Abstract

Laboratory studies were conducted to evaluate the role of two aphid species (Aphis craccivora Koch and Myzus persicae Sultzer) and two temperature degrees on certain biological aspects of the green lacewing aphid Chrysoperla carnea (Neuroptera: Chrysopidae). In order to evaluate its potential as biological control agent, some biological parameters and its consumption capacity were studied on the two aphid preys under laboratory conditions. The biological parameters were the same when the predator fed on M. persicae and A. craccivora. There are no significant differences were observed in the biological parameters when C. Carnea was fed on the two tested aphid preys. The average aphid consumption of C. carnea larvae to complete its development was 537.23, 570.08 of A. craccivora while it was 507.73 and 519.42 of M. Persicae at 25 and 30 oC, respectively. Therefore, the larvae of C. carnea can be regarded as a biological control agent for controlling aphid species.
