Spotted wing drosophila is active now!

The Department of Entomology Fruit lab reported that the first significant catch of spotted wing
drosophila (SWD) was found recently in all monitoring sites in the Minneapolis – St.Paul area as well as southeast Minnesota.

 The primary susceptible crop is June bearing strawberries. The first trap catch of SWD was on June 8 but only one adult per week was found until now.

How do I know they're on my plants?

If you have had problems with spotted wing drosophila
in the past or have susceptible fruit in your garden,
consider putting out traps.  Once you have detected
them, then you can take steps to protect your fruit.

If you are growing susceptible fruit in your gardens, including raspberries, blackberries, blueberries, cherries, strawberries, or grapes, 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.

Pest management 

The best approach to managing SWD is through detection, sanitation, and insecticide treatments.
