Welcome to the Insect Pest Prevention and Management (IPPM) Section at ODA!
survey technician removing GM trap
Survey technicians are in the process of removing gypsy moth (GM) and other invasive insect traps for the 2008 survey season. Each year the IPPM section at ODA conducts a statewide survey for gypsy moth. Early detection of this moth allows ODA and cooperators to eradicate infestations when they are small. Gypsy moth caterpillars have defoliated millions of acres of trees and shrubs in the northeastern United States. Since the late 1970's, small isolated populations of this insect have been detected and successfully eradicated in Oregon.
