Interpretive Summary: Spotted wing drosophila, Drosophila suzukii Matsumura, a native of Southeast Asia, is a pest of small and stone fruits. Introduced into California in 2008, the pest has rapidly established populations across the Pacific Coastal States. Its ability to attack healthy, ripening fruit (as opposed to overripe and rotting fruit favored by other so-called “vinegar flies”) makes it a potential economic threat to a host of soft- and thin-skinned fruit crops including cherry, raspberry, blackberry, blueberry, strawberry, peach, plums, pluots, nectarines, juice grape, table grape, and wine grape. Coordinated research projects to determine host preference, seasonal phenology, biology, and management options are taking place among entomologists in Washington, Oregon, and California. A description of the pest and initial findings on its biology, life history, known and expected geographic range, management and monitoring techniques, and economic considerations are presented and discussed.
