1. Persistence of insecticides used in peach orchards to larvae and adults of the predator Chrysoperla externa (Neuroptera: Chrysopidae)
RESUMO Este trabalho teve como objetivo avaliar a persistência (duração da atividade nociva) de cinco inseticidas utilizados no controle de pragas em pessegueiro, em larvas e adultos do predador Chrysoperla externa. Os inseticidas foram pulverizados em plantas de videira cv. Bordô utilizando-se a máxima dosagem recomendada para o pessegueiro. Semanalmen

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. The invasive white ginger lily ( Hedichium coronarium ) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir
ABSTRACT The invasive white ginger lily (Hedichium coronarium - J. Köenig, 1783) simplifies the trait composition of an insect assemblage in the littoral zone of a Savanna reservoir. Invasive plants are believed to shift the trait composition of aquatic insects dwelling in banks of lentic ecosystems. In this study, we analyzed the relationship between the p

6. Predation on microcrustaceans in evidence: the role of chaoborid larvae and fish in two shallow and small Neotropical reservoirs
This study was focused on the predation upon microcrustaceans by an invertebrate predator (chaoborid larvae), and vertebrate predators (fish), in two small reservoirs in southeastern Brazil, with and without macrophytes, in two climatic periods (dry and rainy seasons). Chaoborus larvae were sampled in the limnetic zone, as they are scarce in the littoral, an

7. Aspectos bioecológicos de dermápteros (Insecta, Dermaptera) presentes em canaviais da região de Piracicaba / Bioecological aspects of Dermaptera naturally occurring in sugar cane fields located in Piracicaba, state of São Paulo, Brazil
A partir de 2017 ficará proibida a queima nos canaviais, tornando obrigatória a colheita sem queima prévia. Esta nova tendência de colheita irá resultar em mudanças nas relações tróficas presentes no canavial. A broca da cana (Diatraea saccharalis) é considerada uma pragachave da cultura e é responsável por uma perda significante de produtividade

8. O extrato de neem (Azadirachta indica) causa alterações no desenvolvimento ninfal, no aparelho reprodutor e sistema digestivo do predador Supputius cincticeps (Heteroptera: Pentatomidae)? / Does the neem (Azadirachta indica) extract cause nymphal development, the reproductive system and digestive tract of the predator Supputius cincticeps (Heteroptera: Pentatomidae)?
The subfamily Asopinae presents important species of predators, as Supputius cincticeps (Stal) (Hemiptera: Pentatomidae). These stinkbug present potential for the biological control of Lepidoptera defoliators in eucalyptus plantations in Brazil.Botanical insecticides, mainly neem (Azadirachta indica), are alternative for the control of herbivore insects of a

10. Reproductive characteristics of the predator Podisus nigrispinus fed with an insect resistant soybean variety.
The objective of this research was to evaluate the effect of the insect resistant soybean genotype IAC 17 on reproductive characteristics of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) females compared to the soybean insect susceptible genotype UFV 16. Treatments were: T1) females of P. nigrispinus fed on plants of the UFV 16 and Anticarsia gemm

11. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

12. Diversidade de Coccinellidae (Coleoptera) em plantas aromáticas (Apiaceae) como sítios de sobrevivência e reprodução em sistema agroecológico
Studies show that Apiaceae may provide concentrated vital resources for predator insects, stimulating their abundance, diversity and persistence in agricultural systems, thereby increasing their efficiency as biological control agents. Among the predatory insects, Coccinellidae (Coleoptera) on many different species both as larvae and adults, complementing t
