Monitoring Drosophila suzukii Matsumura in Oregon, USA sweet cherry orchards.. Meeting Proceedings. 109:195-196. Interpretive Summary: Spotted wing drosophila is a newly introduced pest of numerous fruit crops that has spread rapidly through much of North America, including areas of extensive commercial fruit production. Trapping with baits is presently relied on as a means of detecting and monitoring the fly, and warning growers of the need to apply insecticides. Researchers at the USDA-ARS laboratory in Wapato, Washington, in collaboration with scientists at the Oregon State University, Hood River, Oregon, evaluated a synthetic chemical lure in traps as a means of early detection of the fly in sweet cherry orchards. They found that the Trappitt dome trap out-caught cup type traps, and the chemical lure out-caught two food type baits used widely in detection programs; apple cider vinegar and a yeast + sugar solution. This information provides growers, pest managers, and extension personnel with improved methods for early season detection of the spotted wing drosophila. The resultant trap catch data can be used for pest management decisions made by growers. Technical Abstract: Drosophila suzukii rapidly became a significant cherry pest in the western United States after it was observed damaging cherries in 2009 in California. It has caused significant damage to ripening cherries in all major USA cherry production districts leading to increased management costs and reduced profits. Cherry producers require good tools that provide information on the need to treat with insecticides. This project presents information on recent studies on attractants and traps for D. suzukii in sweet cherries |
