First catch Livingston County

3 SWD were caught in traps checked on July 6, 2017 — 2 female and 1 male were found in the trap set on the edge of the small blueberry planting at this location.

Checking fruit for larva with salt flotation.

Practice these IPM tactics for managing SWD:

  • trapping to know when SWD has arrived at the fruit planting;
  • carefully monitoring the ripening fruit crop — consider salt flotation assays;
  • 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.

These traps are being serviced by Jennifer Damon for Dave Thorp, extension educator, Livingston County Cornell Cooperative Extension. Nicole Mattoon, IPM field technician, and Taylere Herrmann, IPM summer technician, with the NYS IPM Program are identifying the insects caught in the traps.

First and sustained catch Wyoming County

First catch in a raspberry planting on July 6, 2017 of 3 female SWD in a trap within the crop and 1 female in a trap set on the edge of the crop.

An egg is nestled under the skin of this raspberry, as shown by the white breathing tube (yellow arrow) on the fruit’s surface. The image is highly magnified to see the tiny structure.

Sustained catch on July 12, 2017 of 18 SWD, 8 females and 10 males. Within the crop the trap caught 7 male and 4 female SWD. On the edge of the crop the trap caught 3 male and 4 female SWD.

These traps are being monitored by Don Gasiewicz, extension educator, Wyoming County Cornell Cooperative Extension.

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.

SWD caught at research sites in Oswego County

1 male SWD was caught June 29, 2017 in one of 6 traps set in a 300 acre preserve field research site that has no managed fruit plantings.

1 female SWD was caught July 6, 2017 in one of 7 traps set in a managed cherry orchard (tart and sweet). Harvest is underway at this orchard.

There are no SWD traps in the monitoring network set in Oswego County. These traps are being monitored by Dr. Peter Newell, Assistant Professor, Dept of Biological Sciences, Oswego State University of New York, Oswego, NY, who shared his findings with me. Gabrielle Solomon, undergraduate student working in his lab, services the traps and does the Drosophila identifications.

First catch Essex County

5 female SWD were caught on July 3, 2017 in traps set within a planting of ripe and ripening summer raspberries. These traps are being monitored by Amy Ivy, extension educator, Eastern NY Commercial Horticulture Program (ENYCHP), assisted by Anne Mills, field technician with ENYCHP.

If your berries are ripe and SWD is being caught in your area, it is time to begin management tactics to protect the crop.

First catch in two sites in Clinton County

SWD was confirmed on July 3, 2017 from two sites in Clinton County. 2 female SWD were caught in traps on the crop edge of a summer raspberry planting where fruit is ripe. 3 female SWD were caught in a blueberry planting where fruit are still green, without blush, 2 in traps set within the crop and 1 in the traps set on the edge of  the crop.

These traps are being monitored by Amy Ivy, extension educator, Eastern NY Commercial Horticulture Program (ENYCHP), assisted by Anne Mills, field technician with ENYCHP.

If your berries are ripe and SWD is being caught in your area, it is time to begin management tactics to protect the crop.

First catch at a second site in Wayne County

At a second site in Wayne County, 1 female SWD was caught on July 5, 2017 in four traps set in a blueberry planting. These traps are being monitored by Nicole Mattoon, IPM field technician, and Taylere Herrmann, IPM summer technician, with my fruit IPM program in the NYS IPM Program.

If your berries are ripe and SWD is being caught in your area, it is time to begin management tactics to protect the crop.

Sustained catch in Cayuga County

Confirmed sustained catch occurred in Cayuga County on July 3, 2017 in ripe summer raspberries. 4 SWD were caught in 4 traps, 2 females in traps set within the planting and 1 female and 1 male in traps set on the crop edge. These traps are being monitored by Nicole Mattoon, IPM field technician, and Taylere Herrmann, IPM summer technician, with my fruit IPM program in the NYS IPM Program.

If your berries are ripe and SWD is being caught in your area, it is time to begin management tactics to protect the crop.

First catch Genesee County

2 SWD females were caught on July 3, 2017 in a raspberry planting, 1 in a trap set within the planting and 1 in a trap set on the edge of the planting. These traps are being serviced by Jan Beglinger, extension educator, Genesee County Cornell Cooperative Extension. Insect identification is being done in by Nicole Mattoon, IPM field technician, and Taylere Herrmann, IPM summer technician, NYS IPM Program.

If your berries are ripe and SWD is being caught in your area, it is time to begin management tactics to protect the crop.

First and sustained catch in Erie County

One female SWD was confirmed caught in a trap set within a raspberry and blueberry planting on June 22, 2017 and  the trap set on the edge of the crops had 1 female and 3 male SWD.

Official SWD confirmed 2011 in NY

Another 3 females were confirmed caught on June 28th at this same location in Erie County.

These traps are being monitored by Sharon Bachman, extension educator, Erie County Cornell Cooperative Extension.
