Abstract

Chrysoperla carnea is a general predator of worldwide insect pests like whiteflies, thrips, mealy bugs, aphids, mites as well as eggs of different arthropods. Studies on the biology of C. carnea are important because they attack a wide range of hosts which generally difficult to control. The incubation period of C. carnea ranged from 2-4 days with 2.73±0.24 days was recorded on sugarcane whitefly. The 1st Instar larval period was 2.97±0.23 with 2-4 day ranges, followed by 2nd Instar and 3rd Instar period with 3.80±0.38 ranging from 3-7 days and 3.37±0.16 with 3-4 (days) ranges. However, C. carnea complete their larval period with in 10.13±0.45 days, ranged from 8-14 and pupal period takes 8.17±0.29 days with 6-9 (days) ranges. The average larval survival rate was 83.33±12.22%, adult survival rate 80.00±12.87%, male longevity 22.27±0.96 days and female longevity 26.43±0.89 days were recorded. The pre oviposition, oviposition and Post oviposition days was recorded 2.60±0.22, 17.43±0.64 and 6.00±0.3. The results further revealed that the C. carnea female lay eggs 12.53±0.46/ day with 83.31±1.87 % fertility.
