Initial comparative tests of a method for the detection of house longhorn beetle larvae (Hylotrupes bajulus L.) were carried out by means of recording the acoustic effects caused by these insects, as well as another instrumental method based on the use of X-ray pictures. Insofar as the X-ray method brings completely reliable results as regards the detection of the presence of fully-grown house longhorn beetle larvae in wood, the accuracy of situation assessment based on the electro-acoustic method is estimated to be approximately 70-80%, based on the results of the research presented herein. In this research the accuracy of situation assessment is understood as the correct determination of an estimated number of larvae and their condition. The differences in situation assessment accuracies using both methods were statistically verified by means of the Czebyszew method. Since the tests were initial in nature without the use of standard patterns, as these have not been developed yet, the obtained results are considered highly satisfactory.
