The citrus stubborn disease organism, Spiroplasma citri, has been transmitted from citrus to periwinkle plants by a leafhopper, Scaphytopius nitridus, which breeds on citrus in southern California. This is the first report of transmission of the stubborn disease organism by in-sects that acquired the organism by feeding on diseased citrus plants.
