SUMMARY
Spotted wing drosophila, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) is a polyphagous, invasive pest of many fruit crops. Although its native to East Asia, the pest has rapidly spread its range in many parts of the Americas and Europe since the first record in 2008. Drosophila suzukii was first recorded on strawberry crops in Erzurum, Eastern Turkey in 2014. This study was conducted in order to establish the presence of D. suzukii on cherry in Karaman. For this purpose, six apple cider vinegar traps were placed in three cherry orchards during period April 30th to June 25th 2017 and D. suzukii was confirmed in all surveyed locations. Totally, 39 D. suzukii adults (24$ and 15$) were captured in the traps during the monitoring period on cherry orchards. This paper presents a new record of the occurrence of D. suzukii in Karaman (Ermenek), Central Anatolia on cherry. Also this is the first report of the presence of D. suzukii in cherry grown in Turkey.

INTRODUCTION
Drosophila suzukii (Matsumura), also known as Spotted Wing Drosophila in the United States, and Cherry Drosophila in Japan, is an invasive, highly polyphagous and a devastating pest that originates from East Asia (Kanzava, 1935; Walsh et al., 2011). It was first described by Matsumura in Japan in 1931. The first record outside of Asia was in Hawaii in 1980 (Hauser, 2011), then in California in 2008 D. suzukii was found for the first time (Hauser, 2009). In Europe, it was first reported in Spain and Italy in 2008 (Grassi et al., 2011; Raspi et al., 2011; Calabria et al., 2010; Cini et al., 2012). Since then, the geographical distribution of D. suzukii has spread rapidly and many other European countries made their first record (Figure 1).
Adults of D. suzukii are small flies approximately 2.25-4.0 mm long (females are usually slightly larger than males), with red eyes, yellowish brown thorax and dark brown abdomen with black transverse stripes. Males display a black spot on the outer edge of each wing and two sex combs on the first and second segments of their front legs, females possess a large serrated ovipositor, clear wings without spots and lack sex...
