dan jumlah spesiesnya. Pada pertanaman kopi arabika terdapat arthropoda yang berperan sebagai herbivor, musuh alami, serangga penyerbuk, serangga netral, dan dekomposer. Secara umum, tindakan pengelolaan yang dilakukan oleh petani pada pertanaman kopi di Desa Atang Jungket Kabupaten Aceh Tengah adalah dengan menggunakan pestisida sintetik tanpa mempedulikan kondisi agroekosistemnya. Supaya agroekosistem kopi tetap stabil dan berkelanjutan, maka perlu dilakukan tindakan pengelolaan yang ramah lingkungan yaitu dengan menggunakan perangkap warna dimana proses penemuan inang serangga didasari oleh faktor visual yang bertujuan untuk mengetahui warna perangkap yang disukai oleh arthropoda pada areal pertanaman kopi arabika. Pada penelitian ini digunakan metode purposive sampling (ditetapkan) dengan luas lahan 5.000 yang berjumlah 138 tanaman, kemudian dibagi menjadi empat petak secara berjajar. Setiap petak diambil 20 tanaman sampel dengan menggunakan perangkap warna merah, kuning, hijau, dan putih. Peubah yang diamati meliputi komposisi dan kelimpahan arthropoda berdasarkan warna perangkap, indeks similaritas famili antar warna perangkap, serta kepadatan relatif Famili Scolytidae. Hasil penelitian menunjukkan bahwa arthropoda yang ditemukan berjumlah 2.062 individu yang terdiri dari 2 kelas, 12 ordo, dan 72 famili. Ordo Hymenoptera merupakan ordo dengan jumlah individu paling banyak. Perangkap warna kuning merupakan paling banyak memerangkap arthropoda yaitu 552 individu dibandingkan perangkap warna merah, hijau, dan putih yang masing-masingnya hanya 547 individu, 527 individu, dan 436 individu. Nilai indeks similaritas famili arthropoda antar warna perangkap tergolong rendah berarti keragaman famili yang menyusun komunitas tersebut tinggi. Kepadatan Famili Scolytidae berjumlah 0,02 individu/m2 dan kepadatan relatif 0,04%. Hal ini menunjukkan bahwa pengelolaan tanah dan tanamannya secara ekologis masih menguntungkan, tidak mengancam keberlangsungan budi daya tanaman.Preference of Arthropod to Color of Trap on Arabica Coffee Plantation in Atang Jungket Village Aceh Tengah DistrictAbstract. Arthropods are the most dominant phylum among other animal phyla when viewed from the diversity, distribution, and number of species. In arabica coffee plantation there arthropods that act as herbivor, natural enemies, pollinating insects, neutral insects, and decomposers. In general, the management actions carried out by farmers on coffee plantations in Atang Jungket Village, Central Aceh District is to use synthetic pesticides regardless of agro-ecosystem condition. For coffee agro-ecosystem to remain stable and sustainable, it is necessary to do an environmentally friendly management action that is by using color trap where the process of invention of insect host is based on visual factor which aim to know color of trap were liked by arthropod in arabica coffee plantation area. This research uses purposive sampling method with 5,000 land area of 138 plants, then divided into four plots in a row. Each plot was taken 20 sample plants using red, yellow, green, and white traps. The observed variables include the composition and abundance of arthropods based on the trap color, the family similarity index between the trap colors, and the relative density of the Scolytidae Family. The results showed that the arthropods were 2,062 individuals consisting of 2 classes, 12 orders, and 72 families. The Hymenoptera Order is the order of the largest number of individuals. The yellow trap is the most arthropod trap of 552 individuals compared to the red, green, and white traps of 547 individuals, 527 individuals and 436 individuals each. The value of the arthropod family similarity index between the trap colors is low, meaning that the diversity of families that make up the community is high. The Scolytidae Family density was 0.02 individuals/m2 and the relative density was 0.04%. This indicates that the management of land and plants are ecologically still profitable, not threatening the sustainability of cultivation of crops.

