Excerpt
Excerpt: The European gypsy moth (Lymantria dispar) was introduced to North America by Ettiene Trouvelot in the 1860s, and since that time has become an endemic defoliating pest in Canadian and American deciduous forests, mainly east of the Great Lakes (1). The western provinces and states have had occasional infestations, but the importance of the forest industry to the economies of Oregon, Washington State, and British Columbia has made local authorities quick to implement eradication programs to protect the forest resource. Historically, eradication programs have used insecticidal control methods that follow the pattern of pesticide use in North America, beginning with Paris green in the late 1800s, lead arsenate during the first half of the twentieth century, DDT in the post-World War II era, and then carbaryl and trichlorfon until the late 1980s (1). Most recently, a bacterial insecticide, Bacillus thuringiensis var. kurstaki (Btk) has been used widely against the gypsy moth. It is one of the few insecticides whose use is permitted on foodstuffs designated ?organic,? and was mentioned in Rachel Carsons seminal book Silent Spring as an ?important answer to the problems of such forest insects as the budworms and the gypsy moth? (2).
