[Objectives]  To study the effect of mugwort Artemisia argyi volatiles on Empoasca onukii in order to identify compounds suitable for developing a “push-pull” strategy to control this pest in tea plantations. [Methods]  Mugwort volatiles were collected and identified with SPME-GC-MS and the behavioral responses of E. onukii to 10 of these compounds were then tested in a Y-tube olfactometer. Behaviorally-active compounds were also tested in a tea plantation. [Results]  Third instar nymphs had a significantl negative taxis response to A. argyi odors (P<0.01). Seventy-two volatile compounds were identified from A. argyi shoots with fresh leaves. Among these, β-caryophyllene, D-camphre, Germacrene D and 1S-alpha -Pinene were the most abundant, accounting for 27.81%, 10.94%, 7.19% and 4.23% of the total content, respectively. Compared to the control, β-pinene at concentrations of 1 µL/mL and 0.01 µL/mL，β-caryophyllene at the concentration of 1 µL /mL and cis-carveol at the concentration of 100 µL/mL, significantly repelled 3rd instar nymphs (P<0.01 or P<0.05), whereas piperitone, at the concentration of 1 µL/mL, significantly attracted these (P<0.05). Field experiments show that β-pinene, β-caryophyllene and cis-carvol repel adult green leafhoppers, thereby reducing the number captured on yellow board traps. [Conclusion]  Three bioactive compounds of A. argyi volatiles (β-pinene, β-caryophyllene and cis-carvol) are repellent to E. onukii and the degree of repellence increases with dosage.
