Background

Pine wilt disease, also known as pine wilt disease, is a devastating epidemic disease of pine, which is caused by pine nematode parasitizing in pine body and mainly harms pine plants. The devastating harm of the disease is as follows: the pathogenicity is strong, and the death speed of the host is high; spread quickly and are often out of the way; once it occurs, the treatment difficulty is great. The epidemic disease is discovered in Nanjing in 1982 in China, and now occurs in a large range in forest regions in China, which not only causes huge loss to national economy, but also destroys natural landscape and ecological environment, and poses serious threat to China's rich pine forest resources. The propagation path is mainly two: the method is characterized in that firstly, the transmission of medium insects such as monochamus alternatus hope is carried out in a short distance, and secondly, the transmission is carried out in a long distance by means of the allocation and transportation of infected nursery stocks, pine woods, branches and other pine products. Until now, the control of the pine wood nematode disease is still a worldwide technical problem, and the quarantine of the pine wood nematode disease is the key point of quarantine. Pine wood and pine wood products carrying pine wood nematodes found in quarantine are mainly treated in the following ways: fumigating or treating with methyl bromide; or soaking in water for more than 5 months; or sent to factories for processing and then used as industrial raw materials such as fiber boards, particle boards or paper pulp; small diameter wood, branches, needles and the like with low utilization value are burnt intensively. The method comprises the following steps: the chemical method has high treatment cost, long time for soaking treatment, easy environmental pollution and resource waste caused by burning treatment. In the existing prevention and control process of forest diseases such as the pine wilt disease, most pine which is infected with the disease and died is required to be removed and transported to a wood processing factory for processing or fragmentation, and the pine cannot be processed on site, so that the defects of infected tree loss, vector insect spread and the like are easily caused, and the spread of the disease are caused.
