Wood preservatives - Determination of the protective effectiveness against Anobium punctatum (De Geer) by egg-laying and larval survival - Part 2: Application by impregnation (Laboratory method)

This standard establishes a standardized laboratory procedure for evaluating the protective efficacy of wood preservatives against the bark beetle, specifically Tomicus piniperda (De Geer). Focusing on the second part of a comprehensive series, the document details the impregnation method utilized to assess the impact of treatment on egg-laying behavior and the subsequent survival rates of larvae. By defining specific test conditions, specimen preparation, and data recording protocols, the text ensures consistency across different testing facilities. The methodology is designed to measure how effectively preservative solutions penetrate the wood matrix and deter or eliminate the insect population during early developmental stages. This approach allows for controlled comparisons between various chemical formulations and application techniques under consistent environmental parameters. The outlined procedures facilitate the generation of reproducible data essential for product development and regulatory assessment within the field of timber protection. Adherence to these defined steps ensures that results obtained in laboratory settings accurately reflect the potential performance of wood treatment solutions against this specific pest species.
