[Research advances on resource and biological control of endoparasitic fungi.]

Endoparasitic fungi are a group of nematophagous fungi which produce a variety of special spores to infect free nematodes. They play a key role in maintaining the population density of nematodes in the natural systems. Moreover, they are important materials for the study of species diversity. Therefore, they have special research significance and economic values. At present, many studies mainly focus on the infectivity of trapping fungi to nematodes, and mainly directed at the second instars larvae. However, the endoparasitic fungi have infectivity to nematodes at all stages. Here, we reviewed the resource status, diversity of spore morphology, infection modes, life history and host of endoparasitic fungi, and the biocontrol fungi with development potential and their commercialized application. Finally, we proposed some suggestions for future researches.线虫内寄生真菌是一类能通过产生各种特殊孢子寄生游离线虫的食线虫真菌,对维持自然界线虫种群及其数量起到了关键作用,是线虫的重要天敌,也是研究物种多样性的重要材料,因此具有特殊的研究意义和经济价值.目前许多学者主要研究捕食线虫真菌对线虫的侵染力.这种食线虫真菌的侵染力主要针对二龄幼虫,而线虫内寄生真菌对线虫的各个时期都有侵染力.本文综述了线虫内寄生真菌物种资源现状,孢子形态多样性、侵染方式多样性、生活史多样性和寄主多样性,以及具有生防潜力和已商品化的生防菌的生防应用,探讨了在物种资源的发掘、物种分类鉴定和生防制剂商品化存在的问题及其对策,并展望了研究前景.
