<i>Spodoptera exigua</i> is a significant pest of crops, but its ability to adapt to new climates remains poorly understood. This study investigates how temperature, light cycle, and humidity affect the beet armyworm’s life cycle. By analyzing 264 data points from 33 published studies, we found that warmer temperatures, particularly above 20°C, significantly enhance the beet armyworm's physiological functions. As temperatures increase, the developmental stages shorten, egg-laying decreases, and the pupal stage shortens, which leads to longer adult lifespan. The study identified the optimal environmental conditions for each life stage of the beet armyworm, providing crucial insights into its adaptability in changing climates. These findings are important for predicting beet armyworm population dynamics and developing better pest management strategies.

甜菜夜蛾（Spodoptera exigua）是一类重要的农业害虫，但其适应新型气候的能力仍未得到充分解析。本研究围绕温度、光周期与湿度对甜菜夜蛾生活史的影响展开探究。本研究整合了33项已发表研究中的264组数据点，结果发现：较高的温度（尤其是20℃以上）可显著提升甜菜夜蛾的生理机能。随着温度升高，其各发育阶段时长缩短、产卵量下降，且蛹期缩短，进而使得成虫寿命延长。本研究明确了甜菜夜蛾各生活阶段的最优环境条件，为解析其在气候变化下的适应性提供了关键理论依据。上述研究结果对于预测甜菜夜蛾种群动态、优化害虫防治策略具有重要指导意义。
