Potential insect vectors and alternative host plants of the phytoplasmas associated with grapevine yellows (GY) were surveyed in the Fynbos and Succulent Karoo biomes in the Western Cape, South Africa. Aster yellows phytoplasma (16SrI-B), which has been reported infecting grapevine in three regions in the Western Cape, was identified in a plant species belonging to the Aizoaceae. Other phytoplasmas were detected from species belonging to the Brassicaceae, Montiniaceae, Proteaceae and Zygophyllaceae and in a few insect specimens. The information will be used to confirm the insect vector status and the role of the plant species identified as alternative host plants in controlled transmission experiments.

Abstract
Potential insect vectors and alternative host plants of the phytoplasmas associated with grapevine yellows (GY) were surveyed in the Fynbos and Succulent Karoo biomes in the Western Cape, South Africa. Aster yellows phytoplasma (16SrI-B), which has been reported infecting grapevine in three regions in the Western Cape, was identified in a plant species belonging to the Aizoaceae. Other phytoplasmas were detected from species belonging to the Brassicaceae, Montiniaceae, Proteaceae and Zygophyllaceae and in a few insect specimens. The information will be used to confirm the insect vector status and the role of the plant species identified as alternative host plants in controlled transmission experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
