Low temperatures are rarely experienced in isolation. The impacts of low temperatures on insects can be exacerbated or alleviated by the addition of other environmental factors, including, for example, desiccation, hypoxia, or infection. One way in which environmental factors can interact is through cross-talk where different factors enact common signaling pathways. In this review, I highlight the breadth of abiotic and biotic factors that can interact with low-temperature tolerance in both natural and artificial environments; and discuss some of the candidate pathways that are possibly responsible for cross-talk between several factors. Specifically, I discuss three interesting candidates: the neurohormone octopamine, circadian clock gene vrille, and microbes. Finally, I discuss applications of cross-talk studies, and provide recommendations for researchers.
低温很少单独出现。低温对昆虫的影响会因其他环境因素的加入而加剧或减轻，这些因素包括例如干燥、缺氧或感染。环境因素相互作用的一种方式是通过不同因素激活共同信号通路的相互影响。在这篇综述中，我强调了在自然和人工环境中可与低温耐受性相互作用的非生物和生物因素的广度；并讨论了可能导致几种因素之间相互影响的一些候选通路。具体来说，我讨论了三个有趣的候选因素：神经激素章鱼胺、生物钟基因vrille和微生物。最后，我讨论了相互影响研究的应用，并为研究人员提供建议。
