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)
Are SWD trap counts continued after the first catch? Just wondering if the numbers are staying low or exploding this year. This bug is making me paranoid about spaying too much.

SWD trap counts continue until SWD is caught for two consecutive weeks, or sustained trap catch. Sustained trap catch is used as an indicator that the insect being monitored can be consistently found in the area, rather than the trap catch being indicative of a few individuals that either arrived or emerged from pupae early. As of this date, July 29, 2014, sustained trap catch has not been reached for any location in NY, indicating that we are still in the "early arrival" phase of SWD populations in NY.
