SWD has been caught in traps for two weeks in a row = sustained trap catch at locations in Rensselaer, Albany and Cayuga Counties. The locations in Albany and Cayuga Counties have very low numbers this week, still. The location in Rensselaer County does have higher numbers in week two, 16, versus 2 in week one. The Onondaga County location had reduced SWD numbers, dropping from 21 in week one to 3 in week two, after initiating a spray program.  This may demonstrate the effectiveness of insecticide programs for reducing trap catch or SWD populations in fruit plantings. Thank you to Laura McDermott and Cara Fraver, Eastern NY Horticulture Program, Cornell Cooperative Extension, and to my crew, Jacob Robinson and Tyler Sollenne, for helping us provide this information to the blog. Ripe and ripening fruit should be protected with insecticide sprays if not being clean picked.

One male SWD was caught in a trap set in blueberry in Steuben County the week ending July 31, 2014. The other three traps at this location had no SWD. These traps are being monitored by Stephanie Mehlenbacher, Steuben County Cornell Cooperative Extension. (GDD 1427; day length 14:26)

Two male SWD were caught in traps set in raspberry in Dutchess County the week ending July 28, 2014. One trap set within the planting and the other on the planting edge; each caught a single male. The other two traps at the location had no SWD. These traps are being monitored by Emily Klamberg Cook, Ulster County Cornell Cooperative Extension. (GDD 1766; day length 14:29)

Seven SWD adults have been caught in Yates County the week ending July 24, 2014 in a summer raspberry planting. Most were caught in the two traps set on the edge of the planting, one male in one trap and two males and two females in the other trap. One of the traps set within the crop caught a male and a female, the other trap within the crop had no SWD. All traps are monitored by Gabrielle Brind’Amour in Greg Loeb’s program, Dept of Entomology, Cornell University, Geneva, NY. (GDD 1526, day length 14:42)

Female SWD (left) and male SWD (right), viewed through a dissecting microscope after being drown in an apple cider vinegar trap. Note the serrated ovipositor on the female and the dark single spot on each wing of the male.

A single male SWD was caught in a trap set in blueberries in Ulster County the week ending July 25, 2014. The other three traps at the location were in raspberry and a hedgerow and had no SWD. Traps at this location are being monitored by Jim O'Connell, Ulster County Cornell Cooperative Extension, Eastern NY Horticulture Program. (GDD 1583; day length 14:34)

A single male SWD was caught in a trap set in Wayne County the week ending July 25, 2014. The other three traps in the summer raspberry site had no SWD. Traps are being monitored by Juliet Carroll, NYS IPM Program. (GDD 1329; day length 14:43)

Two SWD females were caught in Erie County, one per site at two sites with four traps each, the week ending July 16, 2014 in summer raspberry and July 19 in fall raspberry. Traps are being monitored by Sharon Bachman, Erie County Cornell Cooperative Extension. SWD is certainly showing up at many locations across NY, placing our delicate and delicious berry crops at risk.

Two female SWD were caught in traps set in Rensselaer County the week ending July 22, 2014. One trap is in an Amelanchier hedgerow and the other is in blueberries. Traps are being monitored by Cara Henderson Fraver in Laura McDermott's program, Cornell Cooperative Extension, Eastern NY Horticulture Program. First SWD trap catch reports are coming in from many sites across NY this week. (GDD 1257; day length 14:44)

Two SWD were caught in traps set in Albany County the week ending July 21, 2014, one male and one female. Traps were set in raspberries and are being monitored by Cara Henderson Fraver in Laura McDermott's program, Cornell Cooperative Extension, Eastern NY Horticulture Program. SWD trap catch remains relatively low across most NY sites this week. (GDD 1433; day length 14:47)

Three female SWD were caught, one per trap, in a Monroe County summer raspberry planting in the week ending July 21, 2014 by Jacob Robinson, summer technician in Juliet Carroll's Fruit IPM Program. The summer raspberries are ripe and nearing the end of harvest. Because this planting is adjacent to a blueberry planting, it will be important to carefully plan an insecticide management program to protect the ripening blueberries.  (Accumulated GDD 1296; day length 14:50)
