The first European appearance of american grapevine leafhopper (Scaphoideus titanus), which is the vector of Grapevine Flavescence Dorée phytoplasma (‘Ca. Phytoplasma vitis’), were detected in France in 1924. The leafhopper has been distributed since 2006 in Hungary and now it occurs in the whole country, while the first record of the phyt...oplasma was published in 2013.
We studied the distribution of the leafhopper in surroundings of Nagyvárad (Oradea, West Romania) in 2015 and surroundings of Debrecen (East Hungary) in 2016. During the studies 17 sites were sampled. The leafhoppers were found in six Romanian places with relatively low abundances while it occurs in all studied Hungarian sites and two of them showed extremely high frequenncy.
