This Quick scan was prompted by an EPPO report on an emerging virus disease in Cucurbitaceae in Asia caused by Melon yellow spot virus. The virus is vectored by Thrips palmi which is absent from the Netherlands and the rest of the EU. Thrips palmi is regulated in the EU and measures should be taken to prevent its introduction (Council directive 2000/29/EC). Without its vector, the virus can probably not establish in the Netherlands.
