SWD Updates
[9/6/2018] With the wine grape harvest coming soon, and a recent increase in Spotted Wing Drosophilla (SWD) counts, via our weekly trapping network, growers should be aware of the potential contamination of juice or wine if berries are exposed to SWD just prior to harvest.
[8/3/2018] Although this week’s SWD adult fly captures remain low at Rosemount, moderate to high catches of adult flies continued at the Hastings, Forest Lake, Waverly and HRC sites.
