Abstract: To explore the selectivity of the H.ligniperda to volatiles from Pinus thunbergii in different physiological states, the dynamic headspace adsorption was used to collect volatiles from healthy and harmed main trunks and roots of P. thunbergii in different damage degrees. The collected volatile samples were identified and analyzed by gas chromatography-mass spectrometry（GC-MS）, and the electrophysiological and behavioral responses of H. ligniperda to the main volatiles identified in this paper（or published paper） from P.thunbergii were analyzed by electroantennography（EAG） recording system and Y-type olfactory apparatus. The results showed that there were significant differences（P＜0.05） in the composition and content of volatiles in trunks and roots of P. thunbergii with different degrees of damage between healthy and different degree of damage. The relative content of the main compound（1R）-（+）-α-Pinene in the trunk decreased from healthy to wilted tree, and increased slightly in the wilted to dead standing tree stage. The relative content of（-）-β-Pinene increased significantly from the healthy stage to weakened tree, and gradually decreased in the weakened stage to dead standing tree. The relative content of（1R）-（+）-α-Pinene in the roots gradually decreased during the transition from healthy tree to dying tree stage, and its relative content increased in the dead standing tree. EAG test results showed that among those 10 tested volatiles, there were 9 substances triggered significant different EAG response values between female and male adults of H. ligniperda. Females had the highest response value to（1S）-（-）-α-Pinene at 0.1 mg/mL, and males had the highest response value to 0. 01 mg/mL Ocimene. The behavioral response results of Y-type olfactory apparatus showed that different concentrations of volatiles had different effects on male and femaleH. ligniperda. 0. 01-100 mg/mLα-Pinene, 100 mg/mLα-Terpinene, 10 mg/mL and 100 mg/mL（1S）-（-）-α-Pinene,（1R）-（+）-α-Pinene had a strong attractive effect on both male and female adultsH. ligniperda, and 10 mg/mL（-）-β-Pinene had a strong repellent effect on both male and female adultsH. ligniperda.Thus, 0.01-100 mg/mLα-Pinene, 100 mg/mL ofα-Terpinene, 10 mg/mL and 100 mg/mL of（1S）-（-）-α-Pinene,（1R）-（+）-α-Pinene could be used as an attractant component for male and female adultsH. ligniperda, and 10 mg/mL of（-）-β-Pinene could be used as an repellent component for adultsH. ligniperda.