Full textAbstract:
Extant arthropods are diverse and ubiquitous, forming a major constituent of most modern ecosystems. Evidence from early Palaeozoic Konservat Lagerstätten indicates that this has been the case since the Cambrian. Despite this, the details of arthropod origins remain obscure, although most hypotheses regard the first arthropods as benthic predators or scavengers such as the fuxianhuiids or megacheirans (‘great-appendage’ arthropods). Here, we describe a new arthropod from the Tulip Beds locality of the Burgess Shale Formation (Cambrian, series 3, stage 5) that possesses a weakly sclerotized thorax with filamentous appendages, encased in a bivalved carapace, and a strongly sclerotized, elongate abdomen and telson. A cladistic analysis resolved this taxon as the basal-most member of a paraphyletic grade of nekto-benthic forms with bivalved carapaces. This grade occurs at the base of Arthropoda (panarthropods with arthropodized trunk limbs) and suggests that arthrodization (sclerotization and jointing of the exoskeleton) evolved to facilitate swimming . Predatory and fully benthic habits evolved later in the euarthropod stem-lineage and are plesiomorphically retained in pycnogonids (sea spiders) and euchelicerates (horseshoe crabs and arachnids).

Species diversity is a community level characteristic based on species abundance which can be used to describe community structure. Arthropoda is the largest phylum of the animalia kingdom and the number of species in Arthropoda is more than all the species from other phyla. This research is a descriptive explorative research. The aim is to determine the level of diversity and abundance of arthropods in shallot farming land in an effort to prepare ecological practical guidelines. Arthropod species catching technique uses the pitfall trap method. The results of this study were found to be 4 species of arthropods from two classes with a total number of 47 individuals found. The index of diversity of arthropods in shallot farming was low (H' < 3) and the analysis of the abundance index of one species of arthropods had a high abundance index, while the other two species had a moderate abundance index and one species had a low abundance index. The types of arthropods found on shallot farms are: 1) Spodoptera exigua L.; 2) Valanga sp.; 3) Lilioceri L.; and 4) Pass sp. The results of the validation by a team of expert validators and the readability test by 20 students concluded that they did not need revision (80% were in the good category and were suitable for use).

L'inventaire des ectoparasites des petits ruminants nécessite une mise à jour. Il semble cependant qu'aux Antilles la tique Amblyomma variegatum et en Guyane les taons et les diptères myiasigènes soient les arthropodes les plus néfastes à l'élevage. Des précautions doivent être prises pour éviter le transfert d'A. variegatum vers les îles saines des Antilles (Saintes, St-Barthélémy) et vers le continent (Guyane). Dans les zones infestées, une lutte systématique doit être menée par administration régulière d'acaricides aux petits ruminants comme aux bovins.

The soil arthropod diversity is influenced by the season rather than the plantation age. Arthropods will respond to every aberration from normal environmental conditions, against high or low temperature thresholds to respond in many ways. The study was carried out in Mangli coffee plantation Kediri regency to determine the effect of season on the abundance and diversity of soil arthropods. In each season is an installed systematically 30 pitfall traps. The environmental factors as measured where the temperature and humidity of soil, soil organic carbon, soil organic matter, N, P and K. The soil arthropods abundance was analyzed using PCA. The soil arthropod diversity was analyzed using Shannon index, dominance and equitability. The environmental factor effect on the soil arthropod abundance was analyzed using CCA. The season is very effect on the soil arthropod abundance in Mangli coffee plantation. The Myrmica genus is very abundant in the dry season while in rainy season is Entomobrya genus. Based on PCA result, the dry season is characterized by Ponera genus while the rainy season is characterized by Entomobrya and Neoponera genus. The soil arthropod diversity in rainy season is higher than the dry season. The taxa number, individual number, Shannon diversity index and equitability in the rainy season are higher than the dry season. The most of environmental factors of Mangli coffee plantation in dry season except temperature and phosphor are higher than rainy season. Based on CCA can be known that temperature and phosphor influence the distribution of most soil arthropods in rainy season. Â

Elles ont joué un rôle majeur dans l’émergence des formes de vie et dans la diversification des organismes. Les symbioses se retrouvent dans toutes les branches du vivant impliquant des virus, des bactéries ou des cellules eucaryotes (Moran et al. 2006). Les symbioses sont aujourd’hui connues chez de nombreux organismes. Elles sont très bien décrites chez les arthropodes, principalement les symbioses bactériennes, notamment chez les insectes, puisque 15% des espèces d'insectes vivraient en association avec des symbiotes bactériens intracellulaires.

