Abstract
Clover phyllody symptoms appeared on 34 species of plants in 13 families inoculated by infective Macrosteles fascifrons (Stål) or Aphrodes bicinctus (Schrank). Forty-five other species of plants in 12 families showed no infection although they were inoculated by insects shown to be infective by subsequent transmission to aster. M. fascifrons also transmitted CPV from 17 of 18 infected species tested. Characteristic symptoms on infected plants of some of the species are described and illustrated.Efficiency of transmission and the ability to survive on a wide range of plant species demonstrates the importance of M. fascifrons as a vector for host range studies.
