Spotted wing drosophila (SWD), Drosophila suzukii, is considered the most important pest of soft fruit in Washington State. Current control methods require weekly insecticide applications, which are unsustainable. So far however, no effective biological controls have been identified. Large numbers of yellow dung flies were observed in a Whatcom County red raspberry field following an early spring manure application. This prompted an investigation into the potential of yellow dung flies to impact SWD populations by feeding on overwintering females returning to berry fields early spring.
