A new pest attacking healthy ripening fruit: Spotted Wing Drosophila, Drosophila suzukii (Matsumura)

Pest of Concern
Spotted Wing Drosophila fly (Diptera: Drosophilidae; SWD), an exotic pest, has been reported in many states now since its first detection in North America in August 2008. Of the 3000 species of Drosophila, commonly known as vinegar flies, only two have been found to be harmful to crops, of which SWD is one. The SWD can infest and cause a great deal of damage to ripening fruit, as opposed to overripe and fallen fruit that are infested by most of the other Drosophila species. A mailing list has been set up at http://spottedwing.org  to distribute the lastest SWD information.
A seasonal SWD update is also availalbe here.
