Epidemiological survey reveals primary insect vectors of Xylella fastidiosa in vineyards, highlighting regional transmission risks for winegrapes.

Key Points

Identify the primary leafhopper vectors responsible for harboring and transmitting Xylella fastidiosa, the causal agent of Pierce's disease, within vineyard environments.
Monitored and trapped sharpshooter populations across four commercial vineyards during the 2004 and 2005 growing seasons.
Screened adult specimens of dominant insect species for X. fastidiosa infection using nested polymerase chain reaction assays.
Conducted transmission assays to confirm vector competence and performed DNA sequencing to evaluate bacterial strain homology.
Screening identified X. fastidiosa infection rates of 27% in Oncometopia orbona, 28% in Graphocephala versuta, and 33% in Paraphlepsius irroratus over two seasons.
Controlled transmission experiments confirmed that both O. orbona and G. versuta successfully transmit X. fastidiosa to healthy grapevines.
Genomic analyses revealed that the detected X. fastidiosa strains are genetically uniform and closely match the reference California Pierce's disease strain.
