Abstract: | An artificial rearing method was designed for the generalist predator, Chrysopa pallens (Rambur). The rearing media were formulated based on, Orius strigicollis diets for feeding larvae, and two diets for adults were prepared with insect source and non‐insect as their main components. Development of the predators was successfully obtained with the diets for both larval and adult stages. The impact of these diets was recorded for growth during the larval stage and oviposition rates by the females. Total development period and mortality rate of, C. pallens were about 26.9 days and 11%, respectively. The females showed better reproduction with average of 2019 eggs over their life span of 89 days when the artificial diet with non‐insect source was provided. On overall basis the life expectancy and fecundity was better when compared with previous findings. |
