Abstract The spotted wing drosophila fly, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is a pest which caused serious crop losses to soft-skinned fruits such as cherries, strawberries, and grapes. In this study, population dynamics of D. suzukii and its associated parasitoids were investigated. The surveys were conducted at one location of Uşak province, Turkey, between April and December of 2017 and 2018. For this purpose, the baited traps were weekly hung on the fruit trees. Population of D. suzukii in 2017 and 2018 peaked at the end of October and in mid-November, respectively. Moreover, three parasitoid species, namely, Leptopilina heterotoma (Thomson, 1862), Ganaspis xanthopoda (Ashmead, 1896) (Hymenoptera: Figitidae), and Pachycrepoideus vindemiae (Rondani, 1875) (Hymenoptera: Pteromalidae), were identified associated with the pest. Among these, G. xanthopoda and L. heterotoma are new records for Turkey Eucoilinae fauna. P. vindemiae was the most abundant parasitoid in both years, while G. xanthopoda was detected only in 2017. This study is the first research to detect parasitoids of D. suzukii in Turkey. |
