采用活体植物动态顶空套袋法与气质联用分析技术，对楝（Melia azedarach）的挥发性化学物质进行分析，并且利用GC-EAD技术测定了星天牛（Anoplophora chinensis）成虫对楝挥发性化学物质的GC-EAD反应，结果表明：楝的挥发性化学物质有20种，其中含有萜烯类化合物（97.71%）8种，烃类化合物（1.021%）5种，醇类化合物（0.23%）3种，酮类化合物（0.02%）1种；星天牛成虫的触角对5种化合物的刺激作用比较敏感，其中对β-蒎烯刺激活性最高，对左旋-α-蒎烯、月桂烯、丁苯、桃金娘烯醇有较轻微的反应。
採用活體植物動態頂空套袋法與氣質聯用分析技術，對楝（Melia azedarach）的揮髮性化學物質進行分析，併且利用GC-EAD技術測定瞭星天牛（Anoplophora chinensis）成蟲對楝揮髮性化學物質的GC-EAD反應，結果錶明：楝的揮髮性化學物質有20種，其中含有萜烯類化閤物（97.71%）8種，烴類化閤物（1.021%）5種，醇類化閤物（0.23%）3種，酮類化閤物（0.02%）1種；星天牛成蟲的觸角對5種化閤物的刺激作用比較敏感，其中對β-蒎烯刺激活性最高，對左鏇-α-蒎烯、月桂烯、丁苯、桃金孃烯醇有較輕微的反應。

Voltile organic compounds/VOCs fromMelia azedarach were collected by dynamic headspace and determined by TDS/ GC/MS. Response ofAnoplophora chinensis to VOCs was detected by GC-EAD. The result demonstrated that there were 20 types of VOCs fromM. azedarach, including 8 terpenoids(97.71%), 5 aromatics(1.021%), 3 alcohols(0.23%), 1 ketones(0.02%). GC-EAD detection showed that that the antenna ofA. chinensis were sensitive to five compounds. Beta-pinene had the most effective to the insect, and L-alpha-pinene, myrcene, styrene butadiene and myrtenol had litter effect.
