Abstract: The Spotted Wing Drosophila (SWD) is a recent invasive pest of commercial and home garden fruits, especially, raspberry, blackberry, and blueberry. Oviposition into intact, ripening, soft-skinned fruit leads to small larvae inside the fruit that cause rapid deterioration and loss of marketability. SWD has been an industry “game-changer” as the pest has caused some growers to go out of business or to use more insecticide than consumers expect. I will trace the history of SWD in the U.S. and provide an update on what we have learned about this devastating pest.
