[10/7/2017] Entomologists Eric Burkness and Bill Hutchison have been working with area growers to find soutions to spotted wing drosophila infestations.
[8/23/2017] As we now transition into the peak Fall Raspberry season in Minnesota, it is critical that growers are well prepared with the current IPM recommendations, and strategies to be successful. This is especially true for those producing raspberries in open field situations, but also critical for those production systems in high-tunnels (HT). Here, we offer 5 recommendations necessary to continue to be successful. It has also been encouraging to hear from growers who have had success with this system.
[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
[6/28/2017] Following this year’s 1st catch of SWD in Scentry baited traps on June 12th this year, captures were also reported the week of June 19th, near Northfield and on the St. Paul campus (Dr. Mary Rogers, Horticultural Science). Most important, as of last Monday (6/19), and this week (6/26), SWD were captured in traps at ALL of our 7-county Metro area on-farm locations. Trap captures were still relatively low this week, ranging from zero to 19 per trap, with most traps in the 0-5 range. However, as noted last year, the onset of trap catch (i.e., SWD presence of 1 or more/trap/week) indicates a risk for egg-lay and larval infestations, and time for growers to finalize their management plans for all berry crops this season.

Most important, as of this past Monday (6/19), SWD were captured in traps at all of our 7-county Metro area on-farm locations.
[6/15/2017]The first SWD adults of the season were collected in traps with Trece lures over apple cider vinegar, and in traps with Scentry lures over water on Monday, June 12th, at the Rosemount Research and Outreach Center in Rosemount, MN over fall bearing raspberries.
University cooperators discuss organic management options for control of SWD.
This webinar addresses insecticide efficacy, post harvest residues, resistance management, and strategies to improve control of SWD.
[7/27/2016] SWD counts continued to increase this past week, with major, exponential increases in traps located near Summer- and Fall-bearing raspberry (>1400/trap near Andover). Commercial growers should be well into their IPM and Organic management programs for SWD.
