Detection of Grapevine A vitivirus in Tunisian grapevines

EPPO Bulletin, 2001
Grapevine A vitivirus (GVA), Grapevine B vitivirus (GVB), Grapevine leaf‐roll associated closterovirus 3 (GLRaV3) and Grapevine fanleaf nepovirus (GFLV) were detected by DAS‐ELISA in samples of grapevine showing symptoms of rugose wood from different viticultural areas of Tunisia.

Biologie de la vection de l'ampélovirus GLRaV-1 et du vitivirus GVA par la cochenille Phenacoccus aceris

, 2016
L’enroulement de la vigne cause des pertes de rendement et de la qualité des vins au niveau mondial. Il est causé par quatre espèces de Grapevine leafroll-associated virus(GLRaVs) ; GLRaV-1, -2, -3, -4-like. Si le GLRaV-2 (genre Closterovirus) ne possède pas de vecteur connu, les trois autres espèces (genre Ampelovirus) sont transmises par cochenilles ...

A spot nested RT-PCR method for the simultaneous detection of members of the Vitivirus and Foveavirus genera in grapevine

Journal of Virological Methods, 2003
A reverse transcription (RT) polymerase chain reaction (PCR) assay was developed to allow rapid, and simultaneous detection of Vitivirus and Foveavirus sequences in two steps. The method involved a one-step RT-PCR, in which the combination of degenerate deoxyinosine-substituted primers amplified part of the polymerase region of both genera, followed by

Survey of mealybug (Hemiptera: Pseudococcidae) vectors of Ampelovirus and Vitivirus in vineyards of northwestern Italy

Phytoparasitica, 2010
Mealybugs (Hemiptera: Pseudococcidae) are sap-sucking insects which infest a broad range of crops worldwide. They represent an important threat to viticulture as they are vectors of viruses associated with leafroll and rugose wood complex diseases. In this study, we surveyed the presence of mealybugs and their associated viruses in vineyards of the ...
