13. Bioaccumulation of metals in aquatic insects of streams located in areas with sugar cane cultivation
Streams located in areas of sugar cane cultivation receive elevated concentrations of metal ions from soils of adjacent areas. The accumulation of metals in the sediments results in environmental problems and leads to bioaccumulation of metal ions by the aquatic organisms. In the present study, bioaccumulation of the metals ions Al, Cd, Cr, Cu, Fe, Mg, Mn an

15. 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

18. AvaliaÃÃo da toxicidade de inseticidas utilizados em algodoeiro para cycloneda sanguinea (Linnaeus, 1763) (Coleoptera: Coccinellidae). / Toxicity evaluation of insecticides used in cotton crop to Cycloneda sanguinea (Linnaeus, 1763) (Coleoptera: Coccinellidae).
To assess the effects of three insecticides used in cotton crop on third-Ãnstar larvae and adults of the ladybeetle Cycloneda sanguinea (Linnaeus), four trials were conducted under greenhouse conditions. For the accomplishment of the tests, the cultivar BRS IPÃ, with twenty five days, were used and the insecticides were sprayed with a manual sprayer. After

19. Physiologic selectivity of insecticides used in coffee crop on the predators Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) and Cryptolaemus montrouzieri Mulsant, 1853 (Coleoptera: Coccinellidae) / SELETIVIDADE FISIOLÃGICA DE INSETICIDAS UTILIZADOS EM CAFEEIRO SOBRE OS PREDADORES Chrysoperla externa (HAGEN, 1861) (NEUROPTERA: CHRYSOPIDAE) E Cryptolaemus montrouzieri MULSANT, 1853 (COLEOPTERA: COCCINELLIDAE).
For the use of predators for pest control in the coffee crops in association with pesticides it is important that these compounds be selective to these natural enemies The physiologic selectivity of pesticides used in coffee crop on these predators Chrysoperla externa (Hagen 1861) (Neuroptera Chrysopidae) and Cryptolaemus montrouzieri Mulsant 1853 (Coleopter

20. Modifications of reproductor system of Brontocoris tabidus (Heteroptera: Pentatomidae) after exposition to deltamethrin / Modificações do aparelho reprodutor de Brontocoris tabidus (Heteroptera: Pentatomidae) após exposição à deltametrina
Beneficial insects such as Pentatomidae predators can be negatively or positively affected by insecticides. This research studied the impact of the deltamethrin Decis 25CE, with the concentrations of 0,0165%, 0.033% e 0.066%, representing the treatments T1, T2 and T3, respectively, on the reproductive system of males and females of the predator Brontocoris t

21. Action of some insecticides with sterilizing properties on Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) and its predator Doru luteipes (Scudder, 1876) (Dermaptera: Forficulidae) / Ação de alguns inseticidas com propriedades esterilizantes sobre Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) e seu predador Doru luteipes (Scudder, 1876) (Dermaptera: Forticulidae)
The fall armyworm, Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae), is an important pest of the maize culture. In the tropical area, it causes severe damages, reducing the income from grains by up to 60%. Its control is normally carried out by the application of conventional insecticides, but this method is not recommended due to the negative as

22. Aspectos biológicos e tabela de vida de Podisus nigrispinus (Heteroptera: Pentatomidae) com a presa Anticarsia gemmatalis (Lepidoptera: Noctuidae) em soja resistente / Biological aspects and life table Podisus nigrispinus (Heteroptera: Pentatomidae) with the prey Anticarsia gemmatalis (Lepidoptera: Noctuidae) in a resistant soybean cultivar to insects
The biological control and the resistance of plants are important tactics of integrated pest management in the soy culture. This research aimed to evaluate the possible impacts of the resistant IAC-24 soy cultivar on the nymph stage, on reproduction and longevity and on the parameters of the life and fertility tables of the predator Podisus nigrispinus (Dall
