traps at the Rosemount Research and Outreach Center. If you are growing susceptible fruit in your gardens, including raspberries, blackberries, blueberries, cherries, strawberries, or grapes, be sure to set out traps to determine when SWD is first active in your area. SWD is a very destructive invasive insect pest that can severely damage untreated susceptible fruit crops.

The best approach to managing SWD is through detection, sanitation, and insecticide treatments. For more information on SWD see Spotted wing Drosophila in home gardens.
