Seletividade de inseticidas ao complexo de inimigos naturais na cultura do algodão (Gossypium hirsutum L.). Pesquisa Agropecuária Tropical, Goiânia, v. 35, n. 2, p. 123-127, maio/ago. 2005. Disponível em: <https://www.revistas.ufg.br/pat/article/view/2260>.1517-6398http://repositorio.bc.ufg.br/handle/ri/13150The selectivity of insecticides was evaluated in the complex of natural enemies of the cotton (Gossypium hirsutum L.) crop. The cultivar Deltapine was used in a randomized block experimental design, with seven treatments and four replications. The treatments, all in their commercial formulation, were: control; thiamethoxam (300 g.ha-1); lufenuron (300 mL.ha-1); betacyflutrin (800 mL.ha-1); imidacloprid (70g.ha-1); diflubenzuron (6,0 g.ha-1); and endosulfan (1500 mL.ha-1). The insecticides were sprayed at 45 days after germination. Besides the initial evaluation, other evaluations were performed three and seven days after insecticide application. Each plot was sampled by the fabric beating method, with two random beatings per plot. Natural enemies were identified and counted. Three days after application, the insecticides thiamethoxam (300 g.ha-1), lufenuron (300 mL.ha-1), and diflubenzuron (60 g.ha-1) did not showed negative effect on the complex of predators present in the cotton. However, seven days after application, only the lufenuron treatment maintained the selective effect over predator complex.porAcesso AbertoInseticidaControle biológicoGossypiumInsecticideBiological controlArtigo
