The present study was aimed to find out the effect of different diets on some biological parameters of the adult predator, Chrysoperla carnea and to introduce an economic artificial diet for its mass-rearing. The C. carnea was reared for four successive generations in laboratory conditions on baker's yeast, honey, and sucrose (YHS) (2: 1: 1). The effect of seven different diets including VAYH, AK + HY, WMHY, WMH, YS + SC, YVYH, and YMH was studied on some biological parameters of the fifth generation. All experiments were done under 25 ± 10C, 65±5% RH and 16:8 h (L:D) conditions. Data were analyzed using a completely randomized design (CRD) with 15 replicates. Results revealed that the YVYH diet influenced the biological traits of the predator more positively. The mean of female longevity, male longevity, oviposition period, post oviposition period and fecundity calculated 43.53, 34.86, 26.26, 10.46 days and 618.07 (eggs), respectively.
