Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), spotted wing drosophila (SWD), has been found in California, Florida, Oregon and Washington. This fly is native to Southeast Asia and has been established in Hawaii since 1986. Hosts of SWD include, but are not limited to: blueberries, blackberries, strawberries, raspberries, cherries, grapes, apple, peach, plum, persimmon and uncultivated Rubus spp. Symptoms of infested fruit are small scars and indented soft spots on the surface, which are made by the female’s ovipositor as she lays eggs in the fruit. Larvae feed inside the fruit, resulting in fruit collapse and secondary fungal and bacterial infections. Drosophila suzukii is a temperate species, and it may be able to survive in much of the continental United States.
Under IPPC standards, Drosophila suzukii is considered to be a pest that is present, only in some areas in the United States.
