Grapevine is not susceptible to tomato spotted wilt tospovirus

Experiments were carried out in Ontario, Canada, to test if grapevine cultivars are susceptible to tomato spotted wilt tospovirus (potential EPPO A2 quarantine pest). Eight Vitis vinifera cultivars, 34 Vitis hybrids, 7 V. labrusca cultivars and 3 V. rupestris cultivars were exposed to viruliferous Frankliniella occidentalis (EPPO A2 quarantine pest) and after one year additionally inoculated with the virus. The foliage of the plants was assayed by ELISA and bioassayed on Petunia X hybrida, but no infection of tomato spotted wilt virus occurred on grapevine. Feeding and reproduction of F. occidentalis occurred on the foliage of over 90% of the cultivars tested.
