Abstract: Breeding of Drosophila (Sophophora) suzukii on blueberries was studied during the entire ripening season from July to October in Hokkaido, northern Japan. The species began to use blueberries from late July in the years 2016, 2017, and 2018 and from early August in 2019; about 95% of the fruits were infected by D. suzukii females from late August to late September. The active breeding of D. suzukii on blueberries peaked in late August, and number of adults that emerged from a single blueberry fruit was 4.2±2.1 (n=20), with the maximum number being 9. For breeding of D. suzukii on cherry fruits, the damage ratio was quite low, because of its fruiting period being about 1 month earlier than the appearance of D. suzukii in Hokkaido.
