| Abstract:
European stone fruit yellows (ESFY) has been reported in Italy with increasing frequency in peach orchards in the provinces of Forlė-Cesena, Ravenna, Rimini and Verona. The discovery of the natural vector of ESFY phytoplasma, the psyllid Cacopsylla pruni, prompted us to investigate the presence of psyllids infected by ESFYP, as well as other potential vectors and alternative hosts, in various orchards in these provinces. The molecular diagnostic method used (PCR-ELISA) made it possible to detect several C. pruni psyllids infected by ESFYP in this area, but no important secondary vectors were found in the peach orchards. Molecular tests were also made on wild plants surrounding the orchards, leading to ESFYP identification in wild Prunus alone. | |
