The efficiencies of seven clones of Rhopalosiphum padi and five clones of Sitobion avenae (originating from Greece and the United Kingdom) as vectors of barley yellow dwarf virus (PAV-like isolate) were evaluated at 5, 10 and 15 degrees C. When inoculation took place at 5 or 10 degrees C, clones of R. padi differed in their ability to transmit. At 15 degrees C there were no differences in the vectoring ability of different clones. For S. avenae, there were no interclonal differences in the transmission efficiency at any of the temperatures. The epidemiological consequences of differences in virus transmission at different temperatures are discussed.
