Technical Abstract: The majority of the defined plant viruses are transmitted by insects of the Hemipteroid assemblage that includes aphids, whiteflies, leafhoppers, planthoppers and thrips. In this review we highlight progress made in research on vector interactions of the more than 200 plant viruses that are transmitted in persistent circulative and propagative manners by hemipteroids. These plant viruses move through the insect vector, from the gut lumen into the hemolymph and finally into the salivary glands from which these viruses are introduced back into the plant during insect feeding. Insects often remain inoculative throughout their lifespan. The transtadial passage of different organs in the insect vectors requires specific interactions between virus and vector components. Recent investigations have resulted in a better understanding of the replication sites and tissue tropism of plant viruses in insect vectors. Furthermore, virus and insect proteins involved in this transtadial passage have been identified.
