ABSTRACT
Survival of predaceous arthropods were observed after 1 and 2 applications of insecticides on cotton during 1996 and 1997 growing seasons in Blackville, SC. Insecticide classes included representatives from the following: biological, insect growth regulator (IGR), naturalyte, pyrrole, carbamate, pyrethroid, chloronictinyl, and organophosphate. The biological, IGR, and naturalyte classes had low toxicity to predators. Carbamate and pyrrole classes were moderately toxic to the predaceous arthropods. The pyrethroid, chloronictinyl, and organophosphate classes were the most toxic causing dramatic reductions in predator numbers.
