One male SWD has been caught during the week starting May 16 and ending May 22 in one of four traps set in a blueberry planting in Erie County. The trap that caught the SWD was on the edge of the planting next to a woody hedgerow. Sharon Bachman, Erie County Cornell Cooperative Extension, sent in this information today for the traps she is monitoring.
Given the relatively mild winter, we were concerned about SWD being found in NY fruit plantings early this year.
All the traps my program is monitoring, in Cayuga, Onondaga, Schuyler, and Wayne Counties, in berries and tart cherries had zero SWD caught for this week.
If there's no fruit starting to color, there's no need for an insecticide spray.
Be vigilant this year with your June strawberries. Look for rough patches of slightly sunken areas on fruit that appear dull red in color. Later maturing varieties may be at risk this year.

We have a great SWD monitoring network set up this year in Cornell Cooperative Extension! Traps will be set in 24 counties at 36 locations with a total of 122 traps.
Faruque Zaman will be monitoring in Suffolk County, Long Island. Laura McDermott, Amy Ivy, and Natasha Field will be monitoring in the Eastern NY Commercial Horticulture Program region. Peter Jentsch will be working with Laura McDermott in the lower Hudson Valley. Jim O'Connell will be monitoring in Ulster County. Bernie Armata will be monitoring in Herkimer County. Shona Ort will be monitoring in Chemung County. Dave Thorp will be monitoring in Livingston County. Don Gasiewicz will be monitoring in Wyoming County. Tess Grasswitz will be monitoring in the Lake Ontario Fruit Program region. Sharon Bachman will be monitoring in Erie County. I'll be monitoring in Cayuga, Onondaga, Schuyler, and Wayne Counties.
Funding to support this effort comes from Cornell Cooperative Extension Associations and regional programs, the NYS IPM Program, and the NYS Berry Growers Association.
Peter Jenstch, Entomology, Hudson Valley Research Laboratory, Greg Loeb, Entomology, Cornell AgriTech, Paul Hetzler, St. Lawrence County, and others may have research sites that may report findings to the blog.
I will also be monitoring SWD in seven tart cherry orchards in the Lake Ontario and Finger Lakes regions.
SWD findings will be reported to this blog and posted to the SWD NY distribution map. Given the mild winter, it may prove to be an early year for SWD arrival and build up.
