The spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is one of the important invasive pests of cultivated berry and stone fruits worldwide. The purpose of this study was to determine the population growth of D. suzukii in vineyards in Canakkale Province from 2014 to 2017. The numbers of D. suzukii male and female individuals caught in the bait traps were recorded weekly. Drosophila suzukii population started to emerge from late September to February in all years. The maximum population of D. suzukii in the 2014-2015 sampling period was recorded on 29 November and 13 December 2014 at 153 individuals. In the 2015-2016 and 2016-2017 sampling periods, the maximum populations were 103 and 141 individuals recorded on 12 and 4 December, respectively. The results indicated that the D. suzukii population increased in the Canakkale Province in three sampling years during November and December. These results are important as they provide information useful for the control of D. suzukii in vineyards in this province.
