Lethal and Sublethal Effects of Aldicarh on Two Potato Aphids (Homoptera: Aphidae):Myzus persicae(Sulzer) andMacrosiphum euphorbiae(Thomas)

Abstract
Field tests conducted in 1982 and 1983 indicated that a minimum of 30 h was required to reach a 50% mortality level when winged green peach aphids, Myzus persicae (Sulzer), are exposed to aldicarb-treated potato plants. Surviving aphids are not expected to be efficient vectors of persistent viruses because of a significantly reduced ability to fly and to probe. Tests done with the common potato aphid, Macrosiphum euphorbiae (Thomas), yielded similar results.
