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。

On such a basis, it concretely discusses the effects of the cultivation on ecological environment and holds the view that the damage of the original hydro geological environment by over—cultivation in South—East China results in the serious situation of "no reservation of water and no irrigation when drought" and thus greatly increases difficulties in flood prevention. Local governments through ages act on their own way without cooperation among diked paddy—fields in different areas and therefore local floods take place every year due to breakdown of the dikes. The great shrinking of lake areas because of too much reclamation affects the function of lakes in adjusting water volume and destroys ecological condi- tions of the area, leads to frequent disasters.
