Electroantennograms were recorded fromScolytus multistriatus in response to 4-methyl-3-heptanol, the four geometric isomers of multistriatin, and cubeb oil. Charateristic dose-response curves for response amplitude and the time required for the voltage trace to return to 1/2 baseline (recovery rate) were established. Recovery rates were significantly more rapid following stimulation with 4-methyl-3-heptanol or cubeb oil than with the multistriatin isomers. At most intensities, α-multistriatin, the isomer that evokes behavioral response, gave significantly larger EAGs with significantly longer recovery rates than the other isomers. Results of differential adaptation experiments suggested that 4-methyl-3-heptanol interacted with the processes involving multistriatin and cubeb oil activity. However, cross-activity of acceptors for these compounds seems unlikely; single sensillum recordings are needed to ascertain the response spectra for individual receptor neurons.
电触角图记录了多纹豹蠹甲对 4-甲基-3-庚醇、多纹豹蠹甲的四个几何异构体以及胡椒酮的反应。建立了响应幅度和电压迹线恢复到 1/2 基线所需时间（恢复率）的特征剂量反应曲线。与多纹豹蠹甲异构体相比，用 4-甲基-3-庚醇或胡椒酮刺激时，恢复率明显更快。在大多数强度下，引起行为反应的α-多纹豹蠹甲异构体比其他异构体产生的 EAG 更大，恢复率也更长。差异适应实验的结果表明，4-甲基-3-庚醇与涉及多纹豹蠹甲和胡椒酮活性的过程相互作用。然而，这些化合物的接受器的交叉活性似乎不太可能；需要单感器记录来确定单个受体神经元的反应光谱。
