An experiment was carried out to study the effect of insecticides viz. diafenthiuron 50 WP, clothianidin 50 WDG, Acetamiprid 20 SP, Imidacloprid 17.8 SL, Thiamethoxam 25 WG, Flubendiamide 20 WG, Indoxacarb 15.8 EC, Spiromesifen 22.9 SC on the egg hatchability and fecundity rate of Chrysoperla carnea in the bio-control laboratory, College of Agriculture, Nagpur during 2016-17. Clothianidin was found most harmful to with 13.00, 30.29, 58.18 per cent egg hatchability during 48, 72 and 96 hrs respectively, and with a fecundity rate of 212.67 eggs/female. Whereas, diafenthiuron was found most safe with 28.33, 47.50, 78.37 per cent eggs hatchablity during 48, 72, 96 hrs respectively and with fecundity rate of 355.33 eggs/female.
