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