摘要：

The relationships between the planthopper Hyalesthes obsoletus, its herbaceous host plants (nettle and bindweed), and "bois noir" phytoplasma strains (tuf-type) were studied in five different vineyard areas of the Marche region (Italy). Stolbur phytoplasma was detected by molecular analysis of planthoppers and of their host plants. These planthoppers were caught from bindweed and nettle and separated according to sex. Their mean rates of infection varied from 22.5% to 44.2% in samples from bindweed, and from 7.7% to 14.3% from nettle. All the H. obsoletus from bindweed harboured the tuf-type II, with tuf-type I predominant in planthoppers on nettle.
