Spotted wing drosophila, Drosophila suzukii, causes damage on several fruits include strawberry in Korea. D. suzukii lays egg inside fruit surface, and this behavior makes D. suzukii hard to detect, so many countries designated D. suzukii as a quarantine pest. Recently, Australian government demand methyl bromide fumigation on Korean export strawberry to prevent D. suzukii invasion. In this study, we tested methyl bromide to control D. suzukii, and also tested separate and concurrent treatments of methyl bromide to evaluate phytotoxicity on strawberry. When 40 g/m3 of methyl bromide was treated for 3 hours, all stages of D. suzukii were completely controlled. When treated separate and concurrent with cold temperature treatments of methyl bromide, there’s no specific phytotoxicity on strawberry. This result indicates that separate and concurrent treatments of methyl bromide do not cause phytotoxic effect on strawberry and methyl bromide is effective to control D. suzukii.
