Spotted wing drosophila adults can be seen cavorting on berries. Populations of this insect are exploding and it will become increasingly easy to see the fruit flies on berries in berry plantings. Tim Martinson, Dept of Horticulture, Cornell University, reports finding SWD on essentially every blueberry on the three bushes in his backyard and I have seen SWD adults on blackberry fruit and day neutral strawberry fruit. It is essential to cull overripe and damaged fruit from plantings and maintain insecticide coverage to protect fruit.
