ABSTRACT

The generalist predator, green lacewing, Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) has a key role in integrated pest management (IPM) strategies for many crop pests. The influence of different prey types has been studied to strengthen the C. carnea. Current in-vitro study was made to figure out the effects of different prey on mortality and certain biological characteristics of C. carnea. The highest mortality rate (66.43±2.13%) was for larvae, which fed upon Oleander aphid, Aphis nerii. Less larval mortality (7.86±2.37%), larval period (164.57±8.16 h), maximum pupal weight (9.86±0.41 mg) and emergence (95.13±2.03%) was observed when C. carnea was provided with eggs of Sitotroga cerealella. Bervicornye brassicae was performed well than A. nerii but was found least successful as compared to eggs of S. cerealella. Both aphid species were significantly good in performance when fed to C. carnea larvae with S. cerealella eggs than their solo effect. Results depicted that mortality factor and life parameters of C. carnea larvae are influenced by its prey type which they fed on. These results of the study could be used to improve the rearing and conservation strategies to increase C. carnea population and their predatory activities.
