spotted wing drosophila

Spotted-wing drosophila (SWD; Drosophila suzukii; Family: Drosophilidae) is a key pest that targets a wide variety of susceptible fruits including tree stone fruits (e.g., cherries) and berries (e.g., strawberries, blueberries, raspberries and blackberries). Spotted wing drosophila is a temperate fruit fly, native to Southeast Asia; preferring temperatures of 20-30 o C. It is known to infest thin-skinned fruit. Adult male spotted wing drosophila have a single dark spot near the tip of each wing and two dark combs (may look like bands) on each of the front legs.
