Abstract

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 Carposina sasakii 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 C. sasakii's phenological responses to climate warming at both regional and provincial scales. The phenology of C. sasakii 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.

气候变化对桃果蛾发生期的影响:中国的区域视角
人们普遍认为,昆虫的生命活动与温度密切相关,昆虫的物候正在随着全球气候变暖而变化。本研究旨在通过收集和系统分析鲤鱼尺蠖(鳞翅目:鲤鱼科)在中国发生和种群动态的历史数据,研究气候变化对其物候在大时空尺度上的影响。结果表明,对于越冬成虫而言,华东、西北和华北地区的初发期明显提前,华东和西北地区的种群高峰也明显提前。在省级层面,山东省的种群高峰期、山东和陕西的种群高峰期以及宁夏的结束发生期也明显提前。然而,吉林省的人口高峰日期出现了延迟趋势。就第一代成年人而言,东北、华东和华中地区的首次出现日期明显提前,而西北和华北地区的首次出现日期则明显推迟。此外,西北地区的人口高峰与东北和西北地区的最终出现时间都出现了明显的延迟。在省级层面,辽宁、山东和山西的首次出现时间明显提前,而河北则出现了明显的延迟。甘肃和陕西的人口高峰期明显延迟,辽宁、山西和陕西的终结发生期也明显延迟。此外,这些发现与皮尔逊相关性结果相结合,揭示了沙蚕在区域和省级尺度上对气候变暖物候反应的空间异质性。C.sasakii的物候及其随气候变暖的变化规律因地理位置而异。这项研究为今后在气候变暖背景下监测、预测和预防桃实蛾提供了宝贵的信息。

期刊介绍: Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
