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.

- Early spring food for pollinators
Native, non-weedy, shrub willow blooms in early spring, a time that is critical for pollinators because of the low availability of food sources. Shrub willow supports a large diversity of pollinators that feed on its abundant pollen. Research has shown that wild bees can be an important component of crop pollination. Also, diversified landscapes that […]
- Hummingbirds may reduce SWD
Research in raspberries at Cornell AgriTech over the last four years has shown promise as an alternative tactic to reduce the impact of SWD on berries. As described in a previous blog posted in 2014, Hummingbirds, these birds may indeed enjoy eating SWD. Preliminary data analysis for 2018 shows that when SWD numbers are very low […]
- Spotted lanternfly found in two counties in NY
The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today confirmed that spotted lanternfly (SLF), an invasive pest from Asia, has been found in Albany and Yates counties. A single adult insect was discovered in a vehicle in the Capital District. In addition, a single adult insect was reported on a private […]
- Use salt flotation to check for SWD
Effective use of salt flotation will help you determine if your fruit are infested with SWD and if your spray program is working. It also will give you a perspective on what your customers may find when they take the fruit home to eat fresh or to make pies, jellies, jams and preserves. I learned that variations […]
