The identifying of sunn pest Eurygaster laporte, 1832 (Hemiptera: Scutelleridae) species, the state of loss and the natural enemies in the grain cultivation areas in Igdir and nearby provinces

Eurygater Laporte, 1832 (Hemiptera, Scutelleridae) species, state of loss and natural enemies were described in this study which was carried out in cereal fields in Iğdır and nearby provinces between the years 2015 and 2016. In this study Eurygaster integriceps (Puton, 1881) and E. maura (Linnaeus, 1758) have been determined. It was determined that, among the aforementioned species, E. integriceps was the dominant species found in Ağrı, Bitlis, Hakkari and Van while E. maura was the dominant one in Ardahan, Erzurum, Iğdır and Kars. The average sunn pest density in wheat fields of Iğdır was determined as (0,3-19,6) and 2,97 (0,3-23,33) nimf and YNSE/m2 in 2015 and 2016, respectively. The absorption ratio per grain was determined as 1,31 (0,1-7,7)% and 1,07 (0,2-5,3)% on the average. It was determined that, Trissolcus grandis (Thomson, 1861), notably being the most common one, T. vassilievi (Mayr, 1879), Telenomus chloropus (Thomson, 1861) (Hymenoptera: Scelionidae), Ooencyrtus sp. (Hymenoptera: Encyrtidae) specieswere all determined as a sunn pest egg parasitoids. Elomya lateralis (Meigen, 1824), Ectophasia oblanga (Robineau-Desvoidy, 1830) and Phasia subcoleoptrata (Linnaeus 1767) (Diptera: Tachinidae) species were determined as adult parasitoids.
