Abstract：In order to find a method to control the damage of mangrove caused by the infestation of Sphaeroma,the volatile components of Sphaeroma were analyzed using headspace solid-phase microex-traction technology in combination with gas chromatography-mass spectrometry.The behavioral re-sponses of 5 main volatiles and 12 essential oils to Sphaeroma were measured using a self-made Y-shaped olfactometer.The results showed that there were 50 kinds of volatile components of Sphaeroma as were detected in GC-MS analysis,and the main components were hexadecane,nonadecane,benzal-dehyde,undecanal,8-heptadecene,octanal among others.We found that hexadecane,octanal and nut-meg essential oil have significant attraction on Sphaeroma;and the essential oils of Acorus gramineus and cinnamon essential oil have significant repellent effects on Sphaeroma.These findings should aid to selecting natural pesticides with citation and avoidance effects to prevent and control Sphaeroma infes-tation and protect mangroves.
