Spotted-wing drosophila, Drosophila suzukii (Matsumura), is regulated in Mexico because of economic damage it causes to crops. Demands for export products in national and international markets are increasing, and compliance with mitigation measures in the field is required to minimize use of insecticide. It is necessary to develop environmentally friendly alternatives, such as the sterile insect technique, that also might be part of an integrated pest management (IPM) program. Effects of irradiation with Cobalt-60 on quality parameters (emergence rate, longevity, and flight ability) and fertility of D. suzukii adults were evaluated. Adults emerged from 5-day-old irradiated pupae reared on artificial diet. Doses of radiation evaluated were 60, 70, 80, 90, 180, and 200 Gy. No significant statistical differences between irradiated and non-irradiated flies were observed in quality parameters, emergence rate of 53.667–74% (F_8,12 = 1.55, P = 0.2433), longevity of 51.53–40.22 hours (F_8,12 = 0.24, P = 0.9544), and flight percentage 36–54.30% (F_6,14 = 2.05, P = 0.1258). One hundred percent of sterility induction was determined at 180 and 200 Gy, and fertility of D. suzukii females pre-confined with irradiated males and post-confined with fertile males gradually recovered. Data suggested the use of the sterile insect technique is promising as a component of an IPM program to control D. suzukii.
