Spotted Wing Drosophila
USDA. ARS. Agricultural Research Magazine.A novel control strategy could be in store for spotted wing drosophila, an invasive vinegar fly species from Asia that attacks more than 100 fruit crops, including blueberry, cherry, blackberry, and grape. Two- to three-millimeters long, the spotted wing drosophila fly first drew attention in 2008 in California. Before long, it had spread to other western states, inflicting losses of 50 to 100 percent in berry crops there. Two years later, it had spread to the eastern United States, wreaking similar havoc and forcing growers to retaliate with intensive insecticide spraying. Researchers, meanwhile, began learning all they could about the invader. One such scientist is Blair Sampson, an Agricultural Research Service (ARS) entomologist who specializes in integrated pest management approaches for small-fruit crops. Sampson is with the ARS Thad Cochran Southern Horticultural Laboratory in Poplarville, Mississippi.

The Spotted Wing Drosophila (SWD) is a vinegar fly of East Asian origin that can cause damage to many fruit crops. This small insect has been in Hawaii since the 1980s, was detected in California in 2008, spread through the West Coast in 2009, and was detected in Florida, Utah, the Carolinas, Wisconsin and Michigan for the first time in 2010. This website will be the central location for dissemination of information about this insect. Check back for updates. This team is also helping to coordinate research projects to understand how best to protect fruit from infestation by this new pest.
