One female spotted wing drosophila (SWD) was caught on June 10, 2013 in Massachusetts, Hampshire County, as reported by Sonia Schloemann, UMass Extension Fruit Specialist, UMass Center for Agriculture. Read more in Massachusetts Berry Notes. A female SWD has the capacity to lay over 350 eggs during her 20- to 30-day life span. The trap was set in the unsprayed edge of a farm with multiple fruit crops, closest to the primocane raspberry field. (Accumulated GDD 515, day length 15:09)

Published on Leave a comment on NY first report – one SWD found

The first reported SWD has been found in the NY trap network - one female in Ontario County. The trap was collected June 11, 2013 and is part of Greg Loeb's trap network. The NY trap network consists of ~230 traps. As of today, no other trap locations have caught SWD, so this find represents ~0.4% of traps catching SWD. The trap consisted of a bait cup containing whole wheat fermenting dough floating in a drowning solution of (9 parts) apple cider vinegar, (1 part) ethanol, (drop) soap in a clear deli cup. The trap was set a few feet into the wooded edge of a blueberry field. Blueberries in Western NY are starting to color - green with a hint of pink/purple. (554 accumulated GDD, day length 15:14)

This particular female was collected in 2011 and sent to USDA SEL for confirmation by Faruque Zaman and Dan Gilrein, Suffolk County Cornell Cooperative Extension, Long Island Horticultural Research and Extension Lab. She was the first officially confirmed SWD from NY in 2011.

Reports have come in from Michigan State University and Rutgers University of positive SWD findings in traps set adjacent to blueberry plantings in Michigan and New Jersey, respectively.

Guidelines for farmers to protect berry crops from spotted wing drosophila (SWD) were recently published in the NY Berry News. The article, Chemical Control of Spotted Wing Drosophila in Berry Crops, by Loeb et al., outlines key approaches for getting the best results from sprays aimed at protecting berries from SWD infestation.

Published on Leave a comment on 2012 NY SWD reports – recap

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.

 

Published on Leave a comment on Trap methods for SWD updated

The SWD monitoring trap instructions have been updated. The new pdf is at the same link as the older version, on the SWD Monitoring page. Using the yeast bait in an ampule floating in the apple cider vinegar drowning solution has resulted in increased numbers of fruit fly captures per trap. So far, though, no SWD have been captured in NY. Stay tuned.

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.

Published on 3 Comments on Who’s monitoring SWD in NY?

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.
