description

International audience; A four-year monitoring in a vineyard affected with leafroll and first transmission experiments were performed in order to understand leafroll dispersion by the mealybug Phenacoccus aceris. Our data showed for the first time that GLRaV-1 progression was due to the colonisation of the monitored vineyard by infective P. aceris spreading from bordering infected vineyards. Additionally, GLRaV-3 and Grapevine virus A (GVA) were transmitted by first instar nymphs of P. aceris.
