The selectivity of insecticides for the complex of predators of the pests of cotton plant was evaluated in field experiment, in Goiânia- Goias (Brazil), during the crop 1998/99. The experimental design was the randomized blocks with seven treatments and four repetitions (check, clorfluazuron, Bacillus thuringiensis, alanycarb, endosulfan and acephate in two amounts). The samplings were accomplished in beforeapplication, two days, seven and fourteen days after the treatment.
