复叶槭挥发性物质对光肩星天牛的触角电位反应

该文供试的单体是用吸附法采集，并经热脱附及ＧＣ ＭＳ方法分离鉴定而得．作者分别测定了复叶槭１１ 种挥发性单体的５ 种浓度溶剂对光肩星天牛Ａｎｏｐｌｏｐｈｏｒａ ｇｌａｂｒｉｐｅｎｎｉｓ（ Ｍｏｔｓｃｈ ．） 的触角电位活性，以及不同触角部位的化学感受差异．测得各单体从高浓度到低浓度时的触角电位观测值均呈明显下降趋势．单体己醇、反 ２ 己烯醇、青叶醇、乙酸丁酯、己醛、青叶醛等在单独组分时有较强的触角电位活性，而单体青叶醛和乙酸丁酯、糠醛、甲基糠醛等相互混配时可增强光肩星天牛的触角电位活性．光肩星天牛成虫对挥发性物质刺激的敏感部位是触角的末端，乙醇对光肩星天牛的触角有一定的刺激作用．

Electroantennogram Activity of Ash-Leaf Maple (Acer negundo)Volatiles to Anoplophora glabripennis ( Motsch. )

The volatile components of ash\|leaf maple are extracted and determined by adsorption, thermo\|desorption and GC\|MS analysis. Electroantennogram (EAG)activity of 11 volatile chemical monomers in different concentration of ash\|leaf maple to Anoplophora glabripennis (Motsch.) antenna is determined. The influences of different parts of antenna and different solvents to A.glabripennis EAG are also studied. The results show that the EAG activity of different chemical monomers declined when their concentration decreased. As monomers, Hexanol, trans\|2\|Hexen\|1\|ol, Cis\|3\|Hexen\|1\|ol, Butyl acetate, Hexanal and trans\|2\|Hexen\|1\|al have strong EAG responses respectively. However, when trans\|2\|Hexen\|1\|al is mixed with Butyl acetate, Furfural and 5\|Methy\|Furfural, the EAG activities are obviously enhanced. It also concludes that the top antenna of A.glabripennis is the sensitive part to volatile, and ethanol may have some EAG responses to A.glabripennis .
