Spotted wing Drosophila
Drosophila suzukii

Spotted wing Drosophila (Drosophila suzukii) is an insect pest. It is a native of Asia and was first detected in California in 2008.

Infestation in cherry initially is manifested by scars in the fruit surface left by ovipositing females. Egg hatch time is very short and larvae soon begin feeding inside the fruit. Within as little as 2 days, the fruit begins to collapse around the feeding site. In California, this pest has been recorded in cherries, raspberries, blackberries, blueberries and strawberries.
