Abstract
This study was conducted to determine the effect of rearing the Lady beetle Coccinella septempunctata L. on black bean aphid Aphis fabae Scolopi which was treated directly and indirectly with three concentration (2,4,8 %)of some proteins such as Universal amino Tech., Anabolic amino, Dronabol, Whey protein and Creatine , on some biological characteristics of the Ladybeetles. The results of this study showed insignificant effects of the used energiesers proteins on the mean of larval development period and mean of the pupal stage period, but they reduced the period of development insignificantly. While the adult coccinellids fed on black bean aphid treated directly with creatine of 8% conc. showed significant effects on the mean period of the pre–oviposition and oviposition period which was 5.80, 26.00 day respectively, as compared with 6.60, 24.00day respectively for control
