Brown powder-post beetle (Lyctus brunneus)


The brown powder-post beetle (Lyctus brunneus) is a species that has been accidentally imported in tropical wood. The adult beetle is up to 7 mm long, slender and with a brown-red colouring. The larvae are up to 6 mm long and require wood types rich in starch to develop (e.g. limba, obeche, oak, nutwood). Maple, red beech, heartwood and coniferous wood are hardly affected or not at all. The exit holes of the adult beetles are 0.8 to 1.5 mm in diameter. Closely related species include the European lyctus beetle (Lyctus linearis) and southern lyctus beetle (Lyctus planicollis).


The brown powder-post beetle occurs mainly in imported wood (e.g. in souvenirs and furniture). Damage results from the larval feeding channels inside the wood and the exit holes of the adult beetles on its surface. The damage is the same as with the woodworms, the difference being that the wood is destroyed more quickly and completely.
