dc.description.abstract |
Since the discovery of aster yellows phytoplasma on grapevine in South Africa in 2006, a concerted effort by various research
groups to identify the vector(s) was co-ordinated by Winetech. This included qualitative and quantitative surveys for two years of
leaf- and planthoppers occurring in vineyards in affected areas, testing specimens of leaf- and planthopper species for the presence
of aster yellows phytoplasma with PCR, transmission experiments, and relating presence of leaf- and planthoppers in the field to
the time of disease transmission. Twenty-eight leaf- and planthopper species/species groups have been recorded from vineyards in
aster yellows-infected regions. The four most abundant species/species groups were Acia lineatifrons (Naudé), Austroagallia spp.,
Cicadulina spp. and Mgenia fuscovaria (Stål) (Hemiptera: Cicadellidae). Austroagallia spp. and M. fuscovaria repeatedly tested
positive for the presence of AY. Results of transmission experiments and a field trial to determine leaf-/planthopper abundance in
vineyards along with time of transmission in the field suggest that M. fuscovaria is a vector of aster yellows phytoplasma in South
Africa. The concerted effort between industry and researchers allowed for fast identification of a potential vector of aster yellows
phytoplasma in South Africa. |
