摘　　要：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。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.
