The green oak roller, Tortrix viridana is one of the most important pests of oak in Kurdistan province, west of Iran. According to this fact that chemical control of pests in natural ecosystems is very difficult or impossible, finding the safe ways to control of these pests are necessary. One of the most important methods, is using of natural enemies. The first step in this way is identification of these agents. Tortrix viridana has many parasitoids. In this investigation, we tried to identification of parasitoid flies (Dip.: Tachinidae) and determination effect of them on reduction of pest population. This project was conducted in Marivan and Bane regions during 2012 and 2013. By weekly visiting infested forests, 100 larvae and pupae were collected and transported to the laboratory and placed in containers and by regular visits of cages, parasitoids were collected and parasitism rate and kind of parasitoid in each stage and finally the percentage of parasitism were determined. Three tachinid species were identified: Nemorilla maculosa (Meigen, 1824), Eumea mitis (Meigen, 1824) and Pales pavida (Meigen, 1824).This is the first report of E. mitis from Iran. The results showed that these parasitoids attacked the old larval stages but abundance and parasitism rate of these flies were very low.
