First catch Ulster County

At two monitoring sites in Ulster County, SWD was caught in the week ending June 21, 2017. In summer raspberry at one site, 6 SWD (4 females and 2 males) were caught in two traps within the crop and 7 SWD (5 females and two males) were caught in two traps on the edge of the planting — total 13 SWD.

Four female SWD, as seen through a dissecting microscope, that were caught in a Scentry trap. The inset in the middle is a close-up of the females ovipositor.

The other site is small and the four traps are distributed between raspberry and blueberry. Interestingly, SWD weren't caught in the traps set in the blueberries, while in the summer raspberries 18 SWD were caught. 5 females and 2 males in two traps within the crop and 9 females and 2 males in two traps on the crop edge.

This report comes from Jim O'Connell, extension educator, Ulster County Cornell Cooperative Extension.

With reports of sustained catch and double digit SWD being caught in summer raspberry locations, it is crucial to plan your SWD management tactics for the raspberry season and, if raspberries are ripe, begin to protect fruit with insecticides.

Many reports are also being updated to the NY State distribution map, hosted by the Eastern Spotted Wing Drosophila Volunteer Monitoring System, The University of Georgia - Center for Invasive Species and Ecosystem Health. Please note - Suffolk County, Long Island has caught SWD, though the map indicates gray (as of June 27, 2017). All other NY Counties showing gray have not yet caught SWD.
