In India, exploration of aphid species in vector-virus study was started during 1945 and subsequently, several aphid species have been identified as vectors of many important plant viruses. The studies in India was focused in identifying vectors, recording transmission efficiency, determining transmission parameters, recording distribution, and seasonal incidence and developing management options. A summary of these studies conducted in India so far is presented in this chapter.
