In this study, the effects of cold storage on the parasitization rate, longevity, emergence rate and sex ratio of cold stored adults of Trichogramma evanescens (Westwood, 1833) (Hymenoptera: Trichogrammatidae) and their F1 progeny were investigated. The parasitoid adults were stored for 1, 2, 3 and 4 weeks at 10ºC. Although parasitism rate of the cold stored adults declined depending on the increasing storage periods, parasitization per F1 female did not change. The longevity of parental adults and of its F1 progeny decreased depending on the length of the storage period, but the decrease in the parental generation was more prominent than that of the F1 progeny. The percent parasitoid emergence from the host eggs parasitized by cold stored adults was 96.55 % at the control but decreased to 85.09 % after 4 weeks storage. Female biased sex ratios were observed for all storage periods in the parental and F1 generation
