Abstract

Two of the most common leafhoppers present in Chile are the Cicadelli-dae Paratanus exitiosus and Bergallia valdiviana. They commonly occur in vineyards of central Chile, including some vineyards infected by phytoplasmas. The present study demonstrates that P. exitiosus and B. valdiviana can transmit 16SrIII-J phytoplasmas to grapevine and periwinkle plants. This provides improved understanding of the 16SrIII-J phytoplasma epidemiology in Chilean vineyards.
