Outbreaks of the Spruce Budworm, Choristoneura fumiferana (Clem.), have persisted in the northeastern U.S. for more than a decade. Recently the outbreak has expanded from Maine into New Hampshire, New York and Vermont. Large acreages have been treated with insecticides in the last few years. A variety of insecticides are registered for use with the Environmental Protection Agency (EPA), though not all are being used (USFS 1978).
