相关的线虫Pristionchus pacificus和秀丽隐杆线虫都以细菌为食，因此当它们利用相同的细菌资源时，它们是竞争对手。除了相互竞争外，太平洋拟步行虫还是C.秀丽线虫幼虫的猎物。这两种关系共同形成了行会内的捕食，即杀死甚至吃掉潜在的竞争者。在杀死C。在线虫中，内团捕食者太平洋原教旨主义者可能会获得直接营养和减少对细菌的竞争的双重好处。最近的研究太平洋拟步行虫的捕食性叮咬行为以及潜在的分子和遗传机制的许多方面的特点。然而，很少有人探讨了潜在的竞争方面的太平洋拟步行虫咬C。优雅此外，如果太平洋拟步行虫故意叮咬C.目的是减少对细菌的竞争。本文综述了攻击性、捕食性和群体内捕食性之间的关系，以及这些概念在太平洋太平洋对虾与中国对虾相互作用研究中的应用。优雅
The related nematodes Pristionchus pacificus and Caenorhabditis elegans both eat bacteria for nutrition and are therefore competitors when they exploit the same bacterial resource. In addition to competing with each other, P. pacificus is a predator of C. elegans larval prey. These two relationships together form intraguild predation, which is the killing and sometimes eating of potential competitors. In killing C. elegans, the intraguild predator P. pacificus may achieve dual benefits of immediate nutrition and reduced competition for bacteria. Recent studies of P. pacificus 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 P. pacificus biting C. elegans. Moreover, aggression may also be implicated if P. pacificus intentionally bites C. elegans 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 P. pacificus in its interactions with C. elegans.
