Abstract:

The destiny of tomato yellow leaf curl viruses (TYLCVs), as well as other begomoviruses, ingested by Bemisia tabaci during feeding on infected plants is quite intriguing. During the first 12 to 48 h, the virus load reaches a threshold of approximately 600 million genomes per insect. This amount remains nearly stable, even though the insect continues to feed for days and weeks, raising several questions. How is such a limit maintained? What are the contributions of ingestion, egestion, excretion, replication, and immunity in maintaining this limit? How is the virus distributed along the circulative pathway and where is it stored? What are the constraints regulating the amount of virus in the insect vector, and what may happen to the insect (and/or the virus) if the regulation is impaired? This review presents and discusses the data implying that several different processes are involved in regulating the amount of begomovirus in B. tabaci, from the side of the insect as well as that of the virus, perhaps to prevent the virus to become pathogenic to its whitefly host.

What are the contributions of ingestion, egestion, excretion, replication, and immunity in maintaining this limit? How is the virus distributed along the circulative pathway and where is it stored? What are the constraints regulating the amount of virus in the insect vector, and what may happen to the insect (and/or the virus) if the regulation is impaired? This review presents and discusses the data implying that several different processes are involved in regulating the amount of begomovirus in B. tabaci, from the side of the insect as well as that of the virus, perhaps to prevent the virus to become pathogenic to its whitefly host.
