On June 6, 2017 one female SWD was identified in a monitoring network trap set last week in the wild shrubs at the edge of a red raspberry planting in Orleans County. This report is coming in from Tess Grasswitz, entomologist and educator with the Lake Ontario Fruit Regional Extension Program. She checked another set of SWD traps in raspberries and one set in blueberries (both in Niagara county), which were negative for SWD.
Stay tuned and stay prepared.
Insecticide sprays are not warranted unless fruit is ripe. Please keep close watch on June strawberries this year, as it appears to be an early year for SWD and a slow year for crop development, which may place this crop at risk. More on SWD management coming soon.
