Abstract：
Insects in agroecosystems contend with many stressors - e.g., chemicals, heat, nutrient deprivation - that are often encountered at low levels. Exposure to mild stress is now well known to induce hormetic (stimulatory) effects in insects, with implications for insect management, and ecological structure and function in agroecosystems. In this review, we examine the major ecological niches insects occupy or guilds to which they belong in agroecosystems and how hormesis can manifest within and across these groups. The mechanistic underpinnings of hormesis in insects are starting to become established, explaining the many phenotypic hormetic responses observed in insect reproduction, development, and behavior. Whereas potential effects on insect populations are well supported in laboratory experiments, field-based hypothesis-driven research on hormesis is greatly lacking. Furthermore, because most ecological paradigms are founded within the context of communities, entomological agroecologists interested in hormesis need to \'level up\' and test hypotheses that explore effects on species interactions, and community structure and functioning. Embedded in this charge is to continue experimentation on herbivorous pest species while shifting more focus towards insect natural enemies, pollinators, and detritivores - guilds that play crucial roles in highly functioning agroecosystems that have been understudied in hormesis research. Important areas for future insect agroecology research on hormesis are discussed.
摘要：
农业生态系统中的昆虫与许多压力源抗衡-例如，化学品,热,营养剥夺-经常在低水平遇到。现在众所周知，暴露于轻度胁迫会在昆虫中引起恐怖（刺激）效应，对昆虫管理有影响，农业生态系统的生态结构和功能。在这次审查中,我们研究了昆虫在农业生态系统中所占据的主要生态位或它们所属的行会，以及如何在这些群体中和这些群体中表现出来。昆虫中刺激的机制基础开始确立，解释在昆虫繁殖中观察到的许多表型角化反应，发展,和行为。尽管对昆虫种群的潜在影响在实验室实验中得到了很好的支持，基于领域的假设驱动研究是非常缺乏的。此外，因为大多数生态范式都是在社区的背景下建立的，对hormesis感兴趣的昆虫学农业生态学家需要“升级”并测试探索对物种相互作用影响的假设，以及社区结构和功能。嵌入这项指控的是继续对草食性害虫物种进行实验，同时将更多注意力转移到昆虫天敌上，传粉者,和有害土壤-行会在高度功能的农业生态系统中起关键作用，在hormesis研究中对此进行了充分研究。讨论了未来昆虫农业生态学研究的重要领域。