Full textAbstract:
Arthropods are hummingbirds’ principal source of nitrogen, fatty acids, and micronutrients. Despite the nutritional importance of arthropods for hummingbirds, our understanding of the factors influencing their consumption and their relative role as an energy source remains limited. Here, we aimed to describe the use of arthropods by a hummingbird ensemble in a seasonal temperate mountain ecosystem in West Mexico during one annual cycle. We compared arthropod capture attempt rates among six different humming species. Also, we investigated the impact of seasonal variation in food availability on the arthropod capture attempt rates of the White-eared Hummingbird (Basilinna leucotis), the sole species observed foraging for arthropods in all seasons. We found that hummingbirds ingested arthropods from different orders (Araneae, Hemiptera, Psocoptera, Hymenoptera, and Diptera), with arthropod capture attempt rates varying wildly among species. The arthropod capture attempt rates of the White-eared Hummingbird showed a significant positive correlation with arthropod availability, peaking during the warm-dry season when floral nectar was scarce and arthropod availability was high. Our data show that arthropod ingestion is crucial for some hummingbird species, mainly when nectar availability is limited or absent in the environment.

Sur un échantillon de 657 animaux examinés, 524 étaient porteurs de parasites, soit un taux global d’infestation de 79,8 p. 100. Treize espèces ont été identifiées : Cnemidocoptes mutans, Epidermoptes bilobatus, Dermanyssus gallinae, Hyalomma rufipes, Amblyomma variegatum, Argas persicus et Haemaphysalis hoodi pour les acariens ; Menopon gallinae, Menacanthus stramineus, Lipeurus caponis, Goniodes meleagridis, Goniocotes gallinae et Echidnophaga gallinacea pour les insectes. Les résultats ont montré que la prévalence du parasitisme due aux insectes était significativement plus élevée que celle due aux acariens (p < 0,05). Les acariens fixés à la peau étaient répartis sur tout le corps des oiseaux, tandis que les insectes étaient observés sur le plumage et le corps. Le taux d’infestation a été plus élevé pendant la période humide de l’étude (p < 0,05). La prévalence du parasitisme a augmenté significativement avec l’âge des oiseaux (p < 0,05). Menacanthus stramineus a été le parasite présentant la prévalence la plus élevée. Cette situation, liée au mode traditionnel de l’élevage pratiqué dans cette région du Bénin, laisse envisager des mesures de lutte associant les traitements antiparasitaires des oiseaux à l’hygiène de l’habitat et de l’alimentation.

Full textAbstract:
Since the late Paleozoic, insects and arachnids have diversified in the terrestrial world so spectacularly that they have become unquestionably the most diverse group of organisms to ever inhabit the planet. In fact, this 300 million year interval may appropriately be referred to as the age of arthropods. What is the origin and history of terrestrial arthropods? How is arthropod diversity maintained on land? In this rhetorical context we will discuss (1) the degree to which terrestriality is found in arthropods, (2) the physiological barriers to terrestrialization that arthropod clades confronted, (3) the historical record of arthropod diversity on land based on paleobiological, comparative physiological and zoogeographical evidence, and (4) some tentative answers to the “why” of terrestrial arthropod success. We are providing a geochronologic scope to terrestriality that includes not only the early history of terrestrial arthropods, but also the subsequent expansion of arthropods into major terrestrial habitats.

Les châtaigneraies à fruits sont des milieux créés et entretenus par l’homme depuis leur introduction il y a quelque 2000 ans. Sans entretien régulier, elles sont vouées à disparaître, ce qui aurait des effets négatifs sur le paysage et la biodiversité. Afin de mieux comprendre ces processus, des études comparatives sur les chauves-souris, les oiseaux, les lichens et les arthropodes ont été réalisées dans des châtaigneraies entretenues et abandonnées. Tous les taxons et tout particulièrement les espèces rares et menacées profitent de l’entretien des châtaigneraies. La restauration de ces dernières est donc indispensable pour la conservation à long terme d’un paysage agro-forestier comportant des arbres-habitats séculaires de grande valeur écologique.

