ABSTRACT
Old house borer, Furniture beetle, Deathwatch beetle, and Powder post beetle are common dry-wood-boring insects occurring throughout Europe. In The Netherlands, as in many other European countries, a substantial part of the attacks by these insects is countered with biocidal products. At SHR a process was started to develop a method for a 'Woodworm Detector', for which it was decided that acoustic emissions (AE) would be useful. Detection of insect activity using AE has been the subject of many earlier experiments and tests. For Hylotrupes, all active blocks were used, measuring AE events each time consecutively for 15-20 minutes on each block, coupling and leaving them inside the cabinets as much as possible. For Anobium and Xestobium the most active sample was chosen and AE events measured continuously on the one sample staying inside the cabinet.
