Özet:

This study aimed to determine the egg parasitoids Trissolcus Ashmead, 1893 (Hymenoptera: Scelionidae) species of Sunn pest (Eurygaster spp. Hemiptera: Scutelleridae), in cereal areas of Ağrı, Iğdır and Van provinces in the years 2015-2016. Sunn pest egg packages were collected in the grain cultivation areas where the pest is common. Collected eggs were placed in a plastic tube and cultured at 25±1°C and 65±5% humidity. As a result of the study, Sunn pest as egg parasitoid Trissolcus grandis (Thomson, 1860), T. vassilievi (Mayr, 1879), Telenomus chloropus (Thomson, 1861) (Scelionidae) and Ooencyrtus sp. (Encyrtidae) species were determined. T. grandis parasitoid species were identified from the egg samples taken from Ağrı, while Trissolcus grandis, T. vassilievi, Ooencyrtus sp. and Telenomus chloropus were identified from the samples taken from Iğdır, and T. grandis and T. vassilievi were identified from the samples taken from Van. The distribution rates of the detected species within the population were Trissolcus grandis 56%, Telenomus chloropus 22%, Trissolcus vassilievi 10%, and Ooencyrtus sp. 12%. It was determined that the most common species in the provinces where the study was conducted was T. grandis.
