Acyrthosiphon pisum, commonly known as the pea aphid (and colloquially known as the green dolphin, pea louse, and clover louse ), is a sap-sucking insect in the Aphididae family. It feeds on several species of legumes (plant family Fabaceae) worldwide, including forage crops, such as pea, clover, alfalfa, and broad bean, and ranks among the aphid species of major agronomical importance. The pea aphid is a model organism for biological study whose genome has been sequenced and annotated.
