通过林间调查、根桩解剖、线虫分离等试验，结果表明，在伐桩、木质部内存在数量较少的松褐天牛越冬幼虫；该幼虫次年羽化成成虫，具有传播松材线虫病能力。通过对不同高度伐桩中天牛活体数量调查和农药处理伐桩试验，认为在伐桩高度低于５ｃｍ时，用２０％倍硫磷油剂＋０号柴油２０倍稀释液浇淋伐桩，具有既简单又彻底的杀灭伐桩内天牛和控制松材线虫病的良好效果。 Through forest investigation, root anatomy and nematode separation, the results showed that overwintering larvae of Pinus tabulaeformis were present in the felling and xylem. The larvae became adult in the following year and had the ability of transmitting pine wood nematode . Through the investigation of the number of live beetle and the pile cutting experiment of pesticide treatment in different height pile cutting, it is considered that when the height of pile cutting is less than 5cm, the pile is poured with 20% times thiophosphate oil + 20 times dilution of No. 0 diesel oil, with Both simple and thorough kill kill the celastris and control pine wilt disease good results.
