The results of the survey carried out in 2018 and 2019 on grapevine yellows diseases (“flavescence doreé” - FD and “bois noir” - BN) in Abruzzo Region (Central Italy) are reported. The monitoring (done according to the European Commission Regulation 652/2014) was carried out in more than 200 vineyards. Symptomatic grapevines were detected with visual inspections from late July to mid-September and the presence of phytoplasmas on symptomatic leaves and canes was detected with molecular analyses. The presence of the main insect vectors, Scaphoideus titanus and Hyalesthes obsoletus, was monitored from the end of June to mid-September using yellow sticky traps. The results showed a widespread presence of BN particularly in the provinces of Chieti and Pescara, while FD was not detected. H. obsoletus was found both on bindweed and nettle present at the borders of the vineyards, while the captures of S. titanus were influenced by the phytosanitary management of the vineyards and by the presence of wild grapevines in the surrounding areas. The results were used for the management of the risk and spread of grapevine yellows disease in the Abruzzo Region.
