Aphids and barley yellow dwarf (BYD) have been known in the southern Cone countries of South America (Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay) for many years, but the aphids role as vectors of barley yellow dwarf virus (BYDV) in cereals was not apparent until the late 1960s. The aphid vectors most widely distributed throughout the region are Metopolophium dirhodum (Walker), Sitobion avenae (Fabricius), Rhopalosiphum padi (L.), and Schizaphis graminum (Rondani). BYD was positively identified in 1967 (Brazil) and 1972 (Chile). During 1974/75 and 1975/76 severe BYD epidemics developed, with losses in the range of 10 to 60 %. From
