Boring as an important class of forest pests pests can cause devastating damage on tree hazards hidden and tree damage response lag is often little success so early monitoring. In this paper, sound detection method on the the valens adult reptiles and larvae feeding acoustic signal, Semanotus alternatus adult crawling acoustic signal, larvae and crawling sound signal, Anoplophora alternatus adult stress and feeding of the acoustic signal, Apriona feeding and crawling sound signal explore, and obtained the following results: (1) use of self-organized the pests sound signal acquisition systems (including AED-2000 portable sound detectors of R-09 portable recorder, Sony monitor headphones, Ⅰ BM Z60t notebook ) can be completed pests vibrating sound signal acquisition, signal analysis system (MATLAB Signal Processing Toolbox and Goldwave audio processing software) to complete the post-processing of the signal, the response signal in the time domain, frequency domain and time-frequency domain characteristics . By analysis of the of different pests vibration acoustic signal time-frequency characteristics, summed up the differences of the the vibrating sound signal between different pests. The results show that each insect acoustic signal has its own unique frequency characteristics within the same family of insects between different families of insects have differences, some differences. Tests showed the feasibility of using sound monitoring technology Boring Beetle on tree early monitoring. ② adult crawling sound as \rate, etc., the individual motion faster, shorter pulse duration, the pulse interval is short, and vice versa. ③ feeding Apriona, acoustic signal pulse duration shorter, for the 30.00-40.00ms, while the valens Semanotus longicorn larvae feeding sound signal pulse duration is longer, for the 50.00-130.00ms: Apriona feeding acoustic signal frequency is higher, 843.80Hz, the valens signal frequency 516.00Hz, Semanotus bifasciatus larvae acoustic signal frequency compared 187.50Hz; ④ larvae crawling sound signal instability is no obvious trend of the time domain; frequency domain features statistics show that the the larva crawling sound signal frequency range is narrow, clocked at less than feeding acoustic signal, which, of Semanotus longicorn larvae crawling sound signal frequency 187.50Hz, the crawling sound signal frequency Apriona 140.60Hz.
