The most damaging and economically important diseases of crops, especially in tropical and subtropical regions are caused by white fly transmitted begomoviruses. Begomoviruses are an extremely successful group of emerging plant viruses causing devastating diseases in vegetable, root, and fiber crops worldwide. Begomoviruses are transmitted in nature by Bemisia tabaci sensu lato, a complex of more than 40 morphologically indistinguishable whitefly species. These viruses are included in the genus Begomovirus of the family Geminiviridae and are responsible for causing crop losses ranging from 30% to 100%. During the 1950s, begomoviruses were reported to cause important losses in vegetables ranging from 20 to 100%. Begomoviruses are single-stranded circular DNA viruses, that replicate in the nucleus of their host cells and are classified as monopartite or bipartite viruses depending on their genome organization.
They have emerged everywhere in the world where environmental conditions support large whitefly (Bemisia tabaci Genn.) populations and in Western Africa, the emergence of begomoviruses is caused by genetically distinct species that have evolved locally.
