挥发物

Obducta to nine kinds of larch volatile compositions, namely R-α-pinene, S-α-pinene,β-pinene, ocimene, phellandrene, 3-carene, myrcene, camphene and phytol with EAG and Y-tube olfactometer. The results showed that 0.4 molL^(-1), most volatile compositions had significant EAG responses compared with the blank control (P.05), with exception of females to R-α-pinene, males to R-α-pinene and phellandrene.

结果表明：在0.4molL^(-1)浓度下，雌蛾除了对R-α-蒎烯、雄蛾除了对R-α-蒎烯和水芹烯没有明显EAG反应外，对其余挥发物的EAG反应与对照相比差异均达到显著水平(P.05)，并且雌、雄虫之间的EAG反应也存在一定的差异。

In this paper,the behavioral,physiological, ecological adaption mechanism of H.armigera and H.assulta to their common host plant tobacco were studied comparatively,and the main results were summarized as follows:Electroantennogram response of adult to tobacco volatiles:(1) H.armigera and H.assulta elicited similar EAG responses to the tested 20 tobacco volatiles;both of them elicited significantly more sensitive to green leaf volatiles,aliphatic and aromatic compounds, than to monoterpene,sesquiterpene,heterocyclic compounds under lower concentration; while the similar EAG responses under higher concentration were detected,but most of them were not significantly different with each other.

本文从行为、生理和生态适应三个方面，对棉铃虫和烟夜蛾与烟草间的互作进行了比较研究，主要结果如下：成虫对烟草挥发物的EAG反应：(1)两种夜蛾对测试的20种烟草挥发物均可产生EAG反应；低浓度下对绿叶气味、脂肪族、芳香族化合物的EAG反应显著高于单萜类、倍半萜类和杂环化合物；高浓度下的EAG反应也表现出相似的总体反应趋势，但多数反应值间的差异未达显著水平。
