Survey and Treatment Projects

​​​In 2020 the Oregon Department of Agriculture detected one Asian gypsy moth on Sauvie Island and one European spongy moth near Rainier. ODA plans to mass trap these areas to determine if we have an established population. During May 2019, ODA, in conjunction with the USDA and other federal and state agencies, treated a 45-acre area of Corvallis (Benton County). A ground application of the biological pesticide Bacillus thuringiensis kurstaki appears to have eradicated the European spongy moth population. Spongy​ moths have not been detected in traps in Benton County since 2018 but we will continue our delimination trapping efforts through 2021.​

The USDA completed an environmental assessment for this project prior to treatment. 
The report is available online: USDA's Plant Health Environmental Assessments​​
