Abstract
Since the first reports from France and the Netherlands in 1980, whitefly-transmitted viruses have increased their irnpact on greenhouse and open-field crops in continental Europe. Arnong whitefly virus vector species , three are present in Europe: Bemisia tabaci (Gennadius), Parabemisia myricae (Kuwana) and Trialeurodes vaporariorum (Westwood). A number of clostero-like viruses, transmitted by T. vaporariorum, have been isolated in different European Countries and reported with different names. Viruses isolated in the Netherlands, France, Belgium, England and Italy have been almost immediately classified as beet pseudo-yellows virus (BPYV), but it is now recognized that also cucumber infectious chlorosis virus from Bulgaria, meion yellows virus from Spain, and a rnusiunelon yellows virus frorn France are closely related to BPW. Cucumber chlorotic spot virus from France might be a diferent virus. Tornato infectous chlorosis virus, another clostero-iike virus transmitted by T. vaporariurum, and distinct frorn BPW, has been recently isolated in Italy. A virus with clostero-like particles 790 nm long, vectored by B. tabaci and related to cucurbit yellow stunting disorder virus, has been isolated frorn rnelon in Spain. Among geminiviruses, tornato yellow leaf curl virus, vectored by B. tabaci, has been found in Italy, Spain and Cyprus. Tobacco leaf curi virus and abutilon rnosaic virus are present in vegetatively propagated maierial. Two more entities transmitted by whiteflies have been reported frorn Europe: maple mosic virus from Hungary, transmitted by T. vaporariorum, and, recently, citrus chlorotic dwarf, an infectious disease of citrus transmitted by P. myricae in Turkey.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
