First and sustained catch in Suffolk County occurred in mid-June. First catch of a single male in a raspberry planting and a single male in a blueberry planting occurred on June 10, 2021. Sustained catch the following week still found only a single male at both locations. These were caught on the two sticky card traps set in the berry plantings.
As of July 7th, when traps were taken down, 39 males were caught in the four traps (two sticky and two jar traps) in the raspberries and 20 males in the four traps in the blueberries. Numbers of SWD no doubt are still on the rise on Long Island.
Traps in Suffolk County were monitored by Faruque Zaman, Suffolk County CCE and Long Island Horticulture Research and Extension Center.
