Abstract: Results of laboratory experiments revealed that the total development period (egg to adult emergence) of the common green lacewing Chrysoperla carnea lasted for 19.15, 19.35, 19.95, 20.15, 20.60 and 22.50 days when the larvae were fed with Bemisia tabaci, eggs of Corcyra cephalonica, Heliothis armigera, Aphis gossypii, Amrasca biguttula and neonates of Heliothis armigera respectively. Larval development was rapid on eggs of C. cephalonica (8.20 days) and prolonged on neonates of H. armigera (11.10 days). Pupal development period was quicker on B. tabaci and A. biguttula (7.40 days) and prolonged on neonates of H. armigera (8.40 days).
During development each larva of C. carnea consumed an average of 732.35 eggs of C. cephalonica, 662.53 eggs of H. armigera, 419,18 A. gossypii, 409.55 neonates of H. armigera 329.70 pupae of B. tabaci and 288.45 nymphs of A. biguttula. In all the cases, the third instar larvae consumed the major portion of the total number consumed (60-80%). The most suitable preys, resulting in rapid development, for C. carnea were pupae of B. tabaci and eggs of C. cephalonica.
