dc.description.abstractDrosophila suzukii, an invasive insect pest, has had major impact on blueberry production since its detection in the continental United States in 2008. Current management programs rely primarily on frequent applications of broad-spectrum insecticides, therefore it is important for growers to have specific information on the efficacy and residual activity of these insecticides. We evaluated efficacy of various insecticides registered for use against D. suzukii in season-long treatment programs in southern highbush and rabbiteye blueberries in Georgia. In semi-field bioassays, all treatment programs typically produced higher mortality than controls within one day after treatment. Insecticides also showed reduced numbers of offspring produced following exposure to treated plant material. Within the treatment programs, organophosphates and pyrethroids were the most effective. During 2014 field season residue analysis levels were also below maximum residue limits for exportation to Canada and Japan. This study shows that effective, season-long programs can be designed for growers.
