Genus species: Drosophila suzukii
The spotted wing Drosophila (SWD) is a vinegar or fruit fly of East Asian origin. It made its way into New York by 2011. Today, it has spread throughout most of the continental US. It can directly infest the fruit of many plants, but is most attracted to raspberries, blackberries, blueberries, and other late-season, soft-flesh fruits — cultivated and wild.
SWD deserves notice because, unlike her relatives, which lay eggs on over-ripe or rotting fruit, she can lay eggs inside fresh fruit, often before harvest. After only a few days, the fruit skin becomes dimpled or wrinkled, forming craters in the fruit. Without control measures, late season raspberries, blackberries and blueberries can suffer upwards of 80% crop loss.

- First find in Chemung County
Three SWD were caught in two traps set in and on the edge of a blueberry planting in Chemung County; 2 males and 1 female. These traps are being monitored by Shona Ort, Chemung County Cornell Cooperative Extension. Blueberries are ripe at this location and an insecticide program will be put into place this week. 
- Sustained catch across NY
SWD has now been caught two weeks in a row in Columbia, Livingston, Onondaga, Orleans, Saratoga, Washington, Wayne, and Wyoming Counties. Its time to pay attention to SWD and protect ripe and ripening fruit crops from infestation.

- Tart cherry SWD update
We have caught SWD at all but one of the seven tart cherry sites we are monitoring in Western NY, Wayne and Ontario Counties. Counts are still low and it is likely that the hot and dry weather, as well as insecticide protection, has held things in check. Weather has turned cooler and rains have
