| Você sabe que as abelhas são insetos? Os insetos são os seres mais adaptados do planeta e considerados a forma de vida dominante na Terra! Isso porque existem mais de setecentas mil espécies de insetos. São tantos e com formas de corpo tão diferentes que às vezes é difícil reconhecê-los. Mas todos eles têm algumas características em comum. Você quer saber o que abelha, borboleta, gafanhoto, pulga, formiga e mosca têm em comum? Todos têm um par de antena, três pares de pernas e um esqueleto externo, chamado de exoesqueleto. Existem outras semelhanças e várias diferenças. Alguns insetos, como o mosquito da dengue, causam doenças e são nocivos. Mas a maioria tem um importante papel na vida humana e de outros animais. Entre os insetos importantes, as abelhas... |

| We studied stomachs contents of 50 specimens of four common cuckoo species (Cuculidae) from southern Brazil: Guira guira (Gmelin, 1788) (n = 21), Coccyzus melacoryphus (Vieillot, 1817) (n = 8), Crotophaga ani (Linnaeus, 1758) (n = 11), and Piaya cayana (Linnaeus, 1766) (n = 10). We measured stomach volume and prey were identified and quantified based in their dimensions. The size of the prey was associated with bill width and body mass. Diet items were analyzed and identified to the lowest possible taxonomic level, based on literature, scientific collection data, and specialists. The diet of the four species was composed by 100% animal species, with invertebrate dominance. Only in G. guira stomachs the presence of vertebrates was observed more than once... |

| Insecticide resistance survey is an in-situ biomonitoring method to assess potential impact of pesticides that exhibit direct economic consequences when leading to control failure of insect pest species. Nonetheless, the latter phenomenon is frequently neglected. Their spatial dependence and mapping are also seldom considered and when complexes of related pest species are involved, such as the rice stink bugs from the Neotropics, Oebalus poecilus, and O. ypsilongriseus, the scenario is even worst. Insecticide use is common against both species, particularly with the neonicotinoid thiamethoxam, and despite suspicion of a shift in O. poecilus historical dominance and complaints of control failure, the role of this insecticide in this context was never... |

| The domestic pig (Sus scrofa) was used as a model to study arthropod succession on carcasses under tree shade and out of shade in southern Nigeria. Carcass decomposition took longer periods under tree shade than in exposed sites, at 24.5 and 16.5 days, respectively. Four decomposition stages - fresh, bloated, decay, and dry - were observed. No significant variabilities were recorded in the types and patterns of infestation of the carcasses by arthropods in both locations. Four classes of arthropods - Insecta, Arachnida, Diplopoda and Crustacea - were recorded. The class Insecta dominated the total arthropods collected with 24 families, and formed 94% of the catches. The other three classes each had one family represented, and contributed only 2% of the... |

| AbstractHyaluronidases are enzymes that mainly degrade hyaluronan, the major glycosaminoglycan of the interstitial matrix. They are involved in several pathological and physiological activities including fertilization, wound healing, embryogenesis, angiogenesis, diffusion of toxins and drugs, metastasis, pneumonia, sepsis, bacteremia, meningitis, inflammation and allergy, among others. Hyaluronidases are widely distributed in nature and the enzymes from mammalian spermatozoa, lysosomes and animal venoms belong to the subclass EC 3.2.1.35. To date, only five three-dimensional structures for arthropod venom hyaluronidases (Apis mellifera and Vespula vulgaris) were determined. Additionally, there are four molecular models for hyaluronidases fromMesobuthus... |

| The screening of Bacillus thuringiensis (Bt) Cry proteins with high potential to control insect pests has been the goal of numerous research groups. In this study, we evaluated six monogenic Bt strains (Bt dendrolimus HD-37, Bt kurstaki HD-1, Bt kurstaki HD-73, Bt thuringiensis 4412, Bt kurstaki NRD-12 and Bt entomocidus 60.5, which codify the cry1Aa, cry1Ab, cry1Ac, cry1Ba, cry1C, cry2A genes respectively) as potential insecticides for the most important insect pests of irrigated rice: Spodoptera frugiperda, Diatraea saccharalis, Oryzophagus oryzae, Oebalus poecilus and Tibraca limbativentris. We also analyzed their compatibility with chemical insecticides (thiamethoxam, labdacyhalothrin, malathion and fipronil), which are extensively used in rice crops.... |

| ABSTRACT Although the majority of threatened species are likely to be tropical insects, knowledge of the diversity, ecological role and impact of insect biodiversity loss on ecosystem processes is very limited. Specimens belonging to four families of Heteroptera: Pentatomidae, Coreidae, Alydidae and Rhopalidae, were collected from a protected area in the Paraná Forest, the largest ecoregion of the Atlantic Forest, in Argentina. The assemblages were characterized and the biodiversity estimated, and they were compared with the assemblages found in five other protected areas in the Brazilian Atlantic Forest. In our study area, Pentatomidae had the greatest richness and diversity; Coreidae was the second most diverse family, with highest sampling deficit,... |
