Surveys on grapevine yellows and insect vectors in Hungary
Surveys were carried out in Hungarian vineyards on grapevine yellows. Only Stolbur phytoplasma (EPPO A2 List, causing bois noir on grapevine) was detected both in diseased grapevines and in its insect vector Hyalesthes obsoletus. H. obsoletus was found with relatively low population density on grapevine but in high density on nettles (Urtica dioica). During these studies, Scaphoideus titanus (vector of grapevine flavescence dorée) and Oncopsis alni (vector of Palatinate grapevine yellows) were not found.
