A comprehensive review: persistence, circulative transmission of begomovirus by whitefly vectors.

Plant pathogenic viruses rely on insect vectors for transmission. Among insects, hemipterans, including aphids, leafhoppers, plant hoppers, whiteflies, mealybugs, true bugs, and certain treehoppers, are predominant as vectors for plant viruses. Plant viruses contribute to more than 47% of worldwide plant diseases. Bemisia tabaci is one of the most threatening pests in agriculture, causing significant losses to many important crops on a global scale. Among the most destructive viruses facilitated by whiteflies are begomoviruses (Geminiviridae), forming an emergent and critical group of plant pathogens solely transmitted by the sweet-potato whitefly Bemisia tabaci. In this comprehensive review, we delve into the wealth of data concerning the diverse transmission capacities of various whitefly species, including cryptic members of the B. tabaci complex, in their role as vectors for begomovirus and other viruses. We presented a meticulous analysis of the factors influencing viral transmission by whiteflies, shedding light on the intricate interplay of viruse and their insect vectors. Moreover, this review serves as a crucial reference, presenting a profound exploration of the intricate relationships between whitefly vectors and begomoviruses, and providing valuable insights for the scientific community working towards the sustainable management of plant diseases in the face of evolving challenges posed by these complex biological systems.
