On August 19, a trap set in a black currant planting by Paul Hetzler, Cornell Cooperative Extension of St. Lawrence County, caught 3 male and 1 female SWD. The trap had only been out since August 17th. SWD damage in blueberries has been seen in St. Lawrence County, with approximately 40% damaged fruit found in one planting. Last year, at this date, the same blueberry planting had 100% fruit infestation. (Accumulated GDD 1632, day length 13:48)
