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 (Th) was reduced the highest attack coefficient was 2.558 cages for 2ed larvae stage and the lowest attack rate was 1.509 cages for 3rd larva stage. However, the highest handling time was 23.274 minutes for 2ed larva stage and the lowest handling time was 10.651 minutes for 1st larva stage.
