Based on the classification of W.R. Rochow, only MAV-, PAV- and RPV-like strains are known to occur. Although Rhopalosiphum maidis (Fitch) and Schizaphis graminum (Rondani) are present, the RMV- and SGV-like strains have not been recorded. The epidemiology of BYDV is influenced principally by local cropping patterns and the relative occurrence and importance of holocyclic and anholocyclic forms of the main aphid vectors.
