Gypsy Moth Pest Alert: The gypsy moth has been a primary defoliator of hardwoods in the Northeastern United States since its introduction in 1869. Although Pennsylvania, New Jersey, New York, and New England are generally infested, isolated infestations have been noted in some North Central, Southern, and Western Seacoast States and are now subject to eradication by the USDA Animal and Plant Health Inspection Service.
