1. 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

2. Bioactivity of essential oils from Artemisia against Diaphania hyalinata and its selectivity to beneficial insects
ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absi

3. INSECTICIDAL ACTIVITY OF DIENAMIDES ON CABBAGE CATERPILLAR AND BENEFICIAL INSECTS
The demand for new insecticides is increasing due to the appearance of insect populations that are resistant to currently used products. New insecticides should be efficient in controlling pests and present low toxicity to non-target organisms. Ascia monuste (Lepidoptera: Pieridae) is a destructive pest of cole vegetables, and the fire ant Solenopsis saeviss

4. The predator Coenosia Attenuata Stein (Diptera, Muscidae) on cultivated plants from Brazil
ABSTRACT Coenosia attenuata Stein (1903) is a predatory fly that is commonly found in greenhouses and open fields preying on whiteflies, leafminers, psocopterans and other insects. The species is widespread in the Old World and its distribution has expanded in recent times to Neotropical countries including Chile, Colombia, Costa Rica, Ecuador and Peru. We r

5. Insects associated with tropical foliage produced in the coffee growing region of Colombia
We conducted a survey of insects and pest management practices on 34 farms growing ornamental tropical foliage plants in the central coffee region of Colombia over two years. Tropical foliage provided habitat for a diverse range of insects. In total, phytophagous or detritivorous insects from six orders, 40 families and 62 genera were collected. The most com

6. Influência da agregação larval na história de vida de Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae) / Influence of larval aggregation on life-history traits of Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae)
In insects, the gregarious habit has been shown to improve foraging and defense against predation to both larval and adult stages. Egg clusters could also be beneficial through increased larval hatching. In this study, we tested the hypothesis that egg clusters and larval aggregations of the neotropical butterfly Ascia monuste orseis (Godart, 1819) (Pieridae

7. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

8. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

9. Mass rearing beneficial insects and the renaissance of biological control.
E possivel criar hospedeiros para producao in vivo de inimigos naturais de maneira eficiente a confiavel. Isto pode ser economicamente rentavel, mesmo se os artropodos forem criados em plantas, como na producao de acaros predadores. A producao massal de hospedeiros tem sido amplamente empregada na criacao de predadores e parasitoides, tanto para liberacao in

10. Criação de Anastrepha fraterculus (Wied.)(Diptera: Tephritidae) em dieta artificial e avaliação de produtos fitossanitários utilizados no sistema orgânico de produção sobre esta espécie e insetos benéficos / Rearing Anastrepha fraterculus (Wied.)(Diptera: Tephritidae) in artificial diet and evaluation of phytosanitary products used in the organic system of production on this specie and beneficial insects
A mosca-das-frutas sul-americana, Anastrepha fraterculus (Wied.) é um dos principais problemas à produção de frutíferas no Brasil. No sistema orgânico de produção, há diversas alternativas para o controle das moscas-das-frutas, como óleos, extratos de plantas e caldas. Entretanto, para a maioria dessas substâncias, não há a comprovação cientí

11. Insects associated with the composting process of solid urban waste separated at the source
Sarcosaprophagous macroinvertebrates (earthworms, termites and a number of Diptera larvae) enhance changes in the physical and chemical properties of organic matter during degradation and stabilization processes in composting, causing a decrease in the molecular weights of compounds. This activity makes these organisms excellent recyclers of organic matter.

12. Interações ecológicas em Malpighiaceae no cerrado: compartilhamento de guildas de herbívoros e variações nos resultados da interação formiga-planta / Ecological interactions in Malpighiaceae in the Cerrado: sharing of guilds from herbivores and variations in the results of ant-plant interaction
Ecological interactions represent essential tools for a better understanding of natural communities, having in animal-plant relationships important models for study. For that, become needful phenological analyses of plants, capable of demonstrating the flowering strategies and with it the ways of temporal organization of resources available for herbivores. T
