摘要: The Panel on Plant Health performed for the European Union (EU) territory a pest categorisation of Tomato yellow leaf curl virus (TYLCV) and three related viruses, Sardinia (TYLCSV), Axarquia (TYLCAxV) Malaga (TYLCMaV), which collectively cause tomato disease (TYLCD) in Europe. viruses are well-defined species genus Begomovirus, exclusively transmitted by members Bemisia tabaci complex have tomato, as well few other crops or weeds, their hosts. TYLCV is listed plants planting, than seeds, Annex IIAII Directive 2000/29/EC. While establishment local spread rely vector, can also be disseminated over long distances movement infected planting consignments non-host carrying viruliferous whiteflies. Establishment outdoors limited to regions with ecoclimatic conditions suitable vector populations open. Outbreaks nevertheless occur under protected cultivation conditions. Because very high potential impact TYLCD, production affected requires intensive crop management efforts reduce impact. appears present almost all EU its open fields, while do not appear reached full potential. All four absent from but temporary outbreaks there. © Food Safety Authority, 2014
