A single SWD female was caught on June 24, 2015 in Wayne County at a site in our monitoring network in a trap baited with the standard fermenting whole wheat bread dough. This site is being monitored by Juliet Carroll, NYS IPM Program. Her technician Nicole Mattoon identified the lone female among the other insects in the trap. The trap was located within a summer raspberry planting. Fruit are beginning to ripen at this location. This farm also has June strawberry nearing the end of harvest, sweet cherry, peach, blueberry and day neutral strawberry. It is time to carefully plan out the best strategy for your farm to manage SWD on vulnerable crops. (GDD = 805, day length = 15:20)

A single female was caught at a research site in Orange County using a baited Trécé trap, set during the week of June 15th-22nd by Peter Jentsch, entomologist, Hudson Valley Laboratory, Cornell University. The trap uses a combination lure incorporating both pheromone and kairomone—a feeding attractant. Jentsch examined red raspberry fruit from a 25-count-sample collected on Monday the 22nd (var. Caroline) and no ovipositional stings or egg breathing tubes were found. Read more on The Jentsch Lab blog.

These females are capable of laying eggs, so it is time to get set, get ready, and go protect your fruit crops. June strawberry harvest is winding down, so this crop may not need protection. Summer raspberry is showing ripe fruit now and will be at risk in 2015. Sweet cherry and tart cherry will be at risk, since they may ripen and be harvested over the next few weeks, consider what materials you have in your insecticide programs and make sure that SWD is covered.

The research comparing different lures for catching SWD early is ongoing at three locations in NY - comparisons are being done between a Trécé lure, a Sentry lure, a boosted lure from Trécé, the standard fermenting bread dough (used in the NY monitoring network), Cha Landolt synthetic lure, and apple cider vinegar alone. These research sites aren't included on the SWD distribution map, so don't be confused by Orange County still showing in gray for none found. This means there have been none found in the monitoring network sites in Orange County.
