Abstract: Adopting the self-made feeble sound monitoring system, authors studied the sounds and their features of Empoasca vitis. The results indicated that, the nymph and the female adult alone didn’t sound but the male adult could emit the vibration sounds transmitted through host-plant and used in the communication of intra-species. Altogether, 3 kinds of sound were recorded, that were male’s common sounds, rivalry sounds and courtship sounds which emitted when the sexes were put together. Meanwhile, authors also analysis the waveform feature of the 3 acoustic signals. The study on the leafhopper’s acoustic behavior may offer theory basis for developing new method of controlling Empoasca vitis.

Key words: Empoasca vitis, acoustic signals, communication
