It is widely recognized that the phenology of insects, of which the life activities are closely tied to temperature, is shifting in response to global climate warming. This study aimed to investigate the impacts of climate change on the phenology of Matsumura, 1900 (Lepidoptera: Carposinidae) across large temporal and spatial scales, through collecting and systematically analyzing historical data on the pest's occurrence and population dynamics in China. The results showed that for overwintering adults, the first occurrence date in eastern, northwestern, and northern China has significantly advanced, along with the population peak in eastern and northwestern China. At the provincial level, the population peak date in Shandong province has also moved significantly earlier, as well as the population peak date in Shandong and Shaanxi and the end occurrence date in Ningxia. However, the population peak date in Jilin has experienced a delayed trend. For first-generation adults, the first occurrence date in northeastern, eastern, and central China has notably advanced, while the first appearance date in northwestern and northern China has significantly delayed. Additionally, the population peak in northwestern China has experienced significant delays, along with the final occurrence in northeastern and northwestern China. At the provincial level, the first occurrence date in Liaoning, Shandong, and Shanxi has significantly advanced, while Hebei has demonstrated a significant delay. The population peak time in Gansu and Shaanxi has displayed significant delays, and the end occurrence date in Liaoning, Shanxi, and Shaanxi has also shown significant delays. Furthermore, these findings integrated with the Pearson correlation results reveal spatial heterogeneity in 's phenological responses to climate warming at both regional and provincial scales. The phenology of and their changing patterns with climate warming vary by geographical location. This study provides valuable information for the future monitoring, prediction, and prevention of peach fruit moths in the context of climate warming.
人们普遍认识到，昆虫的物候（其生命活动与温度密切相关）正在随着全球气候变暖而发生变化。本研究旨在通过收集和系统分析中国该害虫发生及种群动态的历史数据，在大的时间和空间尺度上调查气候变化对桃蛀螟（1900年松村，鳞翅目：蛀果蛾科）物候的影响。结果表明，对于越冬成虫，中国东部、西北部和北部的首次出现日期显著提前，中国东部和西北部的种群高峰期也提前。在省级层面，山东省的种群高峰期日期也显著提前，山东和陕西的种群高峰期日期以及宁夏的终见日期也是如此。然而，吉林省的种群高峰期日期呈延迟趋势。对于第一代成虫，中国东北、东部和中部的首次出现日期显著提前，而中国西北和北部的首次出现日期显著延迟。此外，中国西北部的种群高峰期显著延迟，中国东北和西北部的终见期也是如此。在省级层面，辽宁、山东和山西的首次出现日期显著提前，而河北则显著延迟。甘肃和陕西的种群高峰期时间显著延迟，辽宁、山西和陕西的终见日期也显著延迟。此外，这些结果与皮尔逊相关性结果相结合，揭示了桃蛀螟在区域和省级尺度上对气候变暖的物候响应存在空间异质性。桃蛀螟的物候及其随气候变暖的变化模式因地理位置而异。本研究为气候变暖背景下桃蛀螟未来的监测、预测和防治提供了有价值的信息。
