Abstract

For the type of virus transmission characteristic of leafhopper vectors, there is convincing evidence at the virus passes through the insect's body. The manner in which it emerges from the insect and comes to be inoculated into a plant is much is certainly known. It has generally been assumed that the saliva is the vehicle of the inoculation. For this assumption there is even now little dire t evidence.
