The buckthorn aphid, Aphis nasturtii Kaltenbach, is one of four species of aphids commonly infesting potatoes, Solarium tuberosum L., in Maine. It is widely distributed over the northeastern part of the United States and is a pest of potatoes elsewhere in the world, including parts of England and Europe. The other three species of potato-infesting aphids in Maine are the green peach aphid, Myzus persicae (Sulzer), the potato aphid, Macrosiphum euphorbiae (Thomas ) and the foxglove aphid, Acyrthosiphon solani (Kaltenbach).
