In recent years, maize aphids have become the most destructive pests in Jilin Province, Northeast China. However, the patterns of aphid activity remain poorly understood, with systematic monitoring efforts for Aphididae in this region remain insufficient. During 2018 to 2022, multiple methods were used to monitor aphid movements, including a suction trap network in Jilin Province, drones equipped with traps, and adjustable-height yellow sticky traps. In total, 82 aphid species were identified using the suction trap network. In the maize field, 47 and 51 aphid species were captured using drone traps and adjustable-height yellow sticky traps, respectively. Eight aphid species were documented as damaging maize, with field observations of winged and wingless aphids revealing four key pests: Sitobion miscanthi (Takahashi) (Hemiptera: Aphididae), Rhopalosiphum maidis (Fitch), Aphis gossypii Glover, and Rhopalosiphum padi L. Their migration periods, spatial distributions, local population dynamics, and distribution were recorded. In the field, S. miscanthi was occasionally observed during June to October. For A. gossypii, peak activity occurred during June to July, corresponding to the maize ear development stage, whereas R. maidis and R. padi occurrence peaked from August to September, aligning with the maize reproductive growth stage. The study also identified the population sources of these four aphids. Trajectory simulations for S. miscanthi and R. maidis showed annual invasions by migrants from southern China and the Korean Peninsula. These findings are critical for predicting aphid outbreaks in the region and for informing maize cultivation strategies in affected areas.
近年来，玉米蚜虫已成为中国东北吉林省最具破坏力的害虫。然而，蚜虫的活动模式仍鲜为人知，该地区对蚜科的系统监测工作仍不足。在2018年至2022年期间，采用了多种方法监测蚜虫的移动，包括吉林省的吸虫器网络、配备诱捕器的无人机以及可调节高度的黄色粘虫板。使用吸虫器网络总共鉴定出82种蚜虫。在玉米田中，使用无人机诱捕器和可调节高度的黄色粘虫板分别捕获了47种和51种蚜虫。记录了8种对玉米有危害的蚜虫，对有翅和无翅蚜虫的田间观察揭示了4种主要害虫：禾谷缢管蚜（高桥）（半翅目：蚜科）、玉米缢管蚜（费奇）、棉蚜（格洛弗）和麦长管蚜（林奈）。记录了它们的迁飞期、空间分布、当地种群动态和分布情况。在田间，6月至10月偶尔能观察到禾谷缢管蚜。对于棉蚜，活动高峰期出现在6月至7月，与玉米穗发育阶段相对应，而玉米缢管蚜和麦长管蚜的发生高峰期在8月至9月，与玉米生殖生长阶段一致。该研究还确定了这4种蚜虫的种群来源。对禾谷缢管蚜和玉米缢管蚜的轨迹模拟显示，每年都有来自中国南方和朝鲜半岛的迁徙者入侵。这些发现对于预测该地区蚜虫爆发以及为受灾地区的玉米种植策略提供信息至关重要。
