Chrysoperla carnea (steph.) is a major, cosmopolitan predator of some whitefly and Aphid. This research was evaluated relative consumption of three diets and effects of prey kinds on developmental times, mortality percentage of larvae and pupae, consumption rate, longevity, fecundity, fertility, and sex ratio on C.carnea. All larvae stages and adults were reared on the different diets: 3 rd nymphal stages Shizaphis graminum, and Bemisia tabaci (Biotype B), or a semi artificial diet (consist of honey, yeast, essential amino acid, and Distilled water) (10%, 15%, 25%, 2.5%, and 47.5%). All experiments were conducted at 25±5 0 C, 60±5% RH, and photoperiod of 16:8 (L:D). Larval stages consumed 192.1±2.57 (no.) nymph Shizaphis graminum, and 479.7±4.08 nymph Bemisia tabaci in which results show significant difference between hosts consumed by larvae .There were significant differences between rate of oviposition, larvae longevity 12.29±0.81, 14.02±0.9 and 10.07±0.3 day ,fertility ,and sex ratio on different diets (female: male when larvae fed on age of nymph Shizaphis graminum ,Bemisia tabaci and artificial diet was 53:47, 52:48 and 57:43). Considering above parameters, artificial diet can be a best choice for mass rearing C. carnea.
