Category: 2019 trap network

One female SWD was caught in both of the raspberry plantings where traps are set in Ulster County. These traps, checked on June 5, 2019, are being monitored by Jim O’Connell, Cornell Cooperative Extension Association of Ulster County.

The farms grow both raspberries and blueberries. Raspberry fruit is still hard and green. Therefore, there is no need to treat with SWD-targeted insecticides at this point in time. Since 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. 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.

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.

A single male and a single female SWD have been confirmed from traps set within a floricane raspberry (fall raspberry) planting in Putnam County, on June 3, 2019.  These traps, part of the Eastern NY Commercial Horticulture Program’s network, are being monitored by Michael Principe, Putnam County Master Gardener Program.

A single SWD was caught in Erie County in a trap set on the edge of a blueberry planting. Blueberries at this site are blooming. No susceptible fruit is in the area...yet.

The trap was checked on May 30, 2019 by Sharon Bachman, Erie County Association of Cornell Cooperative Extension.

It's likely to be an early year for SWD, with all susceptible fruit being at risk, regardless of how early it's fruiting season is.  Stay tuned to the SWD blog, and to your fruit plantings.

One male SWD was reported found in Albany County today, June 3, 2019. The trap containing the SWD male was set in the hedgerow near summer raspberries, which aren’t blooming yet.

This report is from Natasha Field, Field Technician, Cornell Cooperative Extension, Eastern NY Commercial Horticulture Program.

A single female SWD was caught in a trap set within a summer raspberry planting in Schuyler County on May 31, 2019. Raspberries aren't yet blooming, though the inflorescence has grown out from the canes.

Yes, it looks like it may be an unforgiving year for SWD in 2019. The insect has arrived early and weather conditions have been favorable for continued development across most of New York — mild temperatures, humid, moist, and rainy conditions.
