Abstract
The present experiments was carried out in both experimental farm and laboratory of Plant Protection Research Institute, Sakha, Kafr El-Sheikh governorate for study the impact of Myzus persicae(Sulzer) which educated on different host plants on biological attributes of Chrysoperla carnea (Stephens)influence of the green peach aphid, M. persicae as a prey. There was no significant different in the incubation periods for C.carnea when the predator fed on M. persicae preys reared on different host plants (faba bean, kidney bean and cowpea).The shortest developmental time of the three larval instars for C.carnea recorded on M. persicae which reared on faba bean were 3.3, 4.6 and 4.9 days, respectively. Meanwhile, the longest developmental time of the three larval instars for C.carnea recorded on M. persicae which reared on Cowpea were 4.0, 5.4 and 5.7days, respectively. The total developmental time of immature stages was 23.1, 25.4and 26.3 days on the three tested host plants with significant differences. Male Longevity was 26.09, 21. 63 and 20.18 days with significant differences among C.carnea which fed on M. persicae was reared on the three leguminous plants. Fecundity of females was 109.20, 97.42 and 94.42 eggs/ female with significant differences among C.carnea which fed on M .persicae was reared on the three leguminous plants.
