“…GLRaV-3 prevailed where 46% (83/179) of tested grapevines were positive for the virus presence. These data tally with the notion that GLRaV-3 is more common in the Mediterranean (Ahmed et al, 2004;Cabaleiro and Segura, 2006) and GLRaV-1 in the northern viticultural regions of the world (Credi and Giunchedi, 1996;Kominek et al, 2003). GLRaV-2 was found only in 3 out of 179 (1.7%) grapevines.…”

In July 2015, 179 grapevine plants belonging to 16 grapevine autochthonous cultivars were assessed for sanitary status using DAS ELISA test for the presence of: Grapevine fanleaf virus (GFLV), Grapevine leafrollassociated virus 1 (GLRaV-1), Grapevine leafroll-associated virus 2 (GLRaV-2) and Grapevine leafroll-associated virus 3 (GLRaV-3). Furthermore, survey for the phytoplasma presence and laboratory analyses using nested-PCR/RFLP assay was conducted at the beginning of September 2015 on grapevine cultivars which were not positive in DAS ELISA test for the presence of the four viruses. Out of 179 tested plants with DAS ELISA test, 146 (81%) were positive for the presence of at least one virus. The most widespread viruses were GFLaV-1 and GFLaV-3 with approximately 80 % of grapevines infected. Nested-PCR/RFLP assay showed that out of 33 tested samples 2 were positive for the presence of phytoplasmas from 16SrXII group. Sanitation of infected grapevine cultivars is needed in near future.

“…As has been reported previously by other researchers around the world, GLRaV-3 was found to be the most prevalent virus of the complex (Ahmed, et al, 2004;Sharma et al, 2011;Rakhshandehroo et al 2005;Mahfoudhi et al 2008;Hanna et al 2008;Martin et al, 2005;Cabaleiro and Segura, 2006;Coetze et al, 2010), followed by GLRAV-2 and GLRaV-1. These results are contrary to those reported by Fiore et al (2008Fiore et al ( , 2011, who studied other production areas in Chile and found that the most common virus was GLRaV-2.…”

At the end of the study, GLRaV-3 was found to be the most prevalent virus, with 46% of plants infected by this pathogen. GLRaV-2 infected 13% of plants, and GLRaV-1 infected 12%. Considering all three viruses together, the prevalence of infection increased exponentially from 14% of the plants at the beginning of the study period to 68% at the end. The patterns of the spread of GLRaV-2 and GLRaV-3 were mostly along the rows, whereas the pattern of spread for GLRaV-1 could not be determined.

“…Even though adult females are sessile on stems, P. corni nymphs can account for plant-to-plant dispersal of virus, as shown for Pl. citri and GLRaV-3 (Cabaleiro and Segura 2006). Also, these small and flat larvae may be dispersed by wind and by ants, as observed for other scales (Barrass et al 1994;Sforza 2000), as well as by the vinegrower's engines.…”

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 leafrollassociated 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.
