English. The Criniviruses ToCV and TICV were detected for the first time in protected crops of tomato in Campania and Calabria regions respectively. Specific molecular diagnosis for the two viruses allowed to find cases of mixed infections in Campania and infections caused exclusively by TICV in Calabria. Infestations of Trialeurodes vaporariorum and of Q biotype of Bemisia tabaci were found associated to the infections in Campania, while in Calabria only T. vaporariorum was identified. The two viruses induce in tomato the same symptomatology, often confused with the one caused by nutritional deficiencies. It is necessary to apply specific methods of molecular diagnosis in order to distinguish the two viruses, since no specific antisera are commercially available at the moment. This report represents a further evidence of the fast spread of TICV and ToCV in new areas of tomato cultivation

Italian. I Crinivirus ToCV e TICV vengono segnalati per la prima volta rispettivamente in Campania e Calabria in coltivazioni protette di pomodoro. Diagnosi molecolari specifiche per i due virus hanno consentito di rilevare casi di infezioni miste in Campania associate a infestazioni di Trialeurodes vaporariorum e di Bemisia tabaci biotipo Q e infezioni esclusivamente da TICV in Calabria associate a T. vaporariorum. I due virus determinano su pomodoro la stessa sintomatologia, spesso confusa con quella causata da carenze nutrizionali. E' necessario ricorrere a sistemi di diagnosi molecolare per distinguere i due virus, dal momento che non sono ancora disponibili antisieri commerciali specifici. Questa nota rappresenta un'ulteriore conferma della diffusione di TICV e ToCV verso nuovi areali di coltivazione del pomodoro
