Abstract
Green lacewing predator(Chrysoperla carnea) is polyphagous predator. It is currently mass-reared and used in biological control of insect pests. The experiment was carried out under laboratory conditions at 25±2°C and 65±5% RH at Hama Biological Control Center, during 2017, to find out a better and high efficiency nutritional diet for mass-rearing of adult of C. carnea. Four adult diets were tested under the laboratory conditions. Fertility, larval period, pupal period and adult longevity were studied. The results showed that the 1st diet that contained of water, honey, yeast and pollen in a ratio of (9:3:1:1) respectively was better than all other diets, that contain a ratio of (1:1:1/ 6:2:1/ 9:3:1) of water, honey and yeast respectively. When the adults fed on 1st diet the fertility of females was 409.33 eggs, larval period was 9.92 days, pupal period was 7.92 days and longevity of female and male were 51.5, 38.5 days.
Key words: Nutritional diets, Adult, Chrysoperla carnea.
