The role of lignin as a physical defence against Dendroctonus micans was investigated in laboratory feeding experiments. The effect of lignin is dose-dependent, reducing larval survival, growth rate, and weight, as well as affecting gallery construction. Adults lay fewer eggs in lignified bark and also tend to construct abnormal galleries. The distribution of lignin in trees suggests a role in defence against bark beetles that feed in the thicker bark on the lower bole.
在实验室饲养实验中研究了木质素作为对云杉大小蠹物理防御的作用。木质素的作用具有剂量依赖性，会降低幼虫的存活率、生长速率和体重，还会影响蛀道构建。成虫在木质化树皮中产卵较少，并且往往构建异常蛀道。树木中木质素的分布表明其在防御以树干下部较厚树皮为食的小蠹虫方面发挥作用。
