The study of distribution and field efficacy of egg parasitoids was conducted in several wheat fields in north east of Syria (Amoda, Al-Qamishly, Al- Qehtanya, Al-Jwadya and Al-Malikya) in the 2011 field season. The results of surveys and taxonomy showed that fives parasitoid species belonging to Scelionidae family and order of Hymenoptera are: Trissolcus grandis Thomson, Trissolcus simoni Mayr, Trissolcus semistriatus Ness, Trissolcus vassiilievi Mayr and Gryon fasciatus Priener. The abundant species were T. grand which occurred in all sites and rate parasitism reached to 37.74% to all eggs, and T. vassilievi which occurred in all sites except Amoda and parasitism reached to 32.10%. T. semistriatus recovered in Al-Qamishly, Al- Qehtanya and Al-Malikya and parasitism reached to 16.98%. T. simoni was recovered only from Amoda, Gryon faciatus only from Al-Malikya. Overall parasitism rates reached 44.17% throughout the season.
