Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department of Agricultural Biochemistry Summary: The Pink bollworm, Pectinophora gossypiella is the most destructive pest of cotton crop in Egypt. Chemical insecticides play a major role in controlling the Pink bollworm but they caused environmental pollution, this pollution can be reduced by using the safer biopesticides. This study aims to contribute to the toxicological, biological and biochemical effects of three biopesticides (Dipel-2x, Abamectin and Spinosad) and one recommended pyrethroid insecticide (Esfenvalerate) on Pink bollworm insect, the four tested pesticides had high toxic effect on neonate and 3rd larval instar, neonate larvae were more susceptible to the effect of four tested insecticides than third instar larvae, the toxic effects of four pesticides were correlated with time of treatment. The high insecticidal effect was presented in long treatment interval (48 hrs.). The results revealed the following findings:- Male moths were more susceptible to the effect of tested pesticides than females. Abamectin was more effective pesticide against neonate, 3rd instar larvae and adults followed by Spinosad, Esfenvalerate and Dipel-2x. The four pesticides produced high deleterious effects on the development of Pink bollworm treated on neonate larvae
