【目的】为探明中国与哈萨克斯坦（简称中哈）两国边境区域空中昆虫的群落组成、种群动态变化以及飞行特征。【方法】本研究于2023-2024年6-8月，在新疆塔城边境区域综合运用昆虫雷达、高空测报灯和地面诱虫灯对空中昆虫开展系统监测，并对其优势物种进行重点研究。【结果】结果表明：空中昆虫物种组成以鞘翅目（55.92%）和鳞翅目（30.17%）为优势类群，蜉蝣目占比最低（0.03%）。旋歧夜蛾Scotogramma trifolii（Hufnagel）和棉铃虫Helicoverpa armigera（Hübner）作为优势种群，二者飞行高度均集中在200~300 m，飞行方向均以东北或东偏北方向为主。其中，旋歧夜蛾高峰期、夜间飞行时间和飞行速度分别为2023年7月10日、23:00-次日1:00、0~6 m/s，棉铃虫则依次为2024年8月25日、22:00-次日2:00、14~16 m/s。【结论】本研究明确了中哈边境空中昆虫的群落组成以及优势类群的季节动态规律和空中行为特征，为利用昆虫雷达实现中哈边境迁飞害虫的监测预警和区域联防具有重要实践价值。

英文摘要:

【Aim】This study aimed to investigate the community composition, population dynamics,and flight characteristics of airborne insects in the China-Kazakhstan (hereafter referred to as Sino-Kazakh) border region.【Methods】A systematic monitoring study was conducted from June to August in 2023 and 2024 in the Tacheng border area of Xinjiang. The research integrated insect radars, high-altitude light traps and ground light traps. The dominant species were also given special attention.【Results】The results revealed that Coleoptera (55.92%) and Lepidoptera (30.17%) were the dominant taxonomic groups in the airborne insect community, while Ephemeroptera accounted for the lowest proportion (0.03%). The dominant species were identified as Scotogramma trifolii (Hufnagel) and Helicoverpa armigera (Hübner). The flight heights of both species were primarily concentrated between 200 m and 300 m, with their main flight directions being northeast or east-northeast. Specifically, the peak period, nocturnal flight time, and flight speed for S. trifolii were July 10, 2023; 23:00-01:00 (the next day); and 0~6 m/s, respectively. In contrast, for H. armigera, these parameters were August 25, 2024; 22:00-02:00 (the next day); and 14~16 m/s, respectively.【Conclusion】This study further clarifies the community composition, seasonal dynamics, and aerial behavioral characteristics of dominant airborne insect groups along the Sino-Kazakh border. The findings hold significant practical value for utilizing entomological radar in the monitoring, early warning, and regional cooperative management of migratory pests in this border region.
