Organic insecticides

Organic-approved insecticides for SWD include Entrust Naturalyte and Entrust SC (active ingredient spinosad.) Both require the 2(ee) recommendation for use against SWD. You must have the 2(ee) in hand when using the insecticide for SWD. The spinosads are good to excellent, but only 3 applications per crop year are allowed. Download the 2(ee) for Entrust […]

SWD monitoring video

The July 16, 2014 You Tube video from the Finger Lakes monitoring network shows male and female SWD alongside other fruit flies. Check out these videos to hone your skills at differentiating other fruit flies caught in traps from spotted wing Drosophila. Anna Wallingford, Postdoctoral Research Associate in Greg Loeb’s program, Department of Entomology, Cornell […]

First v. Sustained Trap Catch

Sustained trap catch is a milestone often used in IPM for timing management tactics against insect pests. Insect traps in the SWD monitoring network are checked once per week until adult SWD have been caught for two consecutive weeks at that location, indicating sustained trap catch. On the blog, we post SWD first catch reports. […]

Female imposters

Distinguishing female SWD from other fruit flies caught in traps can prove challenging. Look alike reports to help with identification have come in from Faruque Zaman, Long Island Horticultural Research & Extension Center, Riverhead, NY and Anna Wallingford, NY State Agricultural Experiment Station, Geneva, NY. Faruque’s pictures are below. Anna’s videos are at Finger Lakes […]

Monitoring in NY

SWD traps are being set out across NY in berry plantings by Cornell Cooperative Extension (CCE) personnel for the 2014 monitoring season. Trap catch results from the following counties will be reporting to the NY distribution map: Albany, Cayuga, Chautauqua, Chemung, Clinton, Columbia, Dutchess, Erie, Herkimer, Livingston, Monroe, Niagara, Onondaga, Ontario, Orange, Orleans, Rensselaer, Saratoga, […]

Videos to Monitor By

Videos of 2014 SWD trap contents! This year’s monitoring has begun and Anna Wallingford, Postdoctoral Associate in Greg Loeb’s lab at the Experiment Station in Geneva, created a youtube channel, Finger Lakes SWD monitoring, for weekly video updates (every Monday) on what the Loeb lab is finding in traps in and around Geneva. The videos will […]

Alerts & Protecting Fruit

No SWD has been reported, as of June 11, 2014, from any of the monitoring locations in New York. Any confirmed first trap catch SWD findings will once again be posted on the blog. Current guidelines for managing SWD are to begin insecticide applications on vulnerable crops when fruit are ripening. Late-season blueberries, blackberries and fall […]

Where is SWD found?

As we gear up for our 2014 monitoring efforts in New York, reports are circulating of new places this invasive and destructive fruit fly is being found. From February through May, 2013, Drosophila suzukii was found for the first time in southern Brazil. Closer to home, spotted wing Drosophila is found in the Canadian provinces to […]

Frozen or baked SWD?

As we emerge from the clutches of a long and very cold winter, we’re pondering if SWD was killed off…as were many fruit buds in New York. A study in Japan (Kimura 2004) investigating cold and heat tolerance of fruit flies included SWD. Interestingly, SWD is distributed in all three of the climatic regions in […]

Economic impact survey

The Southern and Northeastern SWD IPM working groups developed the 2013 SWD Economic Impact Survey to assess the impact SWD is having on farmers and fruit production in the Eastern US. Survey results will support the prioritization and justification of research and extension efforts on SWD. Participation is voluntary and anonymous—the more farmers completing the […]
