Description: A defoliator of oak and witch-hazel, the oak leaf roller (Archips semiferanus [Walker]) is found in large numbers in northeastern United States and in southwest Ontario, Canada. DDT was formerly used to control this insect. As a preliminary step in finding alternatives to DDT for field testing against the oak leaf roller, four insecticides were evaluated in the laboratory. All four-bioethanomethrin, mexacarbate, phoxim, pyrethrins-caused 90 percent kill with less than 1 pg per insect.
