This field workshop is for the commercial berry grower.
Monitoring for pests, designing an effective pest control program, understanding cultural and chemical SWD management strategies and general troubleshooting will all be part of this workshop.
Dates first trap catch of SWD occurred in the monitoring network. Most occurred in June and early July, with only one in August, on the first.
As of August 7, 2017, all of the 32 SWD trapping sites have caught SWD in 21 counties in New York. To prevent fruit infestation now, susceptible fruit crops need to be protected with an insecticide spray program or have already had exclusion netting in place. Reports are coming in from growers stunned by the level of damage that SWD can cause to their crops, especially blueberries and raspberries. Plantings have been closed.
As of August 10, on average, 200 SWD per trap are being caught in an unsprayed fall raspberry planting at the NYS Agricultural Experiment Station in Geneva, NY. Fruit samples from this planting have, on average, 8 larvae per fruit as found via salt flotation. Each collected fruit yielded a range of 0-8 eggs. These data provide evidence that high pressure from SWD builds during late summer, making it impossible to harvest susceptible fruit that is free of infestation during this time, unless an insecticide program or exclusion netting is in place.
Herkimer County traps caught 10 SWD, 7 males and 3 females, on August 1, 2017. Four traps are being monitored in a blueberry planting, which is still not at peak ripeness. The grower is hoping to get a couple more weeks of picking out of the planting.
Three male spotted wing Drosophila (SWD). Note the spot on each wing, which is on the end of the first vein from the outer edge of the wing.
Traps in Herkimer County are being monitored by Bernie Armata, Herkimer County Cornell Cooperative Extension.
This is the final SWD monitoring network County to catch SWD. All other sites are at sustained catch. The number of SWD caught at research sites is on the rise. Reports of fruit infestation have come in, especially from fruit plantings not being treated with insecticide. Some direct market growers have closed their plantings due to SWD pressure.
At this point in time, if fruit is ripe, it should be protected with an insecticide program:
