Abstract: The electroantennogram (EAG) responses of alate and apterous adult aphids of Sitobion avenae and Rhopalosiphum padi to wheat plant volatiles and volatiles induced by aphid feeding were analysed. Variation of olfactory responses was also analysed. EAG responses of S.avenae to methyl salicylate, E-2-hexenal, E-2-hexenol,-6-methyl-5-hepten-2-one,-6-methyl-5-hepten-2-ol, and R. padi to methyl salicylate, E-3-hexenylacetate,-6-methyl-5-epten-2-one,-6-methyl-5-hepten-2-ol were stronger. The EAG responses to-6-methyl-5-hepten-2-one, E-2-hexenol and methyl salicylate were significantly different between alate and apterous adult aphids of S. avenae.EAG reponses to E-2-hexenol, octanal, linalol, methyl salicylate, E-3-hexenylacetate were also different between alate and apterous adult aphids of R. padi.

Key words: Sitobion avenae, Rhopalosiphum padi, wheat plant v olatiles, electroantennogram
