Abstract
In an attempt for integrated control of carob moth Ectomyelois ceratoniae in pomegranate orchards of varamin, mass release of Trichogramma embrphagum egg parasitoid was employed during 1995-1996 in a 5000 m2 orchard. A check plot with the same size (5000 m2) apart from treated orchard was also included for comparison. In each release 100 Tricho-card containing parasitized laboratory reared Ephestia kuehniella eggs were used. Each Tricho-card contained 2000 parasitized eggs. A total of ten mass releases, every 10 days were executed from late May until mid July. Number of adult catches, parasitized eggs and damaged fruits were evaluated statistically. In this investigation, by release of inundative rate of T. embiyopha gum in pomegranate orchards in Varamin, number of adult catches reduced from 20.1 in chcek plot to 10.5 in treated plot. The rate of parasitized eggs increaseld from 17.5% under natural conditions to 53.1 in mass released plot. The rate of damaged fruits at harvest, reduced from 72.20 in check plot to 24.2 in treated plot.
