植物通过释放的挥发性有机化合物（Volatile organic compounds，VOCs）介导其与周围环境中同种和不同种生物的相互作用，从吸引传粉、种子传播媒介，到保护自己免受植食性动物、病原菌和寄生生物的侵害等。植物挥发物尤其是虫害诱导挥发物是近30年来化学生态学和植物保护领域的研究热点。本文综述了近年来植物挥发物介导的种内与种间关系的研究进展，主要概括了植物挥发物的基本特征，植物挥发物在调控植物种内及种间、植物与昆虫、植物-害虫-天敌三营养级关系、以及植物与微生物互作中的生态学功能，并对其在农业生产中的应用和前景进行分析，总结这一领域尚未解决和亟需深入研究的问题，为植物挥发物应用于有害生物的控制提供理论依据。
Plants release a variety of volatile organic compounds (VOCs) to mediate intra- and inter-specific interactions with other organisms in the surrounding environment. VOCs are involved in attracting pollinators and seed dispersers, protecting plants from invasion by herbivores, pathogens and parasites and so on. The study of plant volatiles, especially herbivore-induced plant volatiles, has been a research hotspot in the fields of chemical ecology and plant protection for nearly three decades. In this paper, recent advances in the study of plant volatiles-mediated intra- and inter-species relationships are reviewed. We summarized the basic characteristics of plant volatiles and their ecological roles in regulating intra- and inter-species plants, plant-insect, plant-herbivore-natural enemy tritrophic interactions and plant-microbe interactions. We also analyzed the application and prospect of plant volatiles in agricultural production, summarized the unresolved issues in this field and discussed the issues for further research, so as to provide a theoretical basis for the application of plant volatiles in pest control.
