Abstract: The study was done to provide the theoretics for the further study of VOCs(Volatile organic compounds) on the selection of insect-defence species,mechanism of insect-defence,ecological control,and ecological restoration of forest. The current advance was reviewed of the species of VOCs in trees and its functions of VOCs on insects. Tree VOCs had dual roles in control of herbivore-insect: attracting the insects to locate and attack host trees,and providing defensive system for trees,and included isoprene,monoterpene and other reactive VOCs,et al., whose emissions were affected by biotic and abiotic factors. VOCs' functions on insects included the attraction and repellency of insects and its attraction to natural enemies. However,it is difficult to isolate and identify the specific VOCs to insects,which needs to discover the key elements regulating the emission of VOCs at the molecular level. Finally,the foreground of VOCs on ecological controls of tree pests suggested that it will be theoretical and practical for the new methods of defending and controlling insects,and selection of insect-defence trees by the' bridge' of VOCs.

Key words: Volatile organic compounds, Insect-defence, Attraction, Repellency, Trees