Full textAbstract:
The abundance of arthropods is declining globally, and human-modification of natural habitat is a primary driver of these declines. Arthropod declines are concerning because arthropods mediate critical ecosystem functions, and sustained declines may lead to cascading trophic effects. There is growing evidence that properly managed urban environments can provide refugium to arthropods, but few cities have examined arthropods within urban greenspaces to evaluate their management efforts. In this study, we surveyed arthropod communities within a medium-sized, growing city. We investigated arthropod communities (abundance, richness, diversity, community composition) within 16 urban greenspaces across metropolitan Grand Rapids, Michigan (USA). We focused our efforts on urban gardens and pocket prairies, and measured environmental variables at each site. We collected 5,468 individual arthropods that spanned 14 taxonomic orders and 66 morphospecies. The results showed that community composition was influenced by impervious surface, white flower abundance, and humidity. Total arthropod abundance and diversity were positively associated with humidity. For specific orders, Hymenoptera (bees, ants, wasps) abundance was negatively associated with temperature, and positively associated with site perimeter-area ratio. Hemiptera (true bugs) were negatively associated with impervious surface and positively associated with humidity. These findings show that impervious surfaces impact arthropod communities, but many of the observed changes were driven by local abiotic conditions like temperature and humidity. This suggests that management decisions within urban greenspaces are important in determining the structure of arthropod communities. Future studies on arthropods in cities should determine whether manipulating the abiotic conditions of urban greenspaces influences the composition of arthropod communities. These results should inform city planners and homeowners of the need to properly manage urban greenspaces in cities to maintain diverse arthropod assemblages.

AbstractCultivating plant mixtures is expected to provide a higher productivity and a better control of pests and diseases. The structure of the arthropod community is a major driver of the magnitude of natural pest regulations.With the aim of optimizing pest management, a study was carried out to determine the effect of the cropping system type (tomato mono-cropping vs. mixed-cropping) on the diversity and abundance of arthropods from three trophic groups (herbivores, omnivores, predators) and the abundance of Helicoverpa armigera. Therefore, the diversity of cultivated plants and arthropod communities was assessed within tomato fields from 30 farmer's fields randomly selected in South of Benin. Results showed that the arthropod abundance was significantly higher in mixed-cropping systems compared with mono-cropping systems, although the crop type did not alter significantly the arthropod diversity, evenness, and richness. At the level of taxa, the abundances of generalist predators including ants (Pheidole spp., and Paltothyreus tarsatus) and spiders (Araneus spp. and Erigone sp.) were significantly higher in mixed fields than in mono-crop fields. Then, the abundances of omnivore-predator trophic groups have a negative significant effect on the H. armigera abundance. This study allowed better understanding of how plant diversity associated to tomato fields structures arthropod's food webs to finally enhance the ecological management of H. armigera.

Nutmeg (Myristica fragrans Hout) is a leading commodity from Aceh Province. The high yield of nutmeg oil and its distinctive aroma makes it in demand by the world market. The production of nutmeg plants is currently decreasing due to the disturbance of nuisance organisms so that nutmeg plants get sick and die. Appropriate agro eco-management of the nutmeg system is thought to overcome these problems. Such as by conserving the diversity of arthropod communities. Information regarding the presence of arthropods in nutmeg cultivation is very limited in South Aceh District. This study investigates the abundance of arthropods in nutmeg cultivation in different vegetation to detect the causes of the decline in nutmeg production in the South Aceh district. Sampling was carried out at 2 locations with different vegetation conditions, using the determining sub-samples. Each location consisted of 200 individual nutmeg plants, and at each location, several 20 individual nutmeg plants were assigned as samples. The results showed that the total collection of arthropod populations at the location I found nine orders, namely Araneae, Coleoptera, Dermaptera, Diptera, Homoptera, Hemiptera, Hymenoptera, Isoptera, and Orthoptera. Location II found 12 orders, namely Araneae, Blattodea, Coleoptera, Dermaptera, Diptera, Embioptera, Homoptera, Hemiptera, Hymenoptera, Isoptera, Orthoptera, and Phasmatodea). The class of insects and arachnids found at these two locations is part of the Phylum Arthropoda.

