notes

The pea aphid is a pest species not only because of its direct suction damage, but also because it is an important virus vector. A. pisum should be understood as a complex of subspecies and incipient species; at least the forms on Cytisus scoparius (and possilby all species of the tribe Genisteae, including Spartium junceum), and on Lathyrus pratensis have the level of species, or at least subspecies (Blackman & Eastop).
