This technical bulletin reports the results of an annual survey conducted from 1963 through 1969 of parasitized aphids on potatoes in northeastern Maine, chiefly on Aroostook Farm, near Presque Isle. The authors discuss the role of parasites in control of aphids on potato plants not treated with insecticides and list the primary parasites and hyperparasites reared from potato-infesting species of aphids collected during the survey.
