Abstract: Since the late of 1980s, the bioassay, including the use of olfactometer, proved that aphids orientate to plants by the means of the volatiles of host plants, and natural enemies orientate to aphids by the searching kairomone. The activity of semiochemicals among plant, aphid and natural enemy was detected by Electroantennograph(EAG), Single cell recording techniques(SCR)and SCR coupled to Gas chromatography(GC-SCR). The composition and spatial structure of semiochemicals were identified by combined GC-Mass spectrometry and infrared spectrum(GC-MS-IS). The sex pheromones of the most of aphids were the synergistic mixture of 2 or 3 kinds of nepetalactols. The main components of alarm pheromones were(E)-(-farnesene(EBF). Electrical penetration graph(EPG)exhibited eight types of waveforms which represent different physiological activities, including aphid stylets(probing, sucking, secreting accompanied by the excreting of honeydew, and revealed the spectrum difference between resistant and susceptible tea varieties to aphids. Results also showed that the contents of nutritional components(such as amino acides)and resistance-determining components in plant were related to aphid population density.
