Although whiteflies themselves can cause significant crop damage, whitefly-vectored viruses can cause losses that are much more economically damaging than those resulting from vector feeding alone. The majority of known whitefly-transmitted viruses are transmitted by Bemisia tabaci biotypes. The best known B. tabaci-transmitted viruses are those belonging to the genus, Begomovirus (Geminiviridae), which contains 90% of the whitefly-transmitted viruses characterized to date. Many of these viruses cause serious damage to variety of agricultural crops. Most are transmitted by the B biotype of B. tabaci (also referred to as B. argentifolii). In addition to the begomoviruses, B. tabaci transmits a limited number of viruses in the genera Carlavirus (Flexiviridae), Ipomovirus (Potyviridae) and Crinivirus (Closteroviridae). The only whitefly genus other than Bemisia identified as a virus vector is Trialeurodes. In contrast to the large number of viruses transmitted by Bemisia, only a handful of viruses have been found to be transmitted by Trialeurodes abutilonea and T. vaporariourum, all within the genus Crinivirus. The genus Crinivirus contains viruses transmitted by both bemisia and Trialeurodes. During the past thirty years, the importance of B. tabaci as a vector of plant viruses has continued to increase dramatically, to the extent that this once obscure whitefly is now among the most well known invasive insect and vector of plant viruses. Also, whitefly-transmitted viruses, which have been accidentally introduced to non-native locations, rapidly have established often causing more damage than the endemic viruses.
