Sustained catch in Wayne County

Confirmed sustained catch occurred in Wayne County on June 28, 2017 in ripe summer raspberries (2 females caught in two of four traps) and on July 11 in a blueberry planting (1 female SWD in one of four traps).

SWD female caught in Cayuga County on July 8, 2014. Note the large, sclerotized ovipositor.

These traps are being monitored by Nicole Mattoon, IPM field technician, and Taylere Herrmann, IPM summer technician, with my fruit IPM program.

If your berries are ripe and SWD is being caught in your area, it may be time to start insecticide treatments to protect the crop.

Keep in mind the IPM tactics for managing SWD:

  • trapping to know when SWD has arrived at the fruit planting;
  • carefully monitoring the ripening fruit crop;
  • sanitation — immediate disposal of over-ripe or infested fruit;
  • sanitation — clean harvesting fruit;
  • pruning and weed management to maintain good air and sunlight penetration into the planting;
  • protecting the crop with insecticide treatments or exclusion netting;
  • refrigeration of harvested fruit.
