Mating Competitiveness of Sterile male Drosophila suzukii Under Different Atmosphere Condition

The implementation of the sterile insect technique (SIT) to control Drosophila suzukii requires the released sterile males to compete with their wild counterparts. We performed multiple-choice mating tests to assess the effect of irradiation and atmosphere treatments on the mating competitiveness of sterile males under laboratory conditions. Overall, irradiation and atmosphere treatments did not influence the sterile males’ ability to compete with the untreated counterparts.
