The invention relates to a system and method for detecting xylophages, capturing their sounds by means of one or more terminals (TS1,TS2,TS3,TS4) installed in a wood structure comprising a DSP executing a peak detection algorithm to obtain acoustic data relating to the presence of the insects, which are transmitted by radio frequency to a remote central control station (10) for the analysis and access to those data through a web interface and one or more user access interfaces for connecting with user terminal equipment (TU1,TU2,TU3,TU4) by means of USB, PCMCIA, Ethernet, GSM, GPRS, UMTS,...
