Tomato infectious chlorosis virus occurs in Sicilia, Italy
In Sicilia (Italy), prior to 2007 Tomato chlorosis virus (Crinivirus, ToCV – EPPO A2 List) was reported to occur in association with symptoms of interveinal leaf mottling and yellowing. Although Trialeurodes vaporariorum is widespread in Sicilia, Tomato infectious chlorosis virus (Crinivirus, TICV - EPPO A2 List) had not been detected at this time. In spring 2007, tomato samples, showing interveinal yellowing of older leaves, combined with thickening and brittleness, were collected in several glasshouses in the province of Ragusa and tested for the presence of criniviruses. Molecular tests (PCR, sequencing) confirmed the presence of both ToCV and TICV (in single or mixed infections). This is the first report of TICV in Sicilia.
