Aerial spraying for gypsy moth control: A handbook of technology. Updated version, January 1991
The gypsy moth, Lymantria dispar, is a native pest of the forests of Europe and Asia that was introduced into the United States in Eastern Massachusetts in 1869 and in New Jersey in the 1920's. It is now established in all or parts of the 13 Northeastern States from western Pennsylvania, eastern West Virginia, and northern Virginia to central Maine, and extends into eastern Ohio and central Michigan. In Canada, this pest is established in southern Nova Scotia, Quebec, and Ontario. In addition to existing populations in the generally infested area, 68 isolated infestations have been eradicated since 1982. The effectiveness of these Federal/State cooperative suppression projects using the biological insecticide Bacillus thuringiensis (Bt) and, to a lesser extent, the chemical insecticide Dimilin, are monitored using a computer-based system (Treatment Monitoring Data Base) developed by Twardus. The effectiveness of these projects has been highly variable. It is thought that a large portion of the treatment failures has been due to ineffective aerial application techniques.
