The related nematodes and both eat bacteria for nutrition and are therefore competitors when they exploit the same bacterial resource. In addition to competing with each other, is a predator of larval prey. These two relationships together form intraguild predation, which is the killing and sometimes eating of potential competitors. In killing , the intraguild predator may achieve dual benefits of immediate nutrition and reduced competition for bacteria. Recent studies of have characterized many aspects of its predatory biting behaviour as well as underlying molecular and genetic mechanisms. However, little has been explored regarding the potentially competitive aspect of biting . Moreover, aggression may also be implicated if intentionally bites with the goal of reducing competition for bacteria. The aim of this review is to broadly outline how aggression, predation, and intraguild predation relate to each other, as well as how these concepts may be applied to future studies of in its interactions with .
相关线虫和都以细菌为食，因此当它们利用相同的细菌资源时，它们是竞争者。除了相互竞争外，还是幼虫猎物的捕食者。这两种关系共同构成了种内捕食，即捕食潜在竞争者并有时吃掉它们。在捕食中，种内捕食者可能会获得即时营养和减少对细菌竞争的双重好处。最近对的捕食行为的研究已经描述了其捕食性咬伤行为的许多方面，以及潜在的分子和遗传机制。然而，关于咬伤的潜在竞争方面的研究还很少。此外，如果有意咬伤以减少对细菌的竞争，那么攻击行为也可能涉及其中。本综述的目的是广泛概述攻击、捕食和种内捕食之间的关系，以及这些概念如何应用于未来与相互作用的研究。
