Spotted Wing Drosophila

The Spotted Wing Drosophila (SWD) is a small vinegar fly with the potential to damage many tree fruit crops such as cherries, plums, peaches, some apple varieties and Asian pears, says Dr. David Biddinger, entomologist at the Pennsylvania State University Fruit Research and Extension Center. The greatest potential for damage, however, is probably to the many types of berry crops, especially strawberries and to grapes.
