The data table shows trap counts of adult insects from vegetable fields and a research farm within the Willamette Valley, OR. through July 9th, 2026. See the site code map for approximate locations.
Spotted cucumber beetles are increasing – cabbage looper counts vary by location – view the full report (.pdf below) for details.
Our trap counts feed into a collaborative, multi-crop system called the Oregon Pest Monitoring Network. Their ‘pest forecast tool‘ provides interactive maps and tables to estimate impact based on pest phenology and existing degree day models.
According to a phenology model*, small looper larvae are likely throughout the Willamette Valley (light purple). Large larvae could be present in parts of Josephine, Jackson, Sherman, Gilliam, Morrow, Umatilla, and Malheur counties (teal blue). Scout accordingly. *Toba et al 1973, May 15th biofix, USPest.org
