摘  要  蝗虫大规模聚集造成的灾害对农牧业、经济和环境构成重大威胁。蝗灾发生的生物学基础是蝗虫可以由散居型向群居型转变，进而大规模聚集暴发成灾。群聚信息素被认为在蝗虫群聚过程中起到重要作用，其研究历经50余年，近年来取得了一系列重要的成果。本文描述了群聚信息素的基本定义与特征并以此类推蝗虫群聚信息素应具备的基本特点；系统综述了蝗虫群聚信息素的研究历程，包括化合物的鉴定、电生理检测与行为验证等；同时分析了过去群聚信息素研究存在的局限与现今鉴定并验证群聚信息素应具备的条件；最后对蝗虫群聚信息素未来的研究方向与应用做出展望。

Abstract  Locust plagues continue to pose a major threat to global agriculture, the economy and the environment. These plagues arise when locusts change from the solitary to the gregarious phase. An aggregation pheromone is considered to play a critical role in this transition and has been the subject of research for over 50 years. This paper briefly describes the characteristics of the locust aggregation pheromone and reviews recent progress in research, including recent breakthroughs in compound identification, electrophysiological recording and behavioral assays. The shortcomings and limitations of past research, and requirements for the identification and verification of the aggregation pheromone in current research, are also discussed. Finally, prospects for future research and the application of the locust aggregation pheromone to locust prevention are outlined.
