松褐天牛Monochamus alternatus Hope是我国松林习见的重要蛀干害虫,也是松材线虫病的媒介昆虫。成虫羽化后,其气管携带大量线虫在成虫取食松树嫩皮时,线虫即经伤口进入树体。因此,成虫期不仅是天牛取食、扩散及生殖活动的重要时期,也是携带、传播松材线虫的关键虫态,是研究和防治松褐天牛及松材线虫病的重要环节。迅速而准确地判别松褐
Monochamus alternatus Hope Monochamus alternatus Hope pine borer is an important habit of pest weeds, but also pine wilt disease vector insects. Adult emergence, the trachea carrying a large number of nematodes in adult feeding pine nematode, the nematode that is through the wound into the tree. Therefore, the adult stage is not only an important period for the feeding, spreading and reproduction of the beetles, but also the key state of carrying and spreading the pine wood nematode. It is also an important part of the research and prevention and control of Monochamus alternatus and pine wilt disease. Quickly and accurately determine loose brown
