Transmission tests with Rhopalosiphum padi and R. maidis were used to assess incidence of barley yellow dwarf virus in cereal and grass specimens collected in surveys over the eastern Darling Downs and Lockyer district of Queensland. Up to 20 percent incidence was found in randomly sampled grazed oats, but incidence in wheat was less than 1 percent. Bromus catharticus was shown to be a perennial host of PAV and R. padi. RMV incidence in Urochloa panicoides was up to 60 percent in early summer and Paspalum dilatatum was a perennial host of RMV.
