Spotted wing drosophila
(Drosophila suzukii)
Overview
Spotted wing drosophila (SWD, Drosophila suzukii) is a fruit fly that was first found in the United States in 2011. Female SWD lay their eggs inside soft-flesh fruits like raspberries, blueberries, blackberries and grapes. Infestations have caused total loss of harvest, but losses between 20% and 60% are more typical, even with intensive pest management.
Research Connection
MITPPC researchers are working on the problem from many angles – evaluating the economic impact to Minnesota; using new drone technology to evaluate flight migration patterns of SWD; and searching for sustainable management alternatives. The information they obtain will help berry growers across the state.
