Stridulation by male Dendroctonus pseudotsugae was recorded in response to the natural female attractant (frass) or to three synthetic components of the attractant (frontalin, 3-methyl-2-cyclohexen-1-one, and trans-verbenol). This stridulation was acoustically distinct from stress sound and correlated with known attraction behavior. The response of female D. pseudotsugae to male stridulation-negation her attraction-was induced by playback of recorded attractant stridulation but not by that of stress sounds. Acoustic communication must be more important in scolytid behavior than it was heretofore believed to be.
雄性齿小蠹通过摩擦发声来回应天然的雌性引诱物（粪便）或三种引诱物的合成成分（法呢醇、3-甲基-2-环己烯-1-酮和反式马鞭草烯醇）。这种摩擦发声与应激声在声学上是不同的，与已知的吸引行为相关。雌性齿小蠹对雄性摩擦发声的反应（否定了雄性的吸引力）是由记录的引诱物摩擦发声的回放引起的，但不是由应激声的回放引起的。声音通讯在小蠹行为中的重要性比以前认为的要大。
