Abstrakt: A detailed account of the membrane-feeding behavior of Myzus persicae (Sulzer) is presented. Aphids can regurgitate ingested material during feeding activity. During regurgitation, the flow of material and the pulsing of the sucking pump are as regular as during ingestion, which indicates that the pump can function in either direction. Evidence for regurgitation, along with previous reports indicating that aphids test feed in plant epidermal cells during superficial probes, is interpreted as supporting a hypothesis of virus transmission by regurgitation. It is postulated that aphids acquire virus by ingestion, carry it internally in the alimentary canal, and inoculate it into plants by regurgitation.
