[Effects of rice volatile infochemicals on insects]

Plant volatile is not only the key of the relationship among plant, herbivore and its natural enemy, but also the foundation for the theory and practice of pest manage. In this paper, the chemical characteristic of rice volatile and its function among herbivore and its natural enemy were reviewed. The application and development direction of rice volatile infochemicals were proposed. Two directions to study the rice volatile infochemicals, which could be used in pest control, were also discussed. One was the physiology and biochemistry of little molecule signals, which was the key of rice second metabolize, and the other was the base of sense, identify and learn of pest insect to rice volatile infochemicals.
