The Spotted Wing Drosophila
by Tim Baker, regional horticulturist
Earlier this year, I spoke to a group in Trenton about several invasive pests that are either here, or on their way to Missouri. Examples included the Emerald Ash Borer, the Brown Marmorated Stink Bug, and Thousand Canker Disease of black walnut.
Well, now there’s another one: the Spotted Wing Drosophila (SWD). This is a small fruit fly, about 2-3mm long.
