A baited trap can be made for capturing and monitoring adult SWD flies. As we gain more knowledge about fly behavior, recommendations for making, placing, and servicing traps may change. Alternative trap designs are being explored.
Oregon non‐commercial backyard fruit growers (home gardeners) are encouraged to monitor and report spotted wing drosophila (SWD) flies caught in monitoring traps within their personal gardens. Backyard fruit infested with SWD larvae should also be reported. Participating backyard gardeners are to follow the State of Oregon’s backyard SWD monitoring protocols posted on the SWD website, http://www.spottedwing.org.
