Four male SWD were caught in traps set in a summer raspberry planting in Clinton County in the week ending July 11, 2016, indicating sustained catch. The following week, high numbers of SWD were caught and enumerated on July 19, 2016—10 male and 15 female SWD in the raspberries.
Traps set in the blueberries at this same location only had 2 female SWD in traps checked on July 19. A similar scenario was seen on another farm in New York where raspberry and blueberry are both grown. This would suggest that raspberry is more attractive to SWD and that traps set in raspberry may provide earlier warning of SWD arrival. This also suggests that raspberry is at higher risk of SWD infestation than blueberry.
Traps at this Clinton County location are being monitored by Lauren Fessler, summer intern, who is working with Amy Ivy, Extension Educator, Eastern NY Commercial Horticulture Program and Clinton County Cornell Cooperative Extension.
