FEEDING RESPONSE OF Chrysoperla carnea (Steph.) LARVAE TO PISTACHIO PSYLLA NYMPHS

This study was carried out under laboratory conditions at 25±2°C and 65±5% R. H.. The Chrysoperla carnea (Steph.)larvae in that experiments was fed on pistachio psylla nymphs (Agonoscena pistaciae Licht.) and compared with Mediterranean moth eggs (Ephestia kuehniella Zeller; Lepidoptera: Pyralidae) as standard host. The results showed with significant difference, a mean predatism of predator larvae of two hosts were tested was 561.44±37.82 and 433.78±26.51 respectively. The greatest predation efficiency of C. carnea larvae was on pistachio psylla nymphs then on E. kuehniella eggs.
