| Abstract | ||
| The experiments were carried out in the laboratories of the mass rearing units of biological enemies Plant Protection Directorate / Ministry of Agriculture /Abu Ghraib in order to study the effect of different nutritional mixtures of media on some biological charecters of the adult predator Chrysoperla carnea(stephens). The results showed that the highest egg laying was obtained at the mixture (0.5 g yeast + 1.5 g Spirulina + 4g Honey + 0.5 Ml Water), reached to 881.33 eggs / female. In addition, the feeding on the mixture (0.5 g Spirulina + 4g Honey + 0.5 Ml Water) showed a positive effect in the incubation period of eggs, with an average of 3.54 days. The feeding on the mixture (0.5 g Ganoderma + 4g Honey + 0.5 Ml Water) resulted in better egg hatching ratio, reaching to 93.33%. A positive effect was shown with females’ survival when fed on the mixture (0.5 g yeast + 1.5 g Spirulina + 4g Honey + 0.5 Ml Water), the average longevity was 54 days. The longest male longevity was 36 days recorded at the mixed media of (0.5 g yeast + 1.5 g Spirulina + 4g Honey + 0.5 Ml Water). Longest post oviposition period was 5 days recorded at the mixed media of (1.5 g Spirulina + 4g Honey + 0.5 Ml Water). The longest period of eggs laying was at the mixture (Spiro Lina 1.5 g + yeast 0.5 g + honey 4 g + sterile distilled water 0.5 ml) was (46.47) days. Result indicated that some of the mixed media have a positive effect on the performance of aphid lion therefore; these combinations can be used in the quantitative mass rearing of the predator aphid lion. | ||
