Abstract
Coccinella septempunctata is the generalist, representative predator that is potentially used as biological control agent in many crop pest management programs. A comprehensive and critical review of published and formerly unpublished studies was accomplished to evaluate the effects of insecticides such as imidacloprid, hexaflumuron, dimethoate, deltamethrin, pyriproxyfen, spinosad, lambda-cyhalothrin, bifenthrin, acetamiprid, fenazaquin, quinalphos and neemix on C. septempunctata. Data generated clearly indicates severe effects of used insecticides on its neurophysiological and behavioral responses indicating loss of co-ordination, paralysis as well as reduce fecundity, longevity and growth. Further studies are required to focus mainly on the measure to evaluate their real effects under field conditions
