Wood preservatives - Determination of the toxic values against larvae of Hylotrupes bajulus (Linnaeus) - (Laboratory method)

This technical document establishes a precise laboratory methodology for evaluating the toxic effects of wood preservatives against larvae of Hylotrupes bajulus, a significant pest known as the house longhorn beetle. The procedure outlines the specific conditions required to expose wood samples treated with various protective agents to infestation by these larvae under controlled laboratory settings. It details the preparation of test specimens, the criteria for infestation, and the protocols for assessing mortality and damage levels after a defined exposure period. The objective is to provide a standardized approach for manufacturers and testing laboratories to determine the efficacy of chemical treatments designed to prevent timber degradation caused by this insect. By adhering to the defined steps, users can generate comparable data regarding the resistance of treated wood, ensuring consistency in performance evaluation across different testing environments. This method focuses exclusively on the toxicological assessment within a laboratory framework, offering a reliable basis for quality control and regulatory compliance in the field of wood protection.
