Studies on biological parameters of Chrysoperla carnea (Stephens) on Schizaphis graminum (Rondani) aphid were carried out in Insecatry-Bio control Laboratories, Insect Pest Management Programme, Department of Plant and Environmental Protection, National Agricultural Research Centre, Islamabad, Pakistan. The results indicate that incubation period was 3.8±0.08 days with 87.0% hatchability. The developmental duration of first, second and third instar larvae were 3.2 ± 0.13, 4.0±0.21 and 4.8±0.25 days, respectively. The total larval developmental duration was 12.0 ±0.67 days with 85.05% survival rate of larvae. The larval predatory potential was 414.6±0.05 aphid per larvae. The total duration and survival rate from egg to adult emergence was 24.6± 0.06 days with 73% survival rate. The pre oviposition, oviposition and post oviposition periods were 9.2±1.25, 34.6±1.72 and 7.4±1.02 days, respectively. The female and male longevity was 51.2 ± 2.18 and 32.4±2.04 days respectively. The female fecundity was 384.2±21.20 eggs per female with 11.16±1.31 eggs per day per female. [ABSTRACT FROM AUTHOR] |
