Integrated Pest Management of Spotted Wing Drosophila in North Dakota (E1715, Revised June 2018)
Spotted wing drosophila (SWD) is a vinegar fly that was first confirmed in ND in 2013 as an invasive pest of soft-skinned fruit crops. The SWD lays its eggs in healthy, ripening fruits. Then larvae hatch from eggs and feed on the fruit causing spoilage. Identification, life cycle and pest management strategies are discussed.
