The antennal responses of codling moth females, Cydia pomonella, to volatiles from apple branches with green fruits were recorded by electroantennography coupled to gas chromatography. The antennae strongly responded to 4,8-dimethyl-1,3(E),7-nonatriene, linalool, beta-caryophyllene, (E)-beta-farnesene, germacrene D, (Z,E)-alpha-farnesene, (E,E)-alpha-farnesene and methyl salicylate. These compounds were all present in volatile collections on Porapak Q from both living and cut branches. Analysis by the solid phase microextraction technique (SPME) showed that the emission of some electrophysiologically active compounds increased after branches had been cut, especially 4,8-dimethyl-1,3(E),7-nonatriene, linalool and (E,E)-alpha-farnesene. The identification of apple volatiles eliciting antennal responses is the first step towards the identification of compounds mediating host-finding and oviposition in codling moth females.
利用气相色谱联用触角电位技术记录了苹果蠹蛾（Cydia pomonella）雌蛾对带有绿色果实的苹果树枝挥发物的触角反应。触角对4,8-二甲基-1,3（E）,7-壬三烯、芳樟醇、β-石竹烯、（E）-β-法尼烯、杜松烯D、（Z,E）-α-法尼烯、（E,E）-α-法尼烯和水杨酸甲酯有强烈反应。这些化合物在来自活树枝和剪枝的Porapak Q挥发性提取物中均有存在。固相微萃取技术（SPME）分析表明，一些具有电生理活性的化合物在树枝被剪下后释放量增加，尤其是4,8-二甲基-1,3（E）,7-壬三烯、芳樟醇和（E,E）-α-法尼烯。鉴定引起触角反应的苹果挥发物是鉴定介导苹果蠹蛾雌蛾寻找寄主和产卵的化合物的第一步。
