The spruce budworm, Choristoneura fumiferana (C1em. ) has been periodically responsible for severe damage to fir (Abies balsamea) and spruce (Picea spp. ) stands in Maine. A severe outbreak of this serious insect pest between 1910 and 1919 killed about 28 million cords of fir and spruce. In 1954, a localized area of about 20,000 acres of spruce and fir forest was aerially sprayed with DDT; in 1958, 302,000 acres in northern Maine were sprayed. Maine Fish & Game studied the effects of DDT spraying on fish populations in the treated area.
