Interpretive Summary:

Technical Abstract: The spotted wing Drosophila (SWD), Drosophila suzukii, was reported in the Pacific Northwest (Oregon, Washington, British Columbia) in 2009. The fly is able to oviposit directly into intact ripe and ripening fruit, so it is of great economic concern to the small fruit industries in region. Fruit infested with this insect is unmarketable and unacceptable to consumers. The Pacific Northwest is one of the top producing regions for caneberries, blueberries, and strawberries. The short generation time and infestation inside the fruit make control challenging. Because of its recent introduction into our region, it is of critical importance that we identify currently registered pesticides that are efficacious against this pest infesting strawberries as well as disseminate information to growers and crop consultants on monitoring and management protocols (chemical, cultural and biological) that are efficacious and least harmful to beneficial insects and pollinators. Data on the effective control of SWD are extremely limited, so it is imperative that the current management recommendations that are established are disseminated to growers of susceptible crops in the region. In addition, information of our current understanding of the basic biology and overwintering phenology of SWD must be made available to growers so that more robust Integrated Pest Management programs can be developed in the future.