Full textAbstract:
Abstract Arthropods can provide a valuable source of protein for many vertebrate and invertebrate consumers. Yet, not all protein in an arthropod may be equally digestible to consumers. Arthropods are defined by their exoskeleton, which is a mixture of chitin and protein that is largely indigestible to most consumers. I will discuss how exoskeleton complicates the measure of arthropod protein content for insectivores. Arthropod taxa vary widely in exoskeleton content from about 10 to 40 % of their dry mass. Exoskeleton also varies in amino acid content from about 6 to 70 % of its dry mass. When spiders feed on arthropods, they extract nearly all of the soft tissue and leave behind the exoskeleton as prey remains. This complicates the measurement of digestible protein content of arthropod prey as one of the most common methods, crude protein, does not distinguish between exoskeleton and soft tissue. Instead, our results show that some spectrophotometric methods are more accurate measures of digestible protein in arthropods, especially if solvents like NaOH are used to prepare samples. Finally, proteins are an important source of nitrogen for insectivores. Using feeding experiments, we showed that measures of digestible (i.e., non-exoskeleton) nitrogen content of arthropods are a more accurate measure of what a spider consumes than is the whole nitrogen content of an arthropod body. Hence, while exoskeleton complicates the measure of arthropod protein content, there are ways to correct for exoskeleton to get more accurate measures of the quality of arthropods as prey for insectivores.

Full textAbstract:
Plant-resident arthropods are closely tied to the distribution of their hosts across multiple spatial scales. Shrubs provide habitat for a range of arthropods, and variations within shrubland ecosystems may affect arthropod communities. We examined the role of shrub species and density in structuring arthropod communities in an encroached Australian woodland using two common and widespread shrub species, Turpentine (Eremophila sturtii) and Silver Cassia (Senna artemisioides subsp. filifolia). We found five times more arthropods (Psocoptera, Collembola and Hemiptera) on Eremophila compared with Senna. Furthermore, Psyllidae were found only on Eremophila. In total we recorded 39 Hemipteran species; 13 from Eremophila, 16 from Senna and 10 common to both shrub species. Each shrub species supported a unique arthropod assemblage, even though they grow in close proximity (<15 m). In contrast, we found limited effects of fine-scale plant density, with plants growing in low and high density supporting similar arthropod communities. Our study indicated that isolated shrubs in these woodlands support a variety of arthropods, and shrub species is a more important driver of arthropod community structure than fine-scale density.

Full textAbstract:
Transposable elements (TEs) are ubiquitous in arthropods. However, analyses of large-scale and long-term coevolution between TEs and host genomes remain scarce in arthropods. Here, we choose 14 representative Arthropoda species from eight orders spanning more than 500 million years of evolution. By developing an unbiased TE annotation pipeline, we obtained 87 to 2266 TE reference sequences in a species, which is a considerable improvement compared to the reference TEs previously annotated in Repbase. We find that TE loads are diversified among species and were previously underestimated. The highly species- and time-specific expansions and contractions, and intraspecific sequence diversification are the leading driver of long terminal repeat (LTR) dynamics in Lepidoptera. Terminal inverted repeats (TIRs) proliferated substantially in five species with large genomes. A phylogenetic comparison reveals that the loads of multiple TE subfamilies are positively correlated with genome sizes. We also identified a few horizontally transferred TE candidates across nine species. In addition, we set up the Arthropod Transposable Elements database (ArTEdb) to provide TE references and annotations. Collectively, our results provide high-quality TE references and uncover that TE loads and expansion histories vary greatly among arthropods, which implies that TEs are an important driving force shaping the evolution of genomes through gain and loss.

Full textAbstract:
SUMMARY We have examined the gas-exchange characteristics of five southern African centipede species from three orders. Two scolopendromorph species exhibit discontinuous gas-exchange cycles (DGCs) identical to those recorded for several insect and chelicerate species. Another scolopendromorph and a lithobiomorph species exhibit weak periodic patterns, and a scutigermorph species shows continuous gas exchange. A crucial component for DGCs in tracheated arthropods is the presence of occludible spiracles. However, on the basis of studies of temperate centipedes, most recent invertebrate biology texts hold the view that centipedes, as a group, cannot close their spiracles. Using flow-through normoxic and normoxic—anoxic—normoxic respirometry and electron microscopy, we conclusively demonstrate that at least one of the scolopendromorph species, Cormocephalus morsitansL., can close its spiracles fully, thus accounting for its DGCs. Homologies in spiracular structure and DGCs suggest that several other tracheated arthropod taxa probably have this ability too and that DGCs have evolved convergently at least four times in the Arthropoda. Spiracular closure and discontinuous gas-exchange cycles are probably more widespread in arthropods than has previously been suspected.

