The insect innateimmunesystem is assorted into two general categories, cellular and humoral immunity. Aside from direct challenge by invaders, predation risk can be perceived as odors, sounds or nearness. In this study, we evaluated influence of predation risk by the predatory bug Podisus maculiventris on immunity of an herbivore Spodoptera frugiperda. Under the predator-induced stress combined with Escherichia coli inoculation, several larval physiological parameters of S. frugiperda were studied, including body mass, nodulation, and phenoloxidase activity. Our findings offernew evidence that provides insight into the immunological mechanism of predator-induced stress effects on prey species.
昆虫先天免疫系统分为细胞免疫和体液免疫两类。除了直接受到入侵物的挑战，捕食风险还可以通过气味、声音或接近程度来感知。在这项研究中，我们评估了捕食性昆虫美洲大蠊对草食性昆虫草地贪夜蛾免疫力的捕食风险影响。在受到捕食者诱导的压力和大肠杆菌接种的双重作用下，我们研究了草地贪夜蛾的几种幼虫生理参数，包括体重、结节和酚氧化酶活性。我们的研究结果提供了新的证据，深入了解了捕食者诱导的压力对猎物物种的免疫机制的影响。
