Abstract

Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae ) (Chestnut Gal Bee) is accepted one of the most important harmfulls of Chestnut  forests in the world. It prevents the development of bud on chestnut trees and hence the yield of fruit is limited 50-70% percent. To make biological struggle with Chestnut Gal Bee, one laboratory was established within Yalova Management Directorate. Bootanomyia almusiensis (Torymidae), Eupelmus urozonus (Eupelmidae), Mesopolobus tibialis (Pteromalidae), Mesopolobus dubius (Pteromalidae), Torymus flavipes (Torymidae), Torymus sinensis (Torymidae),  Torymus sp (Torymidae), Mesopolobus spp (Pteromalidae), Pediobius sp (Eulophidae), Megastigmus spp (Torymidae) were determined within gals that were brought from Gacik Village to Artvin in 2014. The adults of 2.600 Torymus sinensis and 7.000 Chestnut Gals were brought from Italy in 2015 and they were released to nature in Gacik Village. On 04.09.2015, The larvaes of T.sinensis were found in 6 (% 3,8) numbers of 157 gals taken in the area that the species of T.sinensis were released, moreover the larvaes of T.sinensis were found in 2 (% 1,5) numbers of 132 gals taken in the area that the species of T.sinensis weren’t released. It was determined that the adults of T. sinensis were successfully located in the area.
