Flavescence doree (FD) has been defined as the disease that is caused by a phytoplasma belonging to group 16SrV (elm yellows) and transmitted to plants by the insect Scaphoideus titanus. We investigated the transmission of FD agent by S. titanus in a vineyard located in Veneto region in 1996 to determine which phytoplasma(s) may be transmitted in this region. Group 16SrV-C phytoplasma was detected and identified in field-collected S. titanus adults, in plant of grapevine ( Vitis vinifera cv. Gamay) and broad bean ( Vicia faba cv. Arla) that had been fed upon by the insects. No evidence of experimental transmission of phytoplasma belonging to 16SrI-B subgroup phytoplasma by S. titanus has been observed.
