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 mate- riarius and G. sulcatus were detected using sound detection method. It was concluded that the feeding and crawling acoustic signals of G. materiarius and G. sulca- tun were significantly different, and the acoustic signals were greatly different even in the same species. In addition, the signal pulse duration and dominant frequen- cy were significantly different. Therefore, it is feasible to monitor trunk borers using sound detection technology.展开更多
