Abstract: 

The toxic effect of insecticides tested against Coccinella septempunctata Linn. revealed that l cyhalothrin (0.008%), profenophos (0.05%) and dimethoate (0.03%) were proved as highly toxic. The insecticides, viz., acephate (0.037%), thiamethoxam (0.025%), imidacloprid (0.005%), diflubenzuron (0.05%) and novaluron (0.02%) were found moderately toxic, while NSKE (5.0%) and M. anisopilae (2 × 107 spores l–1) were proved least toxic.
