Sub-lethal effects of Cyhalothrin and Fluvalinate on biology of Spodoptera litura F

Sub-lethal effects of cyhalothrin and fluvalinate on the biology of Spodoptera litura F. were studied under laboratory conditions. Five concentrations of each insecticide were tested on cauliflower leaves against fourth instar larvae of S. litura. The results revealed that larval and pupal stages we...

Summary:Sub-lethal effects of cyhalothrin and fluvalinate on the biology of Spodoptera litura F. were studied under laboratory conditions. Five concentrations of each insecticide were tested on cauliflower leaves against fourth instar larvae of S. litura. The results revealed that larval and pupal stages were prolonged in comparison to control. Males were more sensitive to insecticides than females and fluvalinate was more toxic to males than cyhalothrin. The copulation time, fecundity and fertility of eggs on insects exposed to insecticides were also less compared to control insects.
