All the cereal-feeding aphids are potential vectors of cereal viruses, as indeed are aphids feeding on other Gramineae and Cyperaceae. At least 24 species of aphids belonging to 15 different genera have been shown experimentally to transmit viruses of the barley yellow dwarf group. This paper reviews the biologies of the main Gramineae-feeding genera, with more detailed consideration of the principal vectors of barley yellow dwarf virus. Several of the vectors belong to complexes of species that are difficult to separate, for example Melanaphis sacchari/sorghi, Rhopalosiphum maidis and Sitobion fragariae/miscanthi. These problems of species recognition and their agricultural implications are discussed.
