These isolates are: GPV, transmitted nonspecifically by Schizaphis graminum (Rondani) and Rhopalosiphum padi (L.), a new isolate of BYDV that does not react to the antisera for MAV, PAV, RPV, or RMV; GAV, transmitted nonspecifically by S. graminum and Sitobion avenae (Fabricius), related to the MAV and PAV variantes; PAGV, transmitted T2 - Burnett, P.A.
