Innovative Technology Targets Spotted Wing Drosophila in Oregon
US · Published Jun 10, 2026
Researchers in Oregon are trialing a new technology called Decoy to combat the spotted wing drosophila (SWD), a pest that causes significant damage to soft-skinned fruits like blueberries and cherries.
Developed by Oregon State University entomologist Vaughn Walton, Decoy employs a fruit-mimicking formula that acts as a behavioral arrestant.

Why It's Important?

The spotted wing drosophila poses a severe threat to fruit growers, particularly in Oregon, where it has significantly increased pesticide use and production costs. The pest can decimate crops within weeks, leading to substantial economic losses. Back-to-back mild winters have resulted in a larger-than-usual population, with trap counts quadrupling compared to normal years. While the Decoy technology offers a promising solution, growers must remain vigilant, as high pest pressure is expected this season. The pest's ability to lay eggs inside fruit makes it difficult to detect and control, raising concerns about crop quality and marketability.
