SWD biology and distribution, trap construction and resources, and insecticide recommendations.
[7/19/2017] SWD trap catch is increasing across the state and we have detected the first Japanese Beetles of the season.
[7/12/2017] During past week, July 3-10th, we observed a significant increase in SWD adults collected at several trap locations in the Twin City Metro area. For example, high catch rates of 70/week were found at Hastings (grapes), with over 110/week/trap observed at Andover. The timing of the increase also coincided with the mid-July increase we saw in 2016. Again, all SWD Trap sites are summarized weekly at: https://www.fruitedge.umn.edu/swdtrap
