摘要

As an emerging technology for pest monitoring,sound detection technology has the unique advantages in the field of plant quarantine. Experts at home and abroad have done lots of researches on sound detection technology for trunk borers,and achieved good results. The audible signals of adult Gnathotrichus materiarius and G. sulcatus were detected using sound detection method. It was concluded that the feeding and crawling acoustic signals of G. materiarius and G. sulcatus were significantly different,and the acoustic signals were greatly different even in the same species. In addition,the signal pulse duration and dominant frequency were significantly different. Therefore,it is feasible to monitor trunk borers using sound detection technology.
