2017 Gypsy Moth Activity Report from Oregon Department of Agriculture

The Oregon Department of Agriculture recently released their 2017 Gypsy Moth Activity Report. 15,135 traps placed throughout the state in 2017 resulted in a total of eleven gypsy moths being caught in Portland, Corvallis, Philomath, Eugene, and Cave Junction. No moths were detected from old sites, including Grants Pass where gypsy moths were trapped four years in a row (2013 - 2016), or in the Asian gypsy moth eradication area in Portland where over 8,000 acres were treated by air in the spring of 2016.
