Recent studies in California and Europe have shown that certain leafhoppers can transmit the stubborn disease organism, Spiroplasma citri, after acquiring it by various artificial means. We also know that one leafhopper, Scaphytopius nitridus (DeLong), can acquire the organism by feeding on infected citrus and can then transmit it to periwinkle plants (California Agriculture, January 1975) and citrus.
