Spotted wing drosophila, Drosophila suzukii, has been confirmed in raspberries from Litchfield, NH. This invasive pest is related to the fruit flies studied in high-school genetics classes across the country, but with a significant difference. The female has an ovipositor with saw-like teeth on it, enabling her to lay eggs in ripe and ripening soft-skinned fruits. This pest has the potential to cause economic damage pre-, during, and post-harvest. Crops that are currently at risk from SWD are bramble fruits, everbearing strawberries, grapes, and late blueberries. George Hamilton, Extension Educator, Agricultural Resources for UNH Cooperative Extension based in Hillsborough County, collected the sample, and Dr. Alan Eaton an Extension Entomologist with the University of New Hampshire made the identification.
