Abstract

Biological characteristics of Chrysoperla carnea (Stephen.) fed on Hyalopterus pruni (Goff), Brevicoryne brassicae (L.) and Aphis pomi (Degeer) were studied under laboratory conditions. Developmental time of C.carnea on the above mentioned aphids were 24.75, 25.77 and 30.75 days, respectively. Preimeainal mortality was 60.69, 43.75 and 63.1%, respectively. Female longevity of C.carnea was equal to 28, 27.5 and 19.7 days, and total eggs laid was 402, 428 and 375 eggs, respectively. It can be concluded that B. brassicae was the most suitable prey for development and reproduction of C.carnea in laboratory conditions.
