Online published on 21 March, 2016. Abstract An experiment was conducted to find out the effects of different hosts on biology of green lacewing {Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) } and their feeding potential of prey under laboratory conditions at 26±2°C and 65±5% relative humidity (RH) during 2010–11. The results indicated that the incubation period of eggs of C. carnea females feeding on different hosts as larvae was different on different host from each other. The biology of C. carnea was completed in 26 days on Aphis craccivora, followed by Aphis gossypii (31 days) and Corcyra cephalonica (45 days). A single larva of C. carnea consumed A. gossypii and 97.33 eggs of Corcyra cephalonica, followed by A. gossypii (80.0±2.65 nymphs/adults) and A. craccivora (64.33±0.67 nymphs/adults) per day. However, all the three larval instars of C. carnea consumed 369.00±6.11 eggs of C. cephalonica, followed by A. gossypii (277.67±4.37 nymphs/adults) and A. craccivora (206.67±1.86 nymphs/adults) during the whole larval period.
