Studies were conducted to determine the role of Canada plum as a host of the green peach aphid in northeastern Maine and to assess its importance as a source of infestation by the aphid on potatoes. The results relate chiefly to chronological and phenological aspects of the use of Canada plum as a primary host of this aphid; temperature developmental requirements of the aphid on this plant in spring; productiveness of spring migrants of the aphid in thickets and in cages; interrelationships between fall aphid populations on foliage, and egg deposition and overwintering to naturally occurring aphid colonies in spring and summer populations on potatoes.
