On June 18, 2021, a single male was caught in a jar trap set on the edge of a blueberry planting in Chemung County. Three other traps at the site caught zero SWD. These traps are being monitored by Liz Alexander, Chemung County Cornell Cooperative Extension.
Blueberries are still sizing up. Most are still green in the central and western NY plantings I've visited this week. Some early varieties have started to show signs of color in more southern locations. Because blueberries are less susceptible than brambles and cherries, trap catch of a single SWD doesn't signal time to treat. And certainly not if fruit aren't ripe and softening.
Let's take this opportunity, when SWD numbers are still very low, to get ready for SWD management in this crop with the recap below.
