Tomato yellow leaf curl virus (TYLCV, genus Begomovirus, family Geminiviradae), vectored by the whitefly Bemisia tabaci, is one of the tomato infecting viruses which is inducing the most obvious symptoms. The severe growth reduction of the plants and the typical yellowing and curling of the leaves due to TYLCV infection is easily detected by farmers, even not being familiar with those symptoms. Therefore, it is expected that the introduction of TYLCV in a new environment is detected soon after the first infection of tomato plants. This was the case in 1997, when TYLCV was detected for the first time in Reunion, an island of the Indian Ocean at about 700 km east of Madagascar (Peterschmitt et al., 1999). One more reason for which it is thought that the delay between introduction and detection was short is that the local Plant Protection Services were aware of the TYLCV risk.
Subsequently to the first detection of TYLCV, the sampling of infected tomato plants and the collection of B. tabaci vectors over time gave us a unique opportunity to monitor the emergence and installation of a virus and its vector in an insular environment.
