The role of three different hosts viz., eggs of Corcyra cephalonica, brinjal aphids and mango mealy bugs on development, longevity, larval and pupal period of green lacewing (Chrysoperla carnea), was investigated in laboratory conditions (50 ± 1°C, 70 ± 5 % RH and photoperiod of L16: D8). In this study Chrysoperla was fed on Corcyra eggs, brinjal aphids and mango mealy bugs. Significant effects of host on larval duration, total developmental period, pupal duration, per cent larval survival and adult longevity of green lacewing were observed. The average larval period of C. carnea fed on was 14.40, 15.20 and 15.60, respectively. Pupal duration of 9.45, 10.02 and 9.77, respectively was recorded in same order of prey. Also the adult longevity of adults from eggs Corcyra, brinjal aphid and mango mealy bugs treatment was 25.40, 26.20 and 27.80 days for males and 31.40, 32.40 and 36.80 days for females. All the results showed that Total developmental period and per cent larval development suggested that eggs of C. cephalonica as better food for C. carnea.
