Chrysanthemum yellows phytoplasma (CYP) transmission efficiencies of Macrosteles quadripunctulatus and Euscelidius variegatus following artificial feeding in the presence and absence of proteins and successive acquisition on CYP-infected plant. Transmission efficiency: percentage of CYP PCR positive plants following inoculation with all insects surviving the latent period. Within columns, figures followed by different letters differ significantly (Chi square test). Sample sizes in parenthesis
