Aphids are reported to be vectors of the most serious viral pathogen of the drupaceous species plum pox virus (PPV), but there is little direct experimental evidence of this. PPV (serotype M) is widespread in peach orchards even where there are severe control measures. Laboratory bioassays were conducted to study, under controlled conditions, the ability of Brachycaudus schwartzi (Börner) and Phorodon humuli (Schrank) to transmit PPV (serotype M). The results have shown that all the peach trees tested had evident symptoms of sharka and were positive to the RT-PCR analysis, confirming the ability of these two aphid species to transmit the virus.