<p>The trap crop technique relies on the attraction of insect pests to plantings other than the main crop. Application using of lemon grass for Habitat modification on paddy field can alter species composition and community structure including Arthropods from insect groups. The lemon grass was planted 20 day before main crop (paddy variety IR 64). This study was conducted in Pasuruan, East Java. Samples were taken using sweep net on vegetative paddy phase, generative paddy phase and ripening paddy phase. Sampling periods from Desember 2012 to March 2013. Each sample was sorted and identified to the family and morphospecies or species. Samples are identified in Zoological laboratory on department of biology, ITS. Study on Arthropoda diversity at different habitats by comparing the species richness is useful for determining ecological indicators at each habitat. The arthropods caught were then classified into some classes: pest (herbivore), natural enemy (parasitoid and predator), and other arthropods. After that, the Species Diversity Index was determined using its Shannon-Wiener Index (H’), Evenness (e), and Species Similarity Index (IS). The compotition of arthropods were classes from herbivore, predator, parasitoid and detritivore. The sum of H’ is higher on paddy field with trap crop application than paddy field without trap crop application. Indicate that a stable relationship could be maintained between rice insect pests and their arthropod natural enemies. </p><p><strong>Keywords</strong> : Habitat modification, Trap crop, Arthropods, compotition, abundance, diversity</p>

We studied the abundance of arthropods in relation to forest patch size, edge orientation, distance from the forest - open-land edge, and stand characteristics in pine-dominated forests in northern Finland. Arthropod samples were collected using the sweep-net method. The total catch of arthropods, catches from the field layer and deciduous shrubs, the numbers of flying arthropods, small (<1 mm) arthropods, and the numbers of seven different arthropod taxa (viz. Linyphiidae (Arachnida), Cicadellidae (Homoptera), Diptera, Brachycera (Diptera), Nematocera (Diptera), and Hymenoptera and Ichneumonidae (Hymenoptera)) were lower in large forest patches (>5 ha) than in small patches (5 ha). The edge orientation and the type of adjacent open area (clearcut area or treeless mire) had no impact on the abundance of arthopods in the patches. The distance from the forest edge affected the total abundance of arthropods, small arthropods, flying arthropods, and Coleoptera (especially Cantharidae) in that all decreased in number from the forest edge to the interior of the forest stand. The abundance of many arthropod taxa correlated positively with the numbers of saplings, deciduous shrubs, and spruces. It was clear that the existence of these vegetation characteristics mainly explained the observed differences in the abundance of arthropods between forest patches of different sizes and also between forest edges and stand interiors.

AbstractArctic arthropods are essential prey for many vertebrates, including birds, but arthropod populations and phenology are susceptible to climate change. The objective of this research was to model the relationship between seasonal changes in arthropod abundance and weather variables using data from a collaborative pan-Canadian (Southampton, Herschel, Bylot, and Ellesmere Islands) study on terrestrial arthropods. Arthropods were captured with passive traps that provided a combined measure of abundance and activity (a proxy for arthropod availability to foraging birds). We found that 70% of the deviance in daily arthropod availability was explained by three temperature covariates: mean daily temperature, thaw degree-day, and thaw degree-day2. Models had an adjusted R2 of 0.29–0.95 with an average among sites and arthropod families of 0.67. This indicates a moderate to strong fit to the raw data. The models for arthropod families with synchronous emergence, such as Tipulidae (Diptera), had a better fit (average adjusted R2 of 0.80) than less synchronous taxa, such as Araneae (R2 = 0.60). Arthropod abundance was typically higher in wet than in mesic habitats. Our models will serve as tools for researchers who want to correlate insectivorous bird breeding data to arthropod availability in the Canadian Arctic.

