The 2015 trapping season is underway and first detection of SWD has occurred in Ontario, Canada and New York State. This is certainly earlier than in 2014!

Reports have come in from Southwest Michigan by Rufus Isaacs, Michigan State University, and Middlesex County in Connecticut by Rich Cowles, CT Agricultural Experiment Station of first catch of SWD. As of today, no one in the NY monitoring network has reported trap catch of SWD. Although the catch in Michigan was of several adults, […]
Typically, SWD trap catch continues to increase – hundreds/week – peaking in late fall. In Oregon and Washington, SWD counts in traps have about doubled each week over the last four weeks; the pressure is the highest experienced since SWD’s introduction to that region in 2009. In North Carolina, where SWD arrived in 2010, high […]
