Although Asian gypsy moths are not established in Oregon, they were detected in the summer 2015 in Forest Park, North Portland and in Washington state. Since the Asian gypsy moth was just detected recently, we have a unique and small window of opportunity to ensure the population does not become established in Oregon. If we are able to terminate any early infestations of gypsy moth caterpillars that hatch this coming spring, then we can avoid the species establishing a population in our forest. To help respond to the AGM situation, the Oregon Forest Pest Detector program organized several AGM monitoring workshops in spring 2016 for community members and OFPD program graduates. You can also access the AGM presentation (PDF | 3.4 MB) from the workshop to learn more about the AGM management plan, egg mass identification, and visual survey.
