Dynamics of trapped adult populations of Drosophila suzukii Matsumura (Diptera: Drosophilidae) and its parasitoids in Uşak Province, Turkey

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.

Late seasonal occurrence of the spotted wing pest in new invaded area

“…Now it appears to be a subcosmopolitan species, with distribution range between 50° S and 70° N (e.g. Hauser 2011, Lee et al 2011, Calabria et al 2012, Cini et al 2012, Kiss et al 2013, Březíková et al 2014, Deprá et al 2014, Kinjo et al 2014, Asplen et al 2015, Lengye et al 2015, Łabanowska & Piotrowski 2015, Lavrinienko et al 2017, Oboňa et al 2017, Japoshvili et al 2018, Ørsted & Ørsted 2019, Zengin & Karaca 2019.…”
