Yunnan is located on the southwest border of China, with a complex geographical environment and rich biodiversity, which is the first stop for many migratory pests to enter China. In recent years, has migrated into China through the China-Laos border line. The migratory has shown typical characteristics of migratory locusts, which has seriously jeopardized the ecological security, biosecurity and food security of China. In order to prevent and control from the source as soon as possible, this study used hotspot analysis and trajectory analysis to clarify the migration dynamics, source regions and migration corridors of . The results showed that the migratory was mainly distributed in the towns of Jiangcheng County, and the source regions were concentrated in Phongsaly, Laos. There are three cross-border migration corridors of , among which the Laos-Niuluohe border migration corridor running through the entire migration cycle is the most important corridor. The study answered three key questions about the prevention and control of . Ascertaining when arrived at Yunnan, where it came from, and where the population then went will greatly improve the efficiency of the prevention and control of as well as provide a theoretical basis for subsequent monitoring and early warning.
云南位于中国西南边陲，地理环境复杂，生物多样性丰富，是众多迁飞性害虫进入中国的第一站。近年来，[某种害虫]通过中老边境线迁入中国。该迁飞性[害虫]呈现出典型的飞蝗特征，严重危及中国的生态安全、生物安全和粮食安全。为尽快从源头防控[该害虫]，本研究运用热点分析和轨迹分析，以阐明[该害虫]的迁移动态、源区和迁飞通道。结果表明，迁飞性[该害虫]主要分布在江城县城的乡镇，源区集中在老挝丰沙里省。[该害虫]有三条跨境迁飞通道，其中贯穿整个迁飞周期的老挝-牛洛河边境迁飞通道是最重要的通道。该研究回答了关于防控[该害虫]的三个关键问题。确定[该害虫]何时抵达云南、来自何处以及之后虫群去向，将极大提高[该害虫]的防控效率，并为后续监测和预警提供理论依据。
