Abstract
Effect of prey kind on some biological aspects of C. Carnea was studied under laboratory conditions of 28 ±2 oC and 65±5 %R.H. The studied preys were Thrips tabaci Lindr, Gynaikothrips ficorum Marshall, Aphis durantae Thobald, Spdoptera littoralis (Biosd.), andcontrol fed on (A. craccivora Koch.).
The obtained results revealed that there were significant differences between the total developmental periods (26.9, 20.6, 23.0, 19.8 days when this predator reared on T.tabaci, G. ficorum, A. durantae, and S. littoralis compared with (15.4 ± 0.4) days with (15-16) in control (A. craccivora). There were highly significant differences between oviposition periods (17.9, 15, 7.6, and 10.0 days compared with 10.0 days in control (A. craccivora), respectively. Adult longevity (female: 30.5, 15.6, 25, 25.1 days but recorded 20.0 days in control (A. craccivora). and male: 30, 20.5, 27.2, and 20.9 days) compared with 15.4 days in case of rearing on A. craccivora. While fecundity (number of eggs/female: 109, 131, 156, and 43 eggs) compared with 210eggs in control, (A. craccivora Koch.). And sex ratio (female: male); 1:2, 1:2, 1:1 and 1: 2 respectively. All results are recorded for the preys: T.tabaci, G. ficorum, A. durantae, and S. littoralis, respectively. While, the control. Fed on A. craccivora was (1:1).
