First find in Chemung County

Three SWD were caught in two traps set in and on the edge of a blueberry planting in Chemung County; 2 males and 1 female. These traps are being monitored by Shona Ort, Chemung County Cornell Cooperative Extension.

Blueberries are ripe at this location and an insecticide program will be put into place this week.

Quick Guide to Berry Insecticides for SWD

Two male SWD on a blueberry, in early September 2013. SWD populations typically build to very high levels in late summer.

Although the hot and dry weather has compressed fruit maturity such that early-, mid-, and late-season blueberries are ripening almost simultaneously, this weather will also keep SWD population growth somewhat suppressed. ...but don't count on the weather to protect your fruit. SWD populations will continue to build through early fall until reproductive diapause sets in around October.
