由于气候变化，极端温度事件的频率和强度正在增加。这些事件威胁到昆虫，包括传粉媒介、害虫和疾病媒介。昆虫的临界温度限制可以通过驯化来提高，但在极端温度下可塑性有助于生存的证据是有限的。在这里，使用1374个效应量，74项研究和102个物种的荟萃分析，我们表明热极限可塑性是普遍的，但通常很弱：驯化温度每上升1 °C，临界热最大值增加0.09 °C;每下降1 °C，临界热最小值降低0.15 °C。此外，小，但显着的出版物偏见表明，可塑性的大小是稍微高估。我们发现幼年昆虫比成年昆虫更具可塑性，这表明昆虫的生理反应在个体发育过程中是不同的。总的来说，我们表明，在极端气候事件中，临界热极限可塑性对昆虫的益处可能有限，但我们需要在代表性不足的类群和地理区域进行更多的研究。生物体适应高温的能力越来越受到气候变化的考验。这项全球荟萃分析表明，昆虫热极限的可塑性很普遍，但不太可能跟上气候变化的步伐。
Extreme temperature events are increasing in frequency and intensity due to climate change. Such events threaten insects, including pollinators, pests and disease vectors. Insect critical thermal limits can be enhanced through acclimation, yet evidence that plasticity aids survival at extreme temperatures is limited. Here, using meta-analyses across 1374 effect sizes, 74 studies and 102 species, we show that thermal limit plasticity is pervasive but generally weak: per 1 °C rise in acclimation temperature, critical thermal maximum increases by 0.09 °C; and per 1 °C decline, critical thermal minimum decreases by 0.15 °C. Moreover, small but significant publication bias suggests that the magnitude of plasticity is marginally overestimated. We find juvenile insects are more plastic than adults, highlighting that physiological responses of insects vary through ontogeny. Overall, we show critical thermal limit plasticity is likely of limited benefit to insects during extreme climatic events, yet we need more studies in under-represented taxa and geographic regions. The ability of organisms to acclimate to high temperatures is increasingly put to test by climate change. This global meta-analysis shows that plasticity of thermal limits in insects is widespread but unlikely to keep pace with climate change.
