Abstract
In an earlier paper (Storey 1933) I showed that, after Cicadulina mbila Naude had fed on a source of the maize streak virus, this virus appeared externally to the intestine in the insect's blood. The next stage, it may be supposed, is the collection of the virus at some centre whence it becomes available for ejection into a plant. It seems hardly possible to doubt that this centre is the salivary gland, and that the saliva is the vehicle whereby the virus is transferred into the plant. Nevertheless, my attempts to demonstrate a virus in the saliva have met with almost uniform failure.
