Abstract | The present study was designed to study the lethal effects of new chemistry, conventional and IGRs insecticides using a diet incorporation bioassay against second and third instar S. litura. Initially all the insecticides were used in recommended field doses for their lethal effects and later on all the IGRs and new chemistry insecticides were evaluated for their lethal effects keeping in view their environmental safety. The results showed among insecticides Emamectin Benzoate, a bacterial metabolite, proved highly effective and caused 100 percent mortality of the insects followed by Chlorpyriphos, a conventional organophosphate (OP) insecticide. Among IGRs Lufenuron was the most effective insecticide by causing 100 percent mortality in the insects exposed. These findings will help us to devise bio-rational IPM strategies against S. litura in agro-ecosystem.
