Nematode-trapping fungi develop complex trapping devices to capture and consume nematodes. The dynamics of these organisms is especially important given the pathogenicity of nematodes and, consequently, the potential application of nematode-trapping fungi as biocontrol agents. Furthermore, both the nematodes and nematode-trapping fungi can be easily grown in laboratories, making them a unique manipulatable predator-prey system to study their coevolution. Several different aspects of these fungi have been studied, such as their genetics and the different factors triggering trap formation. In this review, we use the nematode-trapping fungus Arthrobotrys oligospora (which forms adhesive nets) as a model to describe the trapping process. We divide this process into several stages; namely attraction, recognition, trap formation, adhesion, penetration, and digestion. We summarize the latest findings in the field and current knowledge on the interactions between nematodes and nematode-trapping fungi, representing both sides of the predator-prey interaction.
线虫诱捕真菌会发展出复杂的诱捕装置来捕获和消耗线虫。鉴于线虫的致病性，这些生物的动态变化尤其重要，因此线虫诱捕真菌作为生物防治剂具有潜在的应用价值。此外，线虫和线虫诱捕真菌都可以很容易地在实验室中培养，这使得它们成为一个独特的可操纵的捕食者-猎物系统，可以用来研究它们的共同进化。已经研究了这些真菌的几个不同方面，例如它们的遗传学和触发陷阱形成的不同因素。在这篇综述中，我们使用线虫诱捕真菌 Arthrobotrys oligospora（形成粘性网）作为模型来描述诱捕过程。我们将这个过程分为几个阶段：即吸引、识别、陷阱形成、黏附、穿透和消化。我们总结了该领域的最新发现和线虫与线虫诱捕真菌之间相互作用的现有知识，代表了捕食者-猎物相互作用的两个方面。
