| Abstract | ||
| Laboratory experiments were carried out in Economic Entomology Department, Faculty of Agriculture, MansouraUniversity under two constant temperature of 25 ±2 Co and 30 ± 2 Co and relative humidity of 70 ± 5%, to evaluate the effect of six prey types on some biological aspects of Chrysoperla carnea (Steph.) The obtained results indicated that the shortest developmental time was obtained when larvae of C. carnea reared on Aphis craccivora Koch, while the longest time was recorded on Icerya seychellarum Westwood eggs. The total consumption rate from the six prey insects by the larval stage of C. carnea showed significant difference. Concerning to the food preference for the predator larval among prey insects tested, the average male and female longevity of C. carnea was significant longer when fed on I. seychellarum eggs, followed by A. craccivora, Aphis gossypii Glover, Earias insulana (Boisd.) eggs, Myzus persicae (Sulzer), and shorter on Aonidiella aurantii Maskell nymphs. Meanwhile the prey type had a significant effect on female fecundity. The highest number of eggs obtained when females of C. carnea fed on A. craccivora followed by A. gossypii, A. aurantii nymphs, M. persica, I. seychellarum eggs, while the lowest numbers were achieved on E. insulana eggs | ||
