Two male SWD, within a raspberry planting, and one female SWD, on the edge of the planting, were caught in traps collected on July 25 in Cayuga County by Julie Carroll, NYS IPM Program, Cornell Cooperative Extension. The raspberries in the planting are beginning to ripen. It is certainly time to plan SWD management strategies to protect berry crops. At this same location, in four traps in a harvested sweet cherry orchard an identified total of 36 SWD were caught, 8 females and 28 males. In one trap, only half of the vinegar flies were counted because it contained over 8,000 individuals. Taking into account the SWD from this trap and doubling those, brings the total estimated count to 45 SWD, 11 females and 34 males. (Accumulated GDD 1416, day length 14:40)

Three male and 1 female SWD were collected in the whole wheat dough combo trap in a blackberry planting in Tompkins County on 7/24/13 by Johanna Elsensohn, Greg Loeb's lab, Dept of Entomology, Cornell University. The traps had been set two weeks prior. (Accumulated GDD 1447, day length 14:40)

Twenty-one male and 12 female SWD were caught in two traps set in the hedgerow near a blueberry planting in Clinton County by Amy Ivy, Cornell Cooperative Extension Association of Clinton County. No SWD were caught in the two traps in the blueberry planting. This finding may underline how poorly the trap bait competes with fruit for SWD's attention. (Accumulated GDD 1344, day length 14:52)

Laura McDermott, Eastern NY Horticulture Program, Cornell Cooperative Extension, reports two male SWD caught in traps set in a blueberry planting hedgerow in Washington County. Traps were collected on July 22. More on SWD management. (Accumulated GDD 1483, day length 14:47)

Laura McDermott, Eastern NY Horticulture Program, Cornell Cooperative Extension, reports four male SWD caught in traps set in one location in Rensselaer County and three male SWD caught at another location. All the traps that caught SWD were set in hedgerows of berry plantings of blueberry and high tunnel raspberry (not day-neutral strawberry, as previously reported) and were collected on July 22. More on SWD management. (Accumulated GDD 1287, day length 14:44)

One male and one female SWD were caught in traps set in a raspberry planting in Livingston County by David Thorp, Livingston County Cornell Cooperative Extension, and identified by yours truly. Last week's extreme heat in western NY may have hampered trap captures while this week's moderate daytime temperature and cool nights may have favored insect activity and trap captures. Keep in mind that traps compete poorly with fruit for SWD. Routine harvest so as not to leave any ripe fruit in the planting is a good tactic against SWD infestation.

Two female SWD were caught in a trap set in a blueberry planting in Seneca County collected on July 17 by Johanna Elsensohn, Research Support Specialist with Greg Loeb, Dept of Entomology, Cornell University. (Accumulated GDD 1325, day length 14:54)

SWD has been caught in a trap set in woods adjacent to a blueberry plantation in eastern Schuyler County by Greg Loeb's lab, Dept of Entomology, Cornell University. One male and one female were caught during the week preceding July 11; four males and four females were caught during the week preceding July 17. The time for concern about this difficult-to-control invasive insect is upon us. Carefully planned strategies for management of SWD should be developed, especially for late summer and fall fruit crops. (As of July 11, accumulated GDD 1247, day length 15:01)

A single spotted wing drosophila male was caught in a trap collected on July 22 in day neutral strawberries in Wayne County by Juliet Carroll, NYS IPM Program, Cornell Cooperative Extension. Berry crops at risk for infestation include day neutral strawberries, blackberries, raspberries, and blueberries. Berry growers in the area should consider putting a management program into place. In addition, a single male SWD was caught in a trap set in sweet cherry at the same location. Sweet cherry harvest is winding down and fruit destined for farm market shelves will benefit from cold temperature storage or display cases. (Accumulated GDD 1374, day length 14:48)

One male SWD was caught on July 1 in Dutchess County, NY by Peter Jentsch's program, Hudson Valley Lab, Cornell University, as reported by Mike Fargione, E NY Hort Program, Cornell Cooperative Extension. The trap was set in a cherry orchard. (Accumulated GDD 990, day length 15:05)
