The viral diseases transmitted by the whitefly Bemisia  tabaci (Hemiptera: Aleyrodidae) in tomatoes (Solanum lycopersicum) severely limit production in warm regions worldwide, including Spain. Since the late 1980s, viruses associated with tomato yellow leaf curl disease (TYLCD) have been an ongoing emergency and infections are systematic in the main tomato-growing regions of Spain. This disease is caused by various DNA viruses of the genus Begomovirus (family Geminiviridae) including Tomato yellow leaf curl virus (TYLCV), although other variants also circulate in epidemics and require effective control. The yellowing caused by RNA viruses such as Tomato chlorosis virus (ToCV, genus Crinivirus, family Closteroviridae) also causes significant crop losses and is an emerging problem. In addition, there are new threats such as possible infections from a new Begomovirus - Tomato leaf curl New Delhi virus (ToLCNDV), which is severely damaging cucurbits, especially courgettes (Cucurbita pepo). As the presence of this new virus has already been described in tomatoes, the risk of epidemics and damage may be merely a matter of time. Data will be given on possible cultural control alternatives and on the advantages of using genetic resistance in tomatoes, both to the virus and the insect vector.
