Abstract

A statewide survey of commercial vineyards in Virginia (VA), USA was conducted during 2009 through 2011 seasons for the presence of Grapevine leafroll-associated virus-2 (GLRaV-2), Grapevine leafroll-associated virus-3 (GLRaV-3), Grapevine fleck virus (GFkV), and mealybugs. Out of 415 samples (comprising 41 wine grape varieties) from 77 locations (vineyards), GLRaV-2, GLRaV-3 and GFkV were detected in 8%, 25%, and 1%, respectively, and 64% of vineyards were positive for at least one of the three viruses. Samples from 100 wild grapevines of Vitis sp. tested negative for the three viruses, indicating that wild species of grapevines are unlikely to be alternative hosts for these viruses in Virginia. In addition to VA, 21 vineyards from other mid-Atlantic states were sampled. Both grape mealybugs (Pseudococcus maritimus) and Gill?s mealybugs (Ferrisia gilli) were commonly found in VA vineyards. Although regional effect was not significant (P > 0.05), examination of variance showed higher variability of GLRaV-3 incidence at vineyard scale (i.e., within a vineyard) than at a smaller spatial scale (i.e., at sampling site). In addition, the probability of finding a GLRaV-3-infected vine was higher in the presence of mealybugs (P < 0.001) and with increased vine age (P < 0.001). These results also suggest movement of GLRaV-3 by mealybugs in VA vineyards. The high frequency of virus-infected vines emphasizes the importance of clean plant materials as well as management of mealybugs. This is the first study reporting the presence of Ferrisia gilli, GLRaV-2, GLRaV-3, and GFkV in VA vineyards.
