There exist the various herbaceous and woody plants in tea plantation ecosystem, among which the rosemary is a common woody plant species. Potential effect of volatiles from tender rosemary shoots with fresh leaves on the tea green leafhopper behavior was assayed using Y-tube olfactometer against the clear air as CK. The result showed that the numbers of the tea green leafhoppers to choose the rosemary odor source firstly increased as the increase of odor dosage, and then reduced as further increase of the odor dosage in a parabolic curve-like relationship. 46 volatile compounds were identified from the rosemary shoots with fresh leaves, including 9 alcohols, 4 ketones, 4 esters, 1 acid, 18 alkenes, 7 alkanes, 1 ether, 1 aldehyde and 1 phenol. Alcohol was the major volatile group with 52.20% of the total amount. Eucalyptol, 1s-α-pinene and verbenone were three major components, accounting for 42.54%, 10.37% and 6.82% of the total content, respectively. From the identified rosemary volatile compounds, 25 synthetic candidates representing all the major and some minor components were tested in Y-tube tube olfactometer in several dosages on the tea green leafhoppers against hexane as CK. 10^-2g/mL camphor, 10^-4g/mL caryophyllene, 10^-6g/mL and 10^-8g/mL α-phellandrene, 10^-4g/mL and 10^-10g/mL α-terpineol, 10^-10g/mL and 10^-8g/mL eucalyptol displayed a significant attraction to the leafhopper, whereas 10^-10g/mL β-pinene showed a significant repellency. Thus, it is possible that other plant species in the tea plantation community might be also attractive the tea green leafhoppers, which can be considered as candidate plant species for screening the effective trap plants.
