蓟马信息素研究及应用进展

Advances in the research and application of thrips pheromones

蓟马是农作物和园艺作物上常见的重要害虫,其通过直接取食和间接传播病毒给作物造成了巨大的经济损失。应用蓟马信息素是蓟马害虫绿色防控的重要措施。本文综述了蓟马产生的信息化学物质的研究进展,概述了已报道的蓟马肛门分泌物的化学组分及其功能,介绍了已鉴定的蓟马报警信息素、聚集信息素、接触信息素和抑性欲信息素的主要成分、分泌部位、作用功能和合成方法,讨论了信息素在蓟马害虫防控中的应用潜能,并展望了目前蓟马信息素研究中存在的问题和未来的发展方向,以期为蓟马害虫信息素的合理应用提供指导。

Thrips are important pests of agricultural and horticultural crops, causing enormous economic losses by direct feeding and indirect transmission of the plant-pathogenic virus. Pheromones have been used as green control methods for thrips management. In this article, the reported semichemicals produced by thrips were reviewed, including identified anal secretions and pheromones. Besides, the active components, sites of biosynthesis and deposition, synthetic methods and functions of alarm pheromone, aggregation pheromone, contact pheromone and anti-aphrodisiac pheromone were summarized.The potential of pheromones for thrips management was also discussed. Finally, current problems and potential research directions of thrips pheromones were discussed, which could help better exploit thrips pheromones for pest management.
