Spotted Wing Drosophila IPM Working Group

The invasive species spotted wing drosophila (SWD), Drosophila suzukii, has exploded onto the scene in essentially all states in the northeastern region since the 2011 growing season, causing significant injury to fruit crops in several areas. Unlike many other fruit flies, SWD has the capacity to lay eggs into intact and marketable fruit. Berries are especially vulnerable, but SWD has been reported from many other crops and wild plants.

The SWD IPM Working Group will help 1) identify and prioritize the research and extension needs for SWD in the Northeast for vulnerable crops, 2) develop effective lines of communication with other working groups within and outside the region and with affected industries, and 3) facilitate development of SWD IPM guidelines for the Northeast.
