Grapevine virus A (GVA, Vitivirus) was transmitted experimentally by first and second instars of the scale insect Parthenolecanium corni from grapevine to grapevine and to the herbaceous host Nicotiana benthamiana. This is the first report of GVA transmission by P. corni. Grapevine leafroll-associated virus-1 (Ampelovirus) was always present in the donor grapevines and, in every case, GVA was transmitted simultaneously with this ampelovirus from grapevine to grapevine, suggesting possible interactions between the two viruses for transmission.
