Mezzalama, M. | Burnett, P.A. (CIMMYT, Mexico, DF (Mexico). Wheat Program)
Isolates of barley yellow dwarf virus (BYDV) were detected by indirect enzyme-linked immunosorbent assay (ELISA). Three monoclonal antibodies, produced against the English MAV-, PAV-, and RPV-like isolates, were used. The plants tested were infected with a range of species of cereal aphids collected from the field. Metopolophium dirhodum (Walker) was a vector of a MAV-like isolate, Sitobion avenae (Fabricius) of MAV-, and PAV-like isolates, and Rhopalosiphum padi (L.) of PAV- and RPV-like isolates. R. maidis (Fitch) did not transmit any BYDV isolates detectable by the monoclonal antiobodies used, but mild symptoms suggested the presence of an RMV-like isolate. A number of mixed infections were detected.
