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 […]

Living with SWD

Now that spotted wing drosophila is here to stay, berry growers in NY need radically different plans to grow a healthy crop. Marvin Pritts, Professor and Chair, Department of Horticulture, Cornell University, shares strategies for berry growers in his recent article, published in the NY Berry News, Horticultural Strategies for Living with SWD. Details on […]

Northeast SWD Working Group Meeting

On October 30, 2013, in Bridgeton, NJ at the Rutgers Agricultural Research and Extension Center, the Northeast Spotted Wing Drosophila IPM Working Group Meeting will be held from 8:00am to 5:00pm to provide updates on this invasive insect and to set and rank priorities for research, extension, education, and regulatory needs to address its impact […]

SWD on the National Scene

Typically, SWD trap catch continues to increase – hundreds/week – peaking in late fall. In Oregon and Washington, SWD counts in traps have about doubled each week over the last four weeks; the pressure is the highest experienced since SWD’s introduction to that region in 2009. In North Carolina, where SWD arrived in 2010, high […]

Do my fruit have SWD?

Suggested ways for checking fruit for SWD infestation, include looking for egg breathing tubes, finding leaking pinholes, and floating out the larvae. Egg breathing tubes You’ll need a good pair of eyes and 20x magnification. Fruit on which this technique works fairly well include blackberry, cherry, black raspberry, dark plum and grape varieties, and probably […]

SWD easily found now

Spotted wing drosophila adults can be seen cavorting on berries. Populations of this insect are exploding and it will become increasingly easy to see the fruit flies on berries in berry plantings. Tim Martinson, Dept of Horticulture, Cornell University, reports finding SWD on essentially every blueberry on the three bushes in his backyard and I […]

SWD in plums

I have begun examining plums collected in the Finger Lakes and Lake Ontario regions and, to date, have found evidence of oviposition only in samples collected in the Finger Lakes region. As populations of SWD build during late summer and plums ripen on the tree, fruit may be at increasing risk. Which plum varieties are […]

Black cherry hosts SWD

The forest and woodland tree, black cherry, Prunus serotina, is another SWD-preferred wild host. This tree grows in forests and landscapes throughout the Northeast and is native to North America. On Long Island, recent inspections by Faruque Zaman, Suffolk County Cornell Cooperative Extension, showed that over 90% of its fruit were infested with SWD. On […]

Organic Workshop

On August 26, from 5:00 to 7:00 pm, at Westwind Orchard, 215 Lower Whitfield Rd., Accord, NY 12404, a workshop featuring organic management tactics for SWD will be held. Attend to learn about efficacy of organic-approved pesticides, use of exclusion netting, and key cultural practices to reduce SWD infestation of fruit. Registration fee is $10/person […]
