Drosophila suzukii (Matsumura) is an invasive pest of soft-skin fruits. Due to its recent introduction, there are currently no studies about its chemical control in Argentina. The aim ofthis research was to evaluate five formulated insecticides with different mode of actionagainst eggs, larvae and adults of D. suzukii under laboratory conditions. The product formulated with spinosad was the most effective insecticide, since it showed high efficacy againstall life stages. Furthermore, females exposed to spinosad and lambda-cyhalothrin laid fewereggs. Further studies need to be conducted in order to corroborate these results underfield conditions.
