  • Historical Gypsy Moth Publications
    USDA. ARS. National Agricultural Library.
    This collection of publications in NAL's Digital Repository provides access to and addresses a number of topics concerning the gypsy and the related brown-tail moths, from biological control methods to tree banding to quarantine practices. The bulk of the documents were published from 1891 to 1923 by various agencies in the area of the initial infestation, including the State Board of Agriculture for Massachusetts, New York, and Rhode Island, but also include some more modern USDA publications.
