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: 3rd 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±50C, 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.
