According to field surveys between 1998 and 2009, four tomatoinfecting begomovirus species detected in Taiwan were Ageratum yellow vein Hualien virus (AYVHuV), Tomato leaf curl Taiwan virus (ToLCTWV), Tomato yellow leaf curl Thailand virus (TYLCTHV), and Tomato leaf curl Hsinchu virus (ToLCHsV). After TYLCTHV first detected in 2005, it quickly replaced ToLCTWV in the tomato fields in Taiwan. In 2009, 8% of the positive samples were infected with ToLCTWV, 51% with TYLCTHV and 41% with mixed infection of both viruses. We performed field surveys again in 2015, 2016, and 2018, and we discovered that all symptomatic tomato plants were infected with ToLCTWV and/or TYLCTHV. Altogether, 59% of the positive samples were infected with ToLCTWV, 33% with TYLCTHV and 8% with mixed infection of both viruses. Surprisingly, the positive samples were more infected with ToLCTWV and less infected with TYLCTHV. To confirm the “revenge” of ToLCTWV in tomato fields, we plan to carry out a more extensive field survey in the upcoming year.
