Updates from Global SWD Research

Spotted wing drosophila (SWD) is native to South East Asia. It was first recorded as an invasive species in Hawaii in 1980, and in both California and parts of Europe in 2008. Since then it has spread rapidly throughout temperate North America and Europe, mainly due to global trade combined with an initial lack of […]

SWD egg laying – extreme drought & heat

The earliest ever arrival in New York State of this fast-reproducing insect rang alarm bells in anticipation of heavy infestations in early or mid-season berry crops that often escape damage. However, larval infestations have been curiously low in summer raspberry and blueberry crops sampled in many areas, including the Finger Lakes region. We suspect that […]

Lure test results for SWD traps

Figuring out which SWD trap and lure works best has been an ongoing project for many in the Northeast and across the US and Canada. Below are summarized results from Rich Cowles, Connecticut Agricultural Experiment Station, Greg Loeb, Cornell University, and researchers at the University of Guelph, Ontario, Canada. From Greg Loeb In 2015 trials […]

SWD Stakeholder Survey

The Sustainable Spotted Wing Drosophila (SWD) Management for US Fruit Crops project, funded by NIFA, needs your help. This five-year project is developing national research and extension approaches to minimize the impacts of SWD. They include: new management tactics and programs expanded pesticide registrations for SWD information and training on SWD for growers, extension agents, […]

What to do about SWD-infested fruit?

The SWD monitoring network Counties are all positive for SWD as of last week, August 28, 2015. A lot of SWD are being caught in traps in research sites now with population numbers expected to climb into the thousands before frost knocks them back and forces them into winter diapause. Reports are coming in of […]

Where else can SWD live?

A list of non-crop host plants supporting spotted wing Drosophila in North America is now available online. The guide to non-crop host plants used by spotted wing Drosophila (SWD) has just been published by Oregon State University and compiles information from collections made in Michigan, New York, Florida, California, Oregon, Washington and British Columbia. The […]

2014 Impact Survey

Tell us how SWD affected your fruit farm in 2014. Dear berry growers, Dr. Hannah Burrack in the Department of Entomology at NC State is coordinating the effort again this year to estimate the impact of spotted wing drosophila (SWD) on fruit crops in the Eastern USA.  This information is very valuable for a number […]

Monitoring network wrap-up

The SWD Monitoring Network was once again a success! A big “THANK YOU!” goes out to the 18 Cornell Cooperative Extension and Cornell University scientists who made the network possible in 28 Counties in NY. Funding for the network was provided in 2014 by the NY State Berry Growers Association, the Department of Entomology, Cornell […]
