Insight on when SWD might be found in NY can be obtained from this 2012 table of SWD trap captures and reports of larvae in fruit that came in from scientists last year. Note, the first trap captures in Suffolk County that occurred in March 2012 are not reflected in the table. In the 2013 growing season, so far there have been no trap captures in Suffolk County. Check the 2013 NY distribution map for more info.

The NY distribution map published in September 2012, based on the reports received. SWD is now presumed distributed throughout NY.


As of June 4, no SWD have been caught in traps in Maine, Rhode Island, Connecticut, New York, or Pennsylvania, in the US, nor in Ontario, Canada, as reported on the weekly Berry Call.

Scientists at Cornell University have set traps in NY to monitor for the invasive spotted wing drosophila (SWD). As of June 7, 2013 no SWD have been found in any traps. We are posting data directly into a NY distribution map that is linked on Cornell Fruit Resources and NYS IPM websites. The Cornell University SWD team includes Art Agnello, Greg Loeb, Peter Jentsch and me. The Cornell Cooperative Extension team includes Amy Ivy, Bernie Armata, Betsy Burgeson, Dan Gilrein, Dave Thorp, Debbie Breth, Emily Cook, Faruque Zaman, Ginny Carlberg, Jim O'Connell, Jeff Miller, Kat Loeck, Kevin Iungerman, Laura McDermott, Mike Fargione, Paul Hetzler, Sharon Bachman, and Stephanie Mehlenbacher.
