First catch in Wyoming County

One female SWD was caught in a trap set in a blueberry planting in Wyoming County. The traps were checked on June 25, 2020. The crop is developing nicely. It is essential to keep close watch on the stage of ripeness, to know when fruit becomes susceptible to egg-laying — at pink to purple color. These traps are being monitored by Don Gasiewicz, Wyoming County Cornell Cooperative Extension.

This blueberry planting is immediately adjacent to a large strawberry planting. We know from prior years and reports from other states that when June strawberry harvests are done, the number of SWD caught in traps often spikes. Whether this is coincidence or related to something specific with June strawberries serving as a resource for SWD, we aren’t quite sure. But, suffice it to say, that if you have June strawberries and are also growing blueberries or raspberries or cherries nearby, renovate the June strawberry fields ASAP.
