Abstract

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.
