Pheromone plasticity is widely observed in insects and enhances their survival, adaptation, and reproductive success. Aggregation pheromones, which cause notable individual aggregation and consequently impact agriculture and human life, are renowned for their special function. Here, we present a review of research progress regarding pheromone plasticity in three typical aggregative insects: locusts, bark beetles, and cockroaches. These insects are major pest species with considerable impacts on the social economy and public health. Numerous studies have demonstrated the plasticity of aggregation pheromones in different populations of these insect species. Although pheromone chemicals and compositions vary across the three groups, the plasticity of aggregation pheromones is significantly impacted by population density, location, food resources, and gut symbiotic microorganisms, indicating the complexity of pheromone plasticity regulated by multiple factors. Finally, we discuss the potential application of pheromone plasticity in basic research and pest management.
信息素可塑性在昆虫中广泛存在，可提高它们的生存、适应及繁殖成功率。聚集信息素能引起显著的个体聚集，进而影响农业和人类生活，以其特殊功能而闻名。在此，我们综述了三种典型聚集性昆虫——蝗虫、小蠹虫和蟑螂——信息素可塑性的研究进展。这些昆虫是对社会经济和公众健康有重大影响的主要害虫种类。众多研究已证明这些昆虫不同种群中聚集信息素的可塑性。尽管这三类昆虫的信息素化学物质和成分有所不同，但聚集信息素的可塑性受到种群密度、地理位置、食物资源和肠道共生微生物的显著影响，这表明多因素调控的信息素可塑性具有复杂性。最后，我们讨论了信息素可塑性在基础研究和害虫治理中的潜在应用。