High-yielding varieties are used as one of the technologies to increase rice productivity in Indonesia. Varieties, however, invite the arrival of arthropod during their growing phase. One of the method to manage arthropods during the growing stage is the use of high-yielding varieties. In this trial, IR-64, Ciherang, Situ Bagendit, Mekongga and Mixed Varieties were used. The mixed variety is a combination of IR-64, Ciherang, Situ Bagendit and Mekongga. These rice varieties are the most common varieties used by farmers in Bantul Regency. To collect arthropods, the traps used were sweep net, yellow sticky and pitfall traps. The purpose of this study was to determine arthropod’s diversity, evenness and dominance in different rice plant varieties in one planting season. The study was conducted in the village of Wijirejo, Pandak, Bantul, Yogyakarta. The observations were conducted in the evening between 16.00–18.00 p.m., with the interval of twice a week for 5 observations. Arthropods were identified up to the family level. This research resulted in the diversity index (Shannon-Winner) of 1.97–2.82 which is categorized as medium, the evenness index of 0.61–0.71, categorized as medium and the dominance index of 0.10–0.22, categorized as lower level. The ecosystemof the research area was unstable in diversity, evenness, and dominance due to the transition process, and it took quite some times to stabilize the rice fields. Therefore, a more thorough research is still necessary, especially for the ricegrowing season to follow.

This study aimed to determine the effect of refugia (Tagetes erecta and Zinnia elegans) plants on the relative abundance and diversity of Arthropod's dominance in the rice plant area and on rice yield. The Arthropods were observed by the visual control method at each rice growth stage. Observations were made during 15 minutes in five plots of rice area and one refugium block at three different times (08.00‒10.00, 12.00‒14.00, and 15.00‒17.00. The morphological features were identified and recorded to identify the species level and grouped according to their ecological niches. The relative abundance and Shannon Diversity Index were calculated. The rice plants' growth data and yield components were analyzed by ANOVA followed by DMRT if there were any significant differences among the treatments. Relative abundance of dominant arthropods on rice land planted with Zinnia elegans was Solenopsis geminata (11.07%), Leptocorisa oratorius (38.37%), and Hypolimnas bolina (0.17%) with species diversity index values of 3.25%; 2.94%, and 2.56%, respectively. In contrast, the relative abundance of arthropods in rice land planted with Tagetes erecta were Cardiochiles philippinensis (8.84%), Oxya chinensis (25.45%), and Scirpophaga incertulas (0.34%) with moderate diversity index values. The Tagetes erecta gave an equivalent result of rice yield with the control, namely 8,10 t/ha and 7,60 t/ha, respectively, while the Zinnia elegans offers rice yield of 6,30 t/ha.

Blood-feeding arthropods, particularly ticks and mosquitoes are considered the most important vectors of arthropod-borne diseases affecting humans and animals. While feeding on blood meals, arthropods are exposed to high levels of reactive oxygen species (ROS) since heme and other blood components can induce oxidative stress. Different ROS have important roles in interactions among the pathogens, vectors, and hosts. ROS influence various metabolic processes of the arthropods and some have detrimental effects. In this review, we investigate the various roles of ROS in these arthropods, including their innate immunity and the homeostasis of their microbiomes, that is, how ROS are utilized to maintain the balance between the natural microbiota and potential pathogens. We elucidate the mechanism of how ROS are utilized to fight off invading pathogens and how the arthropod-borne pathogens use the arthropods’ antioxidant mechanism to defend against these ROS attacks and their possible impact on their vector potentials or their ability to acquire and transmit pathogens. In addition, we describe the possible roles of ROS in chemical insecticide/acaricide activity and/or in the development of resistance. Overall, this underscores the importance of the antioxidant system as a potential target for the control of arthropod and arthropod-borne pathogens.

