Electroantennograms (EAGs) were recorded fromD. ponderosae to the enantiomers of the terpenoid bark-beetle pheromonestrans-verbenol,cis-verbenol, verbenone, and the bicyclic ketals frontalin,exo-brevicomin, andendo-brevicomin. Male and female responses to enantiomers of the terpenoids differed significantly only at the two highest concentrations. No sex differences were seen in response to the bicyclic ketals. Significantly different responses to the enantiomers of all the chemicals, except frontalin, were noted over at least part of the dosage-response ranges tested. The negative antipode for all of the terpenoids elicited higher responses, while for the bicyclic ketals, the positive antipode effected the largest responses except for the two highest concentrations ofexo-brevicomin.
电触角图（EAGs）记录了来自 D. ponderosae 对萜烯类树皮甲虫信息素反式马鞭草烯醇、顺式马鞭草烯醇、马鞭草酮和双环酮前体、外-短棉素、内-短棉素的对映体。雌雄对萜烯类对映体的反应仅在两个最高浓度时有显著差异。双环酮对性别差异没有反应。除了前体，所有化学物质的对映体的反应都有显著差异，至少在部分测试剂量反应范围内都是如此。所有萜烯类的负对映体都引起了更高的反应，而对于双环酮，除了外-短棉素的两个最高浓度外，正对映体引起了最大的反应。
