Determination of protective efficacy against Anobium punctatum by observing egg laying and larval survival rates

As part of the marketing authorisations for European biocidal products, these two tests are referenced in standard EN 599-1 and are among the tests required.

Standard NF EN 49-1 is suitable for products intended for surface application. The treated wood is prepared and placed in contact with pairs of Anobium punctatum. The females’ egg-laying is assessed at the start of the test. The treated wood blocks are then placed in incubation for 26 or 52 weeks. At the end of the incubation period, the emergence and unhatched eggs are assessed. The treated blocks are then cut open to count the surviving or dead larvae inside.

The NF EN 49-2 standard evaluates the effectiveness of products applied to wood by impregnation. After treatment, the test principle and evaluation criteria are similar to those of the NF EN 49-1 standard.
