POWDERPOST BEETLE (Lyctus Bruneus) Found world-wide, this insect attacks the sapwood of hardwoods such as Oak, Elm, Ash and Eucalypt, although woods with low starch content such as Beach and Birch are generally immune. Woods such as Cherry and Lime are also considered immune, as their pore size is too small to accommodate the egg laying requirements of the female. Softwoods are not affected. Damage usually starts prior to the delivery of timbers to the site and can continue after being incorporated into the building. Common in products manufactured from susceptible timber such as furniture, roof rafters and flooring. Damage may be missed in early stages. In later stages the damaged timber may be reduced to a powdered mass inside a thin intact skin of wood. Adult insects are 4-7mm long and are reddish brown to black in colour. They are flattened and elongated, compared to the "roundish" shape of the furniture beetle. The flight holes of emerging adults are usually 1.5-2.0mm in diameter. The larva is pale cream in colour with light brown oval spots on either side of the body. It has three pairs of legs and is up to 6mm in length. May be present in affected timbers for up to 2 years. Tunnels 1.5-2.0mm in diameter are of random orientation mostly parallel to the grain. Bore dust is cream in colour, fine and talc like and may accumulate in piles under flight holes. Easily shaken out of tunnels. If you want to order a Pre-Purchase Inspection please print a Pre Inspection Agreement form and fax it to our office. |
