Electroantennogram Responses of Atrijuglans hetaohei to Plant Volatiles
摘要
Abstract
The moth Atrijuglans hetaohei is a major pest to walnut fruit.It is useful to screen out the effective compounds of plant volatiles for developing an alternative method for monitoring and controlling A.hetaohei.By using electroantennogram (EAG) instrument,this study examined the EAG responses of A.hetaohei adults to 38 kinds of plant volatiles.The results indicated that A.hetaohei showed stronger EAG responses to aliphatics,followed by aromatics and monoterpene hydrocarbons.Females were more sensitive to most plant volatiles,such as hexyl acetate and (E)-2-hexenyl acetate.Meanwhile,males were more sensitive to (E)-2-hexenol,(E)-2-hexenal.In aromatic compounds,the relative EAG values of 245.86％ and 190.77％ revealed that significant EGA reactions of male and female could be induced by benzene formaldehyde.Among monoterpene hydrocarbons,while females were more sensitive to geraniol and linalyl acetate,males were more sensitive to citral.Dosage response curves of EAG of A.hetaohei showed that the trends of reactions of females and males were the same to (E)-2-hexenol,(E)-2-hexenal,(Z)-3-hexenyl acetate,(Z)-3-hexenol,hexyl acetate,ethyl caproate and benzene formaldehyde.However,the trends of their reactions to (E)-2-hexenyl acetate,geraniol and linalyl acetate showed differences.Sensitivity differences between both sexes to plant volatiles suggested that ecological adaptation of this species and the females were more sensitive to most plant volatiles,which would be useful for their finding of hosts.The results would provide a reference for developing attractive chemicals for A.hetaohei in the fields.关键词
