USA Flag Lymantria dispar (Gypsy Moth): APHIS Adds the Entire State of Maine to the Regulated Area

Contact: Paul Chaloux, Gypsy Moth National Policy Manager, 301-851-2064.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is adding the entire State of Maine to the list of regulated areas for the gypsy moth (GM). This action is being taken in response to Maine expanding the State quarantine to encompass the entire State.

To prevent the further spread of GM, a Federal Order establishes the entire State of Maine as a regulated area. Effective immediately, all interstate movement of GM-regulated articles from Maine must be handled in accordance with the attached Federal Order.

GM is a highly destructive insect of approximately 300 species of trees and shrubs. The GM program prescribes conditions for the interstate movement of regulated articles from GM quarantine areas. The federal and state partnership limits the establishment of GM outside the quarantine area that would result from human-assisted movement of the pest. We appreciate the cooperative relationship with Maine in the effort to limit the spread of this pest.

Under IPPC standards, Lymantria dispar is a pest that is present: only in some areas and subject to official control in the United States.
