Begomoviruses are an emerging group of plant viruses, exclusively transmitted by the whitefly Bemisia tabaci in a persistent-circulative manner. Despite the economic importance of both, very little is known about begomovirus-whitefly interactions. Specific topics of interest that have been a subject of intensive research during the last decade include the route of the virus in the insect organs and cells, the influence of the virus on the insect’s behavior and transcriptome, the proteins that mediate begomovirus translocation and the role of bacterial symbionts in this phenomenon. These topics are summarized and discussed in this chapter. © Springer International Publishing Switzerland 2016.
