Monitoring Information for Spotted Wing Drosophila

Resources to help you determine if there is Spotted Wing Drosophila on your farm or around your home. 

Degree-Day Model - Temperature-based SWD development model produces forecast of SWD activity.  Map should default to a weather station near you and can be changed by clicking another location on the map.

SWD Clock - Provides table of degree-days accumulated so far this season in several western locations; includes comparison to normal and previous seasons' degree-day accumulation.

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.
