Effect of Host, Corcyra cephalonica (Stainton) on the Development of Chrysoperla carnea (Stephens)

An experiment conducted in the laboratory on the effect of host, Corcyra cephalonica on the development of Chrysoperla carnea (Stephens) revealed that the maximum eggs (53.29 per day) were consumed in the treatment of 125 eggs/day which also recorded minimum larval and pupal periods of 8.04 and 9.17 days, respectively. Whereas, the treatment 100 eggs/day noted maximum pupal weight (8.42 mg) and the highest fecundity (350.75 eggs/female) as well as the maximum adult longevity (46.50 days). The food offered as 25 eggs/day has shown the adverse effect on the development of predator.
