Resumo: The 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. KEY-WORDS: Insecticide; biological control; Gossypium.

Avaliou-se a seletividade de inseticidas sobre o complexo de inimigos naturais na cultura do algodão (Gossypium hirsutum L.), no município de Goiânia, GO. Utilizou-se a cultivar Deltapine e o delineamento experimental em blocos ao acaso, com sete tratamentos e quatro repetições. Os tratamentos foram: testemunha, thiamethoxam (300 g.ha-1), lufenuron (300 mL.ha-1), betacyflutrin (800 mL.ha-1), imidacloprid (70 g.ha-1), diflubenzuron (6,0 g.ha-1), endosulfan (1500 mL.ha-1), em suas apresentações comerciais. A pulverização dos inseticidas foi efetuada aos 45 dias após a emergência das plantas. Além da avaliação prévia, foram efetuadas avaliações aos três e sete dias após a aplicação dos inseticidas. As amostragens foram realizadas através do método de batida de pano, com duas batidas ao acaso por parcela, identificando-se e contando-se, o número de inimigos naturais presentes. Três dias após a aplicação dos tratamentos, os inseticidas thiamethoxam (300 g.ha-1), lufenuron (300 mL.ha-1) e diflubenzuron (60 g.ha-1), considerando os produtos comerciais, não apresentaram efeito de choque sobre o complexo de inimigos naturais presentes na cultura do algodoeiro. Entretanto, aos sete dias após a aplicação, apenas o tratamento com lufenuron manteve a seletividade.a esses artrópodes predadores.
