Electroantennogram Responses of Female and Male Adults of Potosia brevitasis Lewis to Volatile Alcohols and Aldehydes
摘要
Abstract
The Potosia brevitasis Lewis belongs to the family cetoniidae of coleoptera.It is distributed throughout China,and has a wide host range.[Objective] To better understand differential responses of female and male adults of P.brevitasis to alcohols and aldehydes with different carbon chain-length and unsaturation.[Method] A total of 33 compounds were chosen for electrophysiological response test using electroantennography technique.[Result]The results showed that Hexanol,Heptanol,Octanol,Nonanol,(Z)-3-Hexenol,(Z)-2-Hexenol elicited significant EAG responses.At the same dose,the females always displayed stronger responses than males.Furthermore,the responses to primary,secondary,and tertiary alcohols decreased gradually.The saturated aldehydes with 6 to 9 carbon chain-length elicited significant EAG responses,among which,the 8 carbon aldehyde octanal the EAG reaction value was the largest.[Conclusion] The EAG responses of volatile alcohols and aldehydes in female adults was higher than in male adults.关键词
