Feeding behavior characteristics of D. citri in the citrus phloem of healthy, CTV-infected, CLas-infected, and coinfected plants. a Time required to initial salivation by D. citri on different plants; b The total frequncies and durations of E1 waveform generation during D. citri feeding on plants infected with different pathogens; c The time of passive phloem ingestion by D. citri on different plants; d The total frequncies and durations of E2 waveform generation during D. citri feeding on plants infected with different pathogens. Different letters indicate significant differences at the 0.05 level according to the DMRT analysis
