abstract
The study was carried out on different hosts at IPM laboratory Tandojam during 2018-2019. The duration of various life stages i.e., eggs, larvae and pupae on aphid, eggs of Angoumois grain moth and mealy bug were observed. The fecundity female, longevity of female were recorded on various hosts. The predatory behaviour of larvae of Chrysoperla Carnea was recorded daily by offering them a known number of aphids, eggs of Angoumois grain moth and mealy bug. The increase in the weight of larvae of C. carnea after consumption of food was daily recorded in 3^rd instar. The mean larval emergence from the eggs was observed as 16.4±1.60, 16.4±1.50 and 16.2±1.28 on Angoumois grain moth, cotton aphid and mealy bug respectively. The pupal period was 112.6±14 on Angoumois grain moth, cotton aphid and mealy bug respectively. The fecundity of female on three hosts comes out to be 1490.4±40.78, 1594.6±53.28, 1402.6±42.81 on Angoumois grain moth, cotton aphid and mealy bug respectively. The weight recorded in 3^rd instar on three different hosts were aphid 0.0720±0.004, mealybug 0.018±0.003 Sitotroga Cereallela 0.0625±0.002 on Angoumois grain moth, cotton aphid and mealy bug respectively.
