疫情的特点是特定物种的种群密度突然增加，在自然和人工系统中都被认为是一种重要现象。气候和人为压力源是直接影响节肢动物种群的暴发的主要非生物驱动因素，或通过其异种性和资源（例如寄主植物）间接影响它们。两者都是剂量或强度依赖的，在考虑暴发时主要是亚致死的。因此，亚致死刺激或激效是需要考虑的重要现象。然而，其研究仅限于少数（农业）环境，忽视了生物系统的关键复杂性，包括节肢动物作为共生体的生态环境，节肢动物相互作用的作用以及多种应激源的共存。因此，需要更多的研究来解决生物系统的复杂性。
Outbreaks are characterized by a sudden increase in population density of a given species, and are recognized as an important phenomenon in both natural and artificial systems. Climate and anthropogenic stressors are the main abiotic drivers of outbreaks directly affecting arthropod populations, or influencing them indirectly through their heterospecifics and resources (e.g., host plants). Both are dose- or intensity-dependent and mainly sublethal when outbreaks are considered. Thus, sublethal stimulation or hormesis is an important phenomenon to consider. However, its study is restricted to a few (agricultural) settings and neglects key complexities of biological systems, including arthropods as an ecocosm of symbionts, the role of arthropod interactions, and the co-occurrence of multiple stressors. Therefore, more research is required to tackle the complexities of biological systems.
