| Abstract: |
| Common green lacewing, Chrysoperla carnea (Stephens) is an important predator that occurs naturally in many agricultural and horticultural cropping systems and feeding on a large variety of pests including aphids, whiteflies and scale insects. In commercial insectaries, larval stage of this predator was usually reared on eggs of a factitious host, Mediterranean flour moth, Anagasta kuehniella (Zeller), because of its low rearing cost. The main objective of this study was to determine the preimaginal development and survival as well as adult longevity and fecundity of this predator feeding on eggs of A. kuehniella (ad libitum feeding) as larvae food and honey solution 20% as adults food under laboratory condition (25±1˚C, 60±5% RH, and a 16hL:8hD photoperiod). Feeding on A. kuehniella eggs resulted in high survival rate and short developmental time of preimaginal stages. So that, 95.64±2.52 percent of first instar larvae developed to pupa and 88.89±4.8 percent of pupae emerged to adult lacewing. Means of larval and pupal developmental times were estimated 7.67±0.1 and 9.0±0.13 days respectively. Longevity of females (35.2±1.52 days) was significantly higher than male adults (25.8±2.08 days). A female lacewing laid an average of 62.64±2.53 eggs during her life time and females pre-oviposition, oviposition, and post-oviposition periods were obtained 4.2±0.07, 13.3±0.37 and 17.8±1.67 days respectively. In conclusion, high survival rates and short developmental times of preimaginal stages of C. carnea after feeding on eggs of A. kuehniella shows that this factitious host has high nutritional quality to lacewing and could be used for mass-rearing of this lacewing in insectaries. |
