1. Silicon as resistance inducer in to control black aphid Aphis craccivora Koch, 1854 in Phaseolus lunatus lima beans
RESUMO São poucos os registros no Brasil de insetos associados à cultura da fava; entre eles, destaca-se o pulgão preto Aphis craccivora Koch, 1854. O objetivo deste estudo foi avaliar os efeitos da aplicação de silício na indução de resistência de plantas de feijão-fava Phaseolus lunatus a esse inseto. O experimento foi conduzido no Laboratório d

2. Physiological potential and initial development of soybean plants as a function of seed treatment
RESUMO O tratamento de sementes é um processo que auxilia no controle de insetos e patógenos iniciais, além de possibilitar à cultura atingir seu potencial máximo de produção e promover proteção à plântula. Objetivou-se avaliar o desempenho fisiológico de sementes e o desenvolvimento inicial de plantas de soja, em função do tratamento de sement

3. A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil
Resumo: Avaliações biológicas que usam a abordagem de condição de referência se baseiam na comparação entre a biota observada em locais teste e a presente em locais íntegros ou minimamente impactados. Entretanto, em muitas regiões do mundo, estes locais são escassos ou inexistentes. Neste estudo, a abordagem alternativa proposta por Chessman e Roy

4. Quantitative impacts of different planting arrangements on the populations of natural enemies in soybean
ABSTRACT. Natural biological control is an important alternative for the control of insect pests using natural enemies that occur naturally in agroecosystems. The potential of these insects can increase when they are adequately managed. Thus, the objective of this study was to quantify the populations of natural enemies in soybean cultivars with different gr

5. Spatial Variability of Soil Fauna Under Different Land Use and Managements
ABSTRACT Geostatistics allows the evaluation of the distribution pattern of data with high spatial variability in agricultural systems. This study aimed to evaluate the spatial variability of biological diversity indices of soil fauna under different land (agriculture and forest). Samples were collected in seven areas (millet, soybean, corn, eucalyptus, past

6. A broad pH range and processive chitinase from a metagenome library
Chitinases are hydrolases that degrade chitin, a polymer of N-acetylglucosamine linked β(1-4) present in the exoskeleton of crustaceans, insects, nematodes and fungal cell walls. A metagenome fosmid library from a wastewater-contaminated soil was functionally screened for chitinase activity leading to the isolation and identification of a chitinase gene nam

7. CLINICAL ASPECTS OF THE POISONING BY THE PESTICIDE ENDOSULFAN
Endosulfan is an organochlorine insecticide, widely used in insect control. Unfortunately, it is also an acute neurotoxic compound to both insects and mammals, including humans, and has been responsible for many severe poisonings and several fatal cases. Endosulfan also imitates or enhances the effect of the female hormone estrogen, having the capability of

8. Spatial distribution of triatomines in domiciles of an urban area of the Brazilian Southeast Region
Reports of triatomine infestation in urban areas have increased. We analysed the spatial distribution of infestation by triatomines in the urban area of Diamantina, in the state of Minas Gerais, Brazil. Triatomines were obtained by community-based entomological surveillance. Spatial patterns of infestation were analysed by Ripley’s K function and Kernel de

9. Beauveria Bassiana Applied to Broiler Chicken Houses as Biocontrol of Alphitobius Diaperinus Panzer (Coleoptera: Tenebrionidae), an Avian Pathogens Vector
ABSTRACT Beauveria bassiana is naturally found in broiler chicken houses, and has been shown to be active against the lesser mealworm, Alphitobius diaperinus. The effectiveness of soil application of B. bassiana in emulsifiable oil-type formulation (Unioeste 4 isolate) to control the lesser mealworm in commercial poultry house was evaluated. The fungus was a

10. Energy substrate used by workers of leaf-cutting ants during nest excavation
Energy substrate used by workers of leaf-cutting ants during nest excavation. In this study we aimed to ascertain whether leaf-cutting ant workers lose body reserves (fat or sugars) as a function of nest excavation. For each treatment, we isolated 10 workers of Atta sexdens into two experimental groups, Control (C- without excavation) and Soil (S- with excav

11. Sampling and spatial distribution of Sphenophorus Levis in sugar cane for site specific control / Plano de amostragem e distribuição espacial visando o controle localizado de Sphenophorus Levis na cultura da cana-de-açúcar
No Brasil o bicudo da cana-de-açúcar, (Sphenophorus levis Vaurie) tem se tornado uma praga importante da cultura, podendo causar perdas expressivas na produtividade. Percebe-se que são raros os estudos sobre a distribuição espacial desta praga no campo, e tais estudos são imprescindíveis para o desenvolvimento de planos de amostragem, visando à aplic

12. Composição e variabilidade enantiomérica de α-pineno em Constrictotermes cyphergaster (Silvestri, 1901) (Isoptera; Termitidae) / Composition and enantiomeric variability of α-pinene in Constrictotermes Cyphergaster (Silvestri, 1901) (Isoptera; Termitidae)
Termites are eusocial insects of isoptera order that part in seven families. In this study we analyze the chirality of α-pinene in the defensive secretion that C. cyphergaster (Isoptera, Termitidae, Nasutitermitinae) this compound showed that among the majority of termite volatile. Along with checking the chirality was made a study seeking to correlate
