摘  要  植食性昆虫利用种内化学信息物质进行求偶和交配，从而维持其田间的种群数量；植物在识别植食性昆虫的为害后，可产生直接和间接防御反应来抵御植食性昆虫的为害。相应地，植食性昆虫亦可利用植物的虫害诱导化学信息物质选择嗜好寄主，从而提高其生长适应度。茶树是多年生常绿木本经济作物，常年病虫害发生严重。据不完全统计，茶树病虫害每年给茶叶带来的经济损失就高达20%-50%，严重影响茶产业的绿色、健康和可持续发展。近20年，科研工作者在调控茶树害虫行为和种群动态的主要化学信息物质、作用方式及调控机理等方面展开了较为系统的研究，取得了一些研究成果。本文着重从茶树害虫性信息素的种类及其特异性、寄主和非寄主植物挥发物对害虫种群的调控作用等方面对目前的研究进展进行了综述，并对利用挥发性化学信息物质构建茶树害虫的生态调控技术进行了展望，以期为茶树害虫化学信息物质的研究提供参考。

Abstract  Herbivorous insects use intraspecific semio-chemicals for courtship and mating whereas plants can produce direct and indirect chemical defenses after detecting the damage caused by insect pests. Herbivorous insects can also use these defensive chemicals produced by plants to identify hosts. Tea is a perennial, evergreen, woody, cash crop that is adversely affected by disease and insect pests throughout the year. The economic losses to tea production caused by diseases and pest insects are as high as 20%-50% per annum, which seriously hinders the development of a sustainable and environmentally-friendly tea industry. In the past 20 years, researchers have carried out systematic research on the main semio-chemicals, their modes of action and the mechanisms that regulate the behavior and population dynamics of tea pest insects. This paper mainly reviews current progress in the identification and utilization of tea pest insects' sex pheromones, the role of host and non-host plants in the regulation of pest insect populations, and discusses prospects for the ecological regulation of insect tea pests using pheromones.
