Plant-parasitic nematodes (PPNs) are significant pests that result in considerable economic losses in global crop production. Due to the high toxicity of chemical nematicides, there is a need to develop new strategies for nematode control. In this context, nematophagous fungi may offer a viable option for biological control. Two fungal strains (GUCC2212 and GUCC2232) were isolated from cysts of sp., identified as . The fungal filtrates of the strains were evaluated for their nematicidal activity against three species of PPNs: , and . The fermentation filtrates of two strains exhibited substantial toxicity towards the evaluated nematodes, with mortality rates reaching up to 100% within 72 h. Concurrently, also demonstrated predatory and parasitic behavior. The eggs of sp. were parasitized by the two strains. represents a newly recorded species in China and a novel nematophagous species. In conclusion, the two strains of show promise as biocontrol agents for PPNs management.
植物寄生线虫（PPNs）是重要害虫，在全球作物生产中造成巨大经济损失。由于化学杀线虫剂毒性高，需要开发新的线虫防治策略。在此背景下，食线虫真菌可能为生物防治提供可行选择。从孢囊线虫的孢囊中分离出两株真菌菌株（GUCC2212和GUCC2232），鉴定为[具体真菌种类]。评估了这些菌株的真菌滤液对三种植物寄生线虫的杀线虫活性：[线虫种类1]、[线虫种类2]和[线虫种类3]。两株菌株的发酵滤液对所评估的线虫表现出显著毒性，72小时内死亡率高达100%。同时，[真菌名称]还表现出捕食和寄生行为。孢囊线虫的卵被这两株菌株寄生。[真菌名称]是中国新记录种和新型食线虫物种。总之，这两株[真菌名称]菌株有望作为植物寄生线虫管理的生物防治剂。
