History of Gypsy Moth in North America

1900 - Continued Control


This plan worked so well that by 1900 gypsy moths had for the most part vanished from the American landscape. The Massachusetts State Legislature decided that enough had been done and did not seek further funding for the program. The State's Gypsy Moth Commission and Board of Agriculture, who knew better, vigorously protested this decision to no avail. Just as they predicted, gypsy moth resurfaced in Massachusetts soon after and began to spread to surrounding states. In spite of renewed efforts to control the insect (including an attempt at biological control by importing natural enemies from Europe and efforts to replace susceptible trees with less attractive ones), gypsy moth were established in the New England States by 1920. Eradication of the pest was not remotely possible by then, so control of gypsy moth became the goal. By 1922, gypsy moth had moved into New York and soon after spread to New Jersey and Pennsylvania, and then to points North and West.
