Abstract

Epidemiology and transmission characteristics of ‘Candidatus Phytoplasma prunorum’ were studied in Austria and Hungary. The investigations showed high infections rates of up to 70% for wild Prunus spp.. Molecular analysis revealed a large congruence of phytoplasma types in wild and cultivated Prunus as well as in Cacopsylla pruni indicating a joint epidemic cycle. In semi-field transmission experiments an inoculation access period of 4 h was sufficient for phytoplasma transmission.
