Conteúdo: | Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a widely distributed pest species of soft- skinned fruits. Recent studies suggest the use of sterile insect tech- nique (SIT) as a control method for this species; however, many factors can im- pact effectiveness of a SIT programme, including the environmental conditions. Environmental condition is critical at the time of the release and in the days after- wards, since it may impact sterile insects? survival and ability to mate. Thus, we veri- fied the influence of temperature and relative humidity on mating and survival of fertile and sterile D. suzukii, when insects were food provided or deprived. Highest mating rates occurred when sterile or fertile flies provided with food were exposed to 25ºC or 81%? 100% relative humidity, while temperatures of 10 and 35ºC and hu- midity below 60% impaired mating. Overall, mating rate among food- deprived flies was low in all temperatures and humidity levels tested, but fertile insects were more prone to mate when compared to sterile flies. Survival was negatively influenced by high temperatures, low relative humidity and food deprivation. The information pre- sent in this study is useful to be considered for release of sterile D. suzukii.
