用顺式-11-十四烯乙酸酯、反式-11-十四烯乙酸酯和十二烷基乙酸酯（12：Ac）三种雌虫产生的性信息素组分的混合物，记录了红条卷叶蛾（Argyrotaenia velutinana）雄蛾触角的触角电生理反应。含有3%、8%和15%反式切割的二元混合物引起的振幅响应显著高于其他同分异构体混合物以及纯反式切割和反式切割。对这种混合物的较高响应低于高剂量下的加性和低剂量下的加性。使用这两种异构体的受体适应性研究支持先前的单单位研究，证明在maleA上存在至少两个功能不同的受体位点。velutinanaantennals;适应含有一种异构体的气流并不能消除对同时出现的相反异构体的反应。含有第三种成分12：Ac的气流在EAG对cisbut nottrans的反应的整个恢复期内引起恢复速率的显著减慢，这表明12：Ac对神经元反应的可能的时间调制可能是触角感觉神经元编码该成分的一种手段。
Electroantennogram (EAG) responses were recorded from male redbanded leafroller moth,Argyrotaenia velutinana, antennae using mixtures of the three female-produced sex pheromone components:cis-11-tetradecenyl acetate,trans-11-tetradecenyl acetate, and dodecyl acetate (12:Ac). Binary mixtures containing 3%, 8%, and 15%transinciselicited significantly higher amplitude responses than other isomeric mixtures as well as purecisandtransalone. The higher responses to such mixtures were less than additive at high dosages and additive at lower dosages. Receptor adaptation studies using the two isomers support a previous single unit study demonstrating the presence of at least two functionally different receptor sites on maleA. velutinanaantennae; adaptation to an airstream containing one isomer did not eliminate response to the opposite isomer presented concurrently. An airstream containing the third component, 12:Ac, caused a significant slowing of the recovery rate during the entire recovery period of EAG responses tocisbut nottrans, suggesting that a possible temporal modulation of neuronal response by 12:Ac may be a means of coding for this component by antennal sensory neurons.
