Spotted Wing Drosophila

Spotted wing drosophila (SWD) is an invasive pest of many soft-skinned fruit crops, including raspberries, blackberries, grapes, cherries, blueberries, and others. It was first found in Wisconsin in 2010, and by now is expected to be in all counties of the state.

Current Research Projects Include (2017-2018):

  • SWD spatial and temporal movement within and around raspberries
  • Tart cherry varietal susceptibility to SWD
  • Potential native enemies for SWD in Wisconsin
