Studies were conducted in northeastern Maine to determine seasonal population trends and productiveness of the potato aphid on swamp rose. The results presented and discussed concern chiefly chronological and phenological aspects of the utilization of swamp rose as a primary host of the aphid; time-temperature developmental requirements of the aphid in spring; productiveness of the aphid in caged colonies on swamp rose in spring; population trends of the aphid on naturally occurring, undisturbed swamp rose in spring and in fall; populations of aphid eggs on swamp rose in November and again in mid-April of the following year; and a comprehensive assessment of the probable usefulness of results from surveys of abundance of the aphids or aphid eggs on swamp rose in making advanced estimates of abundance of the potato aphid on potatoes.
