Abstract

This study was conducted at College of Sciences/Al- Mustansiyriah University,aimed to examine the functional response of local predator Chrysoperla carnea (Stefens ((Neuroptera:chrysopidae) The predator is one of the important natural enemies of (Gelechiidae) family eggs. Result showed that the Carves of functional response of the predator green lacewing Chrysoperla carnea (stephens) (Neuroptera:chrysopidae) larvae to various densities of tomato moth Tuta absoluta (Lepidoptera:Gelechiidae) eggs showed that the larvae of predator belongs to second type (Cyrtoid) of functional response. The rate of attack coefficient (a) was increased while the handling time (T_h) was reduced the highest attack coefficient was 2.558 cages for 2^ed larvae stage and the lowest attack rate was 1.509 cages for 3^rd larva stage. However, the highest handling time was 23.274 minutes for 2^ed larva stage and the lowest handling time was 10.651 minutes for 1^st larva stage.
