Aphids naturally occurring on Plum pox potyvirus (PPV)-positive bushes and trees in heavily sharka-infested plum orchards were tested for their ability to transmit this virus. The aphid species tested were Aphis sambuci L., Callaphis juglandis L., Eucalypterus tiliae L., Chaetophorella aceris L., Macrosiphum rosae L., and Myzus cerasi L. Positive reaction to PPV-antibody (ELISA test) revealed the ability of three species (Aphis sambuci, Callaphis juglandis and Macrosiphum rosae) not formerly known as PPV vectors to transmit the virus to a herbaceous indicator Nicotiana clevelandii x Nicotiana glutinosa. The probability is therefore raised of the virus being transmitted to new host plants, which may be sources for infestation of so-far untouched fruit species
