水稻挥发物在调控害虫中的作用及其应用前景

Prospects for the application of rice volatiles in pest control

植物挥发物作为生态系统中各生物间信息传递的载体在影响生物进化及生物群落组成中发挥着重要作用。剖析植物挥发物的主要化学组分及其生态学功能,不仅能从一个侧面揭示生物间的协同进化,而且可为害虫的可持续治理提供有效的绿色防控技术。为此,本文围绕水稻挥发物主要组分与合成途径、虫害诱导水稻挥发物合成的调控机理、水稻挥发物的生态学功能及应用前景等方面,对国内外的最新研究成果进行综述,提出了今后的研究方向,并推动水稻挥发物在害虫防控中的应用。

Plant volatiles,transmit information between taxa and thereby play an important role in evolution and community composition.Deciphering the main chemical components of plant volatiles and their ecological functions can not only reveal the co-evolution of organisms,but also identify potentially effective,environmentally-friendly,compounds for sustainable pest management.This paper summarizes the latest progress in research on rice volatiles,mainly focusing on their components and biosynthesis pathways,the regulatory mechanism underlying the biosynthesis of herbivore-induced volatiles,their ecological function and prospects for their application in pest control.Directions for research future are suggested to promote the application of rice volatiles in pest control.
