摘 要：The stylet penetration behavior of aphids when feeding on plants is associated with virus acquisition and *** gifuensis (Ashmead)is a primary endoparasitoid of Myzuspersicae (Sulzer)which is the most efficient vector of plant viruses. Information about the effects ofparasitoid on aphid and virus transmission can provide an essential foundation for designing effective biological control *** study aimed to investigate the effects *** on the feeding behavior and potato virus Y (PVY) transmission ability of *** results showed that after *** was para-sitized by ***,the duration of the first probe significantly ***, *** exerted remarkable effects on aphid feeding in phloem *** contribution of the E1 waveform to the phloem phase was significantly higher in all parasitized aphids than in the control *** the time of infestation increased for parasitized aphids,the total duration of phloem sap ingestion ***,the percentage of time *** spent in the xylem and phloem phases only changed significantly on day *** percent transmission of PVY by the aphids parasitized on day 5 was lower than that in the control,but no significant differences were *** significance of this work is the demonstration that *** can impede the feeding behavior of ***,which sheds light on the biological basis *** as a natural enemy, but unfortunately does not provide an immediate solution for disrupting the transmission of PVY.
