摘　　要：作物病原线虫在我国危害严重,尤其是根结线虫和孢囊线虫经常流行成灾,严重威胁我国粮、经作物安全。建立作物病原线虫有效防控体系是保障我国农业可持续发展的重大战略需求。现有微生物杀线虫剂毒力有限、防效不稳、抗线虫资源匮乏是建立作物病原线虫有效防控体系面临的主要难题。提高现有微生物杀线虫剂的防效,寻找新的杀线虫资源,为有效控制病原线虫提供有效防控策略成为亟待解决的问题。通过作物、线虫、微生物三者间相互作用机制的了解,综述了作物线虫生物防控的研究进展,探讨作物线虫生物防控的发展前景。Plant-parasitic nematodes, including root-knot nematodes and cyst nematodes, are among the most notoriously difficult crop and wood pests to control. They not only cause directly serious crop losses, but also threaten our national agriculture, forestry, and food safety. Thus, effective control systems for plant-parasitic nematodes are required to maintain our national agricultural sustainable development. However, only a small repertoire of agents including microbial and chemical nematicides is available. Moreover, the available microbial nematicides have limited virulence and are unstable, and there is increasing nematode resistance to chemical nematicides. Therefore, improving the control effects of microbial nematicides and finding new sources of nematicides and application strategies have attracted much interest. Through comprehensive understanding of the interactions among the plants, nematodes, and microorganisms, the advances in research and future developements on the biocontrol of plant-parasitic nematodes were discussed in this paper.
