A single male SWD was caught on July 16, 2014 in a yeast baited apple cider vinegar trap set in a blueberry planting in Seneca County by Gabrielle (Gabe) Brind'Amour in Greg Loeb's program, Dept of Entomology, Cornell University, Geneva, NY. The population of SWD is still at very low levels in NY, providing an opportunity for growers to practice sanitation or clean-picking of fruit that is nearing the end of the harvest period. This early alert provides an opportunity to review available insecticides and plan a program for at-risk fruit that is beginning to ripen. (GDD 1270, day length 14:55)
