Abstract

An assessment of toxicological responses among the Choristoneura species occidentalis, viridis, and fumiferana indicated that within-species variation in response to acephate may be as large as between-species variation. Studies of C. occidentalis sibling groups suggest that allozyme variation at the second esterase locus may be related to differential sensitivity to acephate. Use of genetic markers to forecast population response in control programs is discussed.
