Identification of Graminella nigrifrons as a potential vector for phytoplasmas affecting Prunus and Pyrus species in Canada
Canadian Journal of Plant Pathology 33 (4), 465-474
Abstract: Prunus and Pyrus species affected with phytoplasma diseases, as well as leafhopper species collected from Prunus and Pyrus fields in Ontario, Canada were tested for presence of phytoplasmas. Preliminary results showed that Graminella nigrifrons is a potential vector for phytoplasma groups 16SrI-W (´Candidatus Phytoplasma asteris'), and 16SrVII-A (´Candidatus Phytoplasma fraxini') to a variety of plant hosts, including peach, apricot, plum and pear. Results showed that G. nigrifrons may be able to transmit both phytoplasma groups simultaneously within the same location and suggest that G. nigrifrons populations appear to have a complex ecology.
