Two female SWD were caught on the edge of a raspberry planting near Lake Ontario, one in each of two traps checked on June 5, 2019. These traps are being monitored by Ryan Parker and Juliet Carroll, NYS IPM Program, Cornell Cooperative Extension.
Fruit set is starting and bloom is ending in this planting. There is no need to treat with SWD-targeted insecticides at this point in time. Whenever plants are still blooming, protect pollinators by avoiding insecticide use during bloom.

For those farms where June strawberries are approaching harvest or where harvest is underway, this crop will be at risk this year. It is relatively easy to use red or yellow sticky cards to monitor for male SWD in strawberry plantings of other fruit plantings. Set the sticky card traps on the edge of the planting where it is convenient to read them daily. Here’s one place you can order trap and lure supplies – Great Lakes IPM, www.greatlakesipm.com/.
Because trap catch in New York is early this year, many crops that typically escape injury may be at risk of infestation.
A blog with comprehensive coverage of SWD management will be posted next week. In the meantime, consult Cornell Fruit Resources SWD Management, fruit.cornell.edu/spottedwing/management/. Refer to the Cornell Guidelines, cropandpestguides.cce.cornell.edu/.
Commercial growers should have the 2019 versions of the Berry Crops, Tree Fruit, or Grape Guidelines.
