From 1984 to 1986 isolates of barley yellow dwarf virus (BYDV) were identified in small grains collected from three cereals management regions of Pennsylvania. Of 300 plants, 82, 19, 9 and 4 were infected with isolates resembling PAV, RPV, MAV, and RMV, respectively, based on enzyme immunoassays and aphid transmission bioassay tests. Of these plants, 16 % were infected with two isolates, suggesting that infection resulted from inoculation by two aphid species, or by dependent virus transmission from doubly infected source plants. Only 5 % of 329 alate Rhopalosiphum padi (L.) and Sitobion avenae (Fabricius) collected in the field from
