植物寄生线虫作为一类植物病原，对全球农林业产生严重危害，每年由植物寄生线虫造成的损失平均高达1 570亿美元。食线虫真菌作为一种安全、高效、低毒防治线虫的生物技术，已受到广泛关注。讨论了食线虫真菌的分类、对线虫的作用机制、防控效果的影响因素和应用现状，并在此基础上，对食线虫真菌与植物寄生线虫互作的研究前景进行了展望。

Plant parasitic nematodes,as a kind of plant pathogens,cause harm to global agriculture and forestry.The loss caused by plant parasitic nematodes was S157 billion per year. Nematode-trapping fungi have attracted wide attention as a safe,efficient and low-toxic biotechnology for the control of nematodes.In this paper,the classification,action mechanism,control effect,influencing factors and application status of nematode-trapping fungi were discussed,and the prospect of interaction between nematode-trapping fungi and plant parasitic nematodes was prospected.