Arthropod diversity is generally influenced by the type of habitat in an agro-ecosystem. Crop diversity, soil types, nature of habitats (intensive, semi-intensive and natural), proximity to natural habitats, landscape complexity etc. are the major arthropod diversity influencing factors. Hence, this study was designed to investigate the diversity of various arthropod species among different habitats such as mango orchard, litchi orchard, vegetable field, organic field and uncultivated land during March 2021. Arthropod sampling was taken on every three- day interval using pitfall trap. The composition, relative abundance, and diversity indices of the arthropods of five different habitats were analyzed. Maximum abundance was recorded in uncultivated land (N = 398) and minimum in the vegetable field (N = 61). Shannon-Weiner Diversity Index (1.76) and species richness (9.67) were found highest in mango orchards. The greatest evenness was recorded in the vegetable field (0.91) and more dominance index was recorded in uncultivated land (0.60). There was a significant difference in total abundances of arthropods between vegetable fields than in the organic and uncultivated fields, being highest in uncultivated land followed by litchi, mango and organic field. Hymenopterans were the most abundant order (53.55%) followed by Coleoptera and Arachnida. These arthropods were crop pests and beneficial. Beneficial arthropods population was more than crop pests. Such beneficial arthropods play a vital role to deliver an ecosystem service. This study can help to develop a conservation and management protocol for beneficial arthropods in the agro-ecosystem.

The status of Myriapoda (whether mono-, para- or polyphyletic) and position of myriapods in the Arthropoda are controversial, an impediment to evaluating fossils that may be members of the myriapod stem-group. Parsimony analysis of 319 characters for extant arthropods provides a basis for defending myriapod monophyly and identifying those morphological characters that are necessary to assign a fossil taxon to the Myriapoda. The alliance of hexapods and crustaceans need not relegate myriapods to the arthropod stem-group; the Mandibulata hypothesis accommodates Myriapoda and Tetraconata as sister taxa. No known pre-Silurian fossils have characters that convincingly place them in the Myriapoda or the myriapod stem-group. Because the strongest apomorphies of Myriapoda are details of the mandible and tentorial endoskeleton, exceptional fossil preservation seems necessary to recognise a stem-group myriapod.

Abstract Arthropods play vital roles in various ecosystem functions and respond acutely to habitat manipulation. Diversity and community dynamics of arthropods are strongly correlated with ecosystem functioning. Arthropod community structure reflects habitat heterogeneity, as well as development and recovery of forest ecosystems after natural and anthropogenic disturbances. Arthropod community structure also reflects the degree of fragmentation and isolation of forest ecosystems on the landscape. Arthropods are good indicators of the overall biodiversity and ecosystem integrity of forests and can be used for evaluating and designing sound ecosystem management plans.

Shallots (Allium ascalonicum L.) from the Lilyceae family are annual horticultural plants. The aim of this research is to determine the effect of the application of organic fertilizer plus on the diversity of arthropods in shallot plants in peatlands. The method used in this research was a one-factor Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications. Data from arthropod identification results are grouped based on order and family which are presented in tabular form. Then an analysis was carried out using diversity indices, species richness and species evenness. The results of the research show that the most dominant arthropods are the predator group. The results also show that the level of arthropod species diversity is moderate, the level of arthropod species richness is low, the level of evenness of arthropod species shows an unstable distribution. The most dominant group of arthropods is the predator group and the results of the LSD analysis test at the 5% level showed a real influence on the diversity of arthropods in shallot plants in peatlands where organic fertilizer plus 125 g/hole was applied with an average of 48.40 individuals.

AbstractThe prairie grasslands have been transformed to become the primary source of agricultural production in Canada. Soon after its establishment, the Biological Survey of Canada recognised the urgent need to document the arthropods of the prairie grasslands, especially in the few pristine remnants. Although this initiative has yielded considerable progress in documenting the species present in the Prairies Ecozone, comprehensive ecological studies are sparse. Landscape effects on arthropods are well studied elsewhere, but no equivalent studies have been published for the Canadian Prairies. Crop rotation varies landscape composition annually, changes host plant resources in fields, and interacts with other agricultural inputs to disturb pest and beneficial arthropods. Despite only a handful of studies on grazing, there is an emerging pattern: moderate grazing increases arthropod diversity and benefits certain arthropod guilds. Abiotic inputs elicit variable responses from different arthropod taxa; Carabidae (Coleoptera) are best studied, with some information available for ants (Hymenoptera: Formicidae) and aquatic arthropods. Biotic inputs include arthropods released for biocontrol of weed and insect pests; evidence indicates that biocontrol agents of insects have a greater potential for impact on native communities of arthropods. The studies reviewed here reveal important trends and research gaps to be addressed in the future.
