ABSTRACT
Laboratory studies were carried out to determine the influence of varying amounts of different proteins in the diet of adult Chrysoperla carnea (Stephens). Results show that proteins play a vital role in the fecundity, fertility and all the biological parameters of F1 for mass rearing. The tested proteins were: Casein, Protein hydrolysate, Torula yeast and Nu lure. Al these proteins were tested in laboratory at four concentrations, i.e., 1, 3, 5 and 7 mg/ml in diet. Significantly higher fecundity 785.12±25.7, fertility 89.23±0.36 % of eggs and longer oviposition period 42.13±1.11 days were recorded in adults feeding on a diet containing Nu lure followed by protein hydrolysate (control diet). The F1 progeny larvae that developed from adults consuming (Nu lure 5ml) diet had the shortest larval and pupal periods and complete all developmental stages in shortest period of time. Insects reared on different concentrations of proteins. Insects rear on different diets compared on the basis of egg to adult survival, female (%) and pupal weight (g) with low and high protein concentrations.
