Sustained catch in Tioga County

At two sites in Tioga County, SWD has been caught two weeks in a row as of June 20, 2017, indicating established populations. Numbers caught are still low. Four SWD, 1 female and 3 males, in one trap set outside a high tunnel of raspberries. Three SWD, 2 female and 1 male, in one trap set on the edge of an open-grown raspberry planting.

Tiny threads of the SWD egg breathing tubes indicate where an egg was laid in a raspberry.

These traps are being maintained by Margaret Ball, extension educator, Tioga County Cornell Cooperative Extension. The insects caught are being sorted and identified by Nicole Mattoon and Taylere Herrmann in my fruit IPM program.
