This site contains information about the gypsy moth. Data is from the USDA Forest Service Cooperative gypsy moth suppression, eradication, and slow-the-spread projects. The Gypsy Moth Digest is maintained by the USDA Forest Service, State and Private Forestry, Morgantown, WV. Use of information from this database should cite the Gypsy Moth Digest as the source.

Aircraft Incidents, 1990-2010—aircraft incidents which occurred during USDA cooperative suppression, eradication, and slow the spread programs nationwide.


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.
