DescriptionThe sagebrush defoliator was responsible for varying degrees of sagebrush defoliation and mortality over a widespread area in southeastern Oregon, northeastern California, and northwestern Nevada in 1963 and 1964. Severe defoliation sometimes killed sagebrush in a single season. Indications are that the outbreak will continue at least another season. A. websteri has a single annual generation. It is attacked by several species of parasites and predators; the most important of these in California was a Copidosoma.
