描述了由 S. noctilio 注入茎边材的真菌 Amylostereum sp. 对辐射 P. radiata 的影响。这种真菌会导致边材在菌丝体形成之前就变干，并且进行了测试以确定它是否通过限制树液流向树冠或通过产生毒素来杀死树木。没有系统毒性作用可以归因于真菌，它似乎通过限制树液供应来发挥作用，但在实验性夜光夜蛾攻击后观察到迅速发展的系统效应，这意味着昆虫的分泌物与致病性有关。
Effects on P. radiata of the fungus, Amylostereum sp., which is injected into the sapwood of the stem by S. noctilio, are described. The fungus causes the sapwood to dry out in advance of the mycelium, and tests were made to find whether it kills the tree by restricting sap flow to the crown, or by producing toxins. No systemic toxic effects could be attributed to the fungus, which appeared to act by restricting sap supply, but rapidly developing systemic effects were observed after experimental S. noctilio attack, implying that a secretion of the insect was involved in pathoge~icity.
