Abstract: Plants emit synomone by herbivore feeding to attract natural enemies to protect themselves. Herbivore-induced synomone indicates the presence of host clearly and specifically and plays an important role to the location of natural enemies in the search of long distance. Different plants and herbivores can induce different chemicals, so the production of synomone has the specificity of species. In addition, spatial and temporal factors regulate the production of synomone. Research on chemical ecology of synomone shows that the main components of synomone are “green leaf odor”, terpene and indole.β-Glucosidase in caterpillars' oral secretion is an elicitor of synomone. But some plants release synomone systemically and elicitor of which has not been known yet. There are three possible pathways for plants to synthesize synomone, namely isoprenoid pathway, fatty acid/lipoxygenase pathway and shikimic acid/tryptophan pathway.
