The citrus leafminer (CLM), Phyllocnistis citrella Stainton, is one of the most serious pests of Iran's citrus nurserystocks. In this study, the effects of gamma radiation at doses of 100–450 Gy on the biological and reproductiveparameters of P. citrella were determined. The results showed that the mean percentage of pupal mortalityincreases with a rise in the dose. Also, the mean values of this parameter were higher for irradiated females,indicating higher sensitivity. The mean fertility of the irradiated females mated with normal males was affecteddrastically and reached zero at 300 Gy. The hatchability of the eggs laid by normal females mated with irradiatedmales dropped to 2% at the highest irradiation dose of 450 Gy. The results of this test showed that females have ahigher radio-sensitivity than males. The competitiveness values fluctuated from 0.2 to 0.6 at doses higher than200 Gy. The results showed that the male CLMs irradiated with sterilizing doses could compete suitably with theuntreated males in laboratory conditions.
