Both vectors transmitted either virus with equivalent efficiency. This is the first record of HpLV transmission by an aphid other than Phorodon humuli. Furthermore, aphids feeding on single infected plants, sequentially on plants infected with one virus and then the other or on co-infected source plants did not influence transmission efficiency of either virus, nor was the frequency of co-transmission affected by the order of virus acquisition. The role of these vectors in carlavirus epidemics in Australian hop gardens is discussed. © 2006 The Authors.
