This fungus is spread by Platypus quercivorus and easily infests the oak which grow relatively weak. Platypus quercivorus and oak fungus can be controlled by injuction of NCS into holes opened in oak.

由于该虫易侵入生长势相对较弱的栎类立木，通常危害木的树龄在 20 年以上，且以 40～50 年居多，通过钻孔注入适量的NCS等药剂后；用胶贴纸带包裹，可起到防治和杀灭栎长小蠹及&栎树菌&的目的。
