Published on Leave a comment on Suffolk County NY – first report

Five female and two male spotted wing drosophila (SWD) were caught in three traps the week of June 12-19, 2013, in eastern Long Island as reported by Faruque U. Zaman, Cornell Cooperative Extension of Suffolk County, Long Island Horticultural Research and Extension Center. Two traps were in a raspberry plantation at early ripening and one trap was 75 ft. inside the adjacent wooded area. No SWD oviposition or larvae were found after checking ripe raspberry samples from the plantation. (Accumulated GDD 650, day length 15:07)

The first SWD of the season was confirmed on June 19, 2013 by Heather Faubert, University of Rhode Island. A single male was caught in an apple cider vinegar/yeast insert dual trap set up in a cherry tree in Newport County, Rhode Island. Cherries were collected to check for oviposition.

On 17 June, 2013, 4 female and 1 male SWD were collected from two apple cider vinegar traps in Orange County, NY and identified by Peter Jentsch, entomologist, Hudson Valley Laboratory, Cornell University. The male was caught in the trap on the wooded edge, the females were caught in traps placed in a raspberry planting with fruit starting to show color. Fruit will be collected on June 21 and assessed for SWD injury level. (Accumulated GDD 640, day length 15:05)

On June 17, 2013, a single female SWD was found in the SWD trap network maintained by Mary Concklin, Extension Educator - Fruit Production & IPM, University of Connecticut. The trap was in a cherry orchard in Hartford County, CT.  Cherries had no evidence of SWD larvae.

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

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)

Official SWD confirmed 2011 in NY

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.

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.

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.
