Abstract
Only five minutes are required by the melon aphid—Aphis gossypii Glover— after feeding on a diseased citrus tree, to transmit the tristeza—quick decline— virus to a healthy tree. However, the aphid does not remain infective long— probably most individuals lose their ability to transmit the virus shortly after leaving the diseased tree—and apparently only an occasional individual aphid is able to transmit the virus at all.
