The flight response of both sexes of Dendroctonus brevicomis to the mixture of myrcene, racemic frontalin, and (1R,5S,7R)-(+)-exo-brevicomin and to the mixture of myrcene, (1S,5R)-(-)-frontalin and racemic exo-brevicomin was significantly greater than the response to the same mixtures in which the antipodes were substituted. The flight response to these two mixtures was also greater than the response to the ternary mixture of myrcene, racemic frontalin, and racemic exo-brevicomin (MFE). The walking response of both sexes to the mixture of myrcene, racemic frontalin, and (+)-exo-brevicomin was not different from the response to MFE. Substitution of the antipode lowered the response when compared to that of MFE. When evaporated with ponderosa pine turpentine, (-)-frontalin was active in the field while its antipode was not.
短角齿小蠹（Dendroctonus brevicomis）两性对月桂烯、外消旋长叶烯和（1R,5S,7R）-（+）-外-短叶松素混合物以及月桂烯、（1S,5R）-（-）-长叶烯和外消旋短叶松素混合物的飞行反应显著大于对其中对映体被替代的相同混合物的反应。对这两种混合物的飞行反应也大于对月桂烯、外消旋长叶烯和外消旋短叶松素三元混合物（MFE）的反应。两性对月桂烯、外消旋长叶烯和（+）-外-短叶松素混合物的行走反应与对MFE的反应没有差异。与MFE相比，对映体的替代降低了反应。当与黄松松节油一起蒸发时，（-）-长叶烯在野外具有活性，而其对映体则没有。
