Spotted wing drosophila (SWD), Drosophila suzukii, is one of the most harmful pests causing serious damages to blueberries in Northern America and Europe. It is essential to seek alternatives to methyl bromide to ensure dis-infestation of this pest from agricultural products. We investigated the effect of X-ray irradiation (0, 50, 100, 200 and 300 Gy) on development and reproduction of SWD to meet this standard. When eggs were irradiated with the doses, some portion of the eggs hatched even at 300 Gy. The larvae hatched from the irradiated eggs did not pupate at 300 Gy, and they could not develop to adults even at 50 Gy. When larvae were irradiated, they developed up to pupa in some proportion. However above 100 Gy, there was no adult emergence. When pupae were irradiated, some of them emerged to adults. However, the adults could not produce eggs at all above 100 Gy. When adults were irradiated, oviposition occurred normally, but fecundity and hatchability were decreased as irradiation dose went up.
