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.
