Agricultural insect pests display an exceptional ability to adapt quickly to natural and anthropogenic stressors. Emerging evidence suggests that frequent and varied sources of stress play an important role in driving protective physiological responses; therefore, intensively managed agroecosystems combined with climatic shifts might be an ideal crucible for stress adaptation. Cross-protection, where responses to one stressor offers protection against another type of stressor, has been well documented in many insect species, yet the molecular and epigenetic underpinnings that drive overlapping protective responses in insect pests remain unclear. In this perspective, we discuss cross-protection mechanisms and provide an argument for its potential role in increasing tolerance to a wide range of natural and anthropogenic stressors in agricultural insect pests. By drawing from existing literature on single and multiple stressor studies, we outline the processes that facilitate cross-protective interactions, including epigenetic modifications, which are understudied in insect stress responses. Finally, we discuss the implications of cross-protection for insect pest management, focusing on the consequences of cross-protection between insecticides and elevated temperatures associated with climate change. Given the multiple ways that insect pests are intensively managed in agroecosystems, we suggest that examining the role of multiple stressors can be important in understanding the wide adaptability of agricultural insect pests. © 2022 The Authors.

害虫的交叉保护相互作用：气候变化对害虫管理的影响

农业害虫显示出快速适应自然和人为压力源的非凡能力。新出现的证据表明，频繁和多样的压力来源在驱动保护性生理反应方面发挥着重要作用；因此，集约化管理的农业生态系统与气候变化相结合可能是压力适应的理想熔炉。交叉保护，即对一种应激源的反应提供了针对另一种类型的应激源的保护，在许多昆虫物种中都有很好的记录，但在害虫中驱动重叠保护反应的分子和表观遗传基础仍不清楚。从这个角度来看，我们讨论了交叉保护机制，并为其在提高对农业害虫中各种自然和人为压力源的耐受性方面的潜在作用提供了论据。通过借鉴关于单一和多重应激源研究的现有文献，我们概述了促进交叉保护相互作用的过程，包括表观遗传修饰，这些在昆虫应激反应中未得到充分研究。最后，我们讨论了交叉保护对害虫管理的影响，重点关注杀虫剂与气候变化相关的高温之间交叉保护的后果。鉴于农业生态系统中害虫的集中管理方式多种多样，我们建议检查多种压力源的作用对于了解农业害虫的广泛适应性可能很重要。© 2022 作者。Pest Management Science由 John Wiley & Sons Ltd 代表化学工业协会出版。
