Begomoviruses contain some of the most damaging viral disease agents of crops worldwide, and are transmitted by whiteflies of the Bemisia tabaci species complex. During the last 20 years, transovarial transmission of tomato yellow leaf curl virus (TYLCV) has been reported in two invasive species of the B. tabaci complex. To further decipher the importance of this mode of transmission, we analyzed transovarial transmission of TYLCV by seven whitefly species indigenous to China. TYLCV virions were detected in eggs of all species except one, and in nymphs of two species, but in none of the ensuing adults of all seven species. Our results suggest that these indigenous whiteflies are unable to transmit TYLCV, a begomovirus alien to China, via ova to produce future generations of viruliferous adults, although most of the species exhibit varying ability to carry over the virus to the eggs/nymphs of their offspring via transovarial transmission.

A genus of plant viruses in the family SEQUIVIRIDAE. Transmission is by APHIDS but depends on the presence of a helper protein encoded by the Anthriscus yellow virus, a WAIKAVIRUS. The type species is Parsnip yellow fleck virus (parsnip serotype).
A genus of plant viruses in the family BUNYAVIRIDAE. Tomato spotted wilt virus is the type species. Transmission occurs by at least nine species of thrips.
A genus of plant viruses that infects ANGIOSPERMS. Transmission occurs mechanically and through soil, with one species transmitted via a fungal vector. The type species is Tomato bushy stunt virus.
A genus of DNA plant viruses with bacilliform morphology. Transmission in clonally-propagated plants is by vegetative propagation of infected plant materials. Transmission in nature is by mealybugs, seeds, and pollen. The type species is Commelina yellow mottle virus.
The type species of the FLAVIVIRUS genus. Principal vector transmission to humans is by AEDES spp. mosquitoes.
