食线虫真菌防治家畜胃肠道线虫研究进展

摘要

In nature,nematophagous fungi present themselves as natural enemies of gastrointestinal nema-todes.They can be found in all kinds of environments in the world.At present,preliminary achievement has been achieved in the biological control of using nematophagous fungi against parasitic nematodes in ani-mals.In this peper,progress on nematophagous fungi for biological control of gastrointestinal nematodes in livestock was reviewed.In particular,in vitro tests and in vivo tests,and field trial were introduced in bio-logical control of gastrointestinal nematodes in domestic animals.So far,many studies have showed that Duddingtonia flagrans ,with passing through the gastrointestinal tract,is the most potential strain in bi-ological control of animal nematode diseases.It is proposed that for bio-control preparations,some key technologies of large scale production will be broken through to apply the bio-control techniques to live-stock production as early as possible in future.%在自然界，食线虫真菌本身作为动物胃肠线虫的天敌而存在，它们在世界各地各种各样的环境中被发现。目前，利用食线虫真菌对动物寄生线虫的生物防治已取得初步成果，论文介绍了食线虫真菌在家畜胃肠道线虫生物防治方面的研究进展，重点阐述了捕食线虫性真菌对家畜寄生线虫的体内外杀虫试验和田间试验的现状。诸多研究表明，鞭式达丁屯氏菌（Duddingtonia flagrans ）由于能通过动物的消化道，因而对控制家畜胃肠道线虫病最具应用潜力。建议今后在规模化生产生防制剂关键技术上取得突破，使其尽快用于畜牧业生产。
