The term "gribble" was originally assigned to the wood-boring species, especially the first species described from Norway by Jens Rathke in 1799, Limnoria lignorum. The Limnoriidae are now known to include seaweed and seagrass borers, as well as wood borers. Those gribbles able to bore into living marine plants are thought to have evolved from ...
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Limnoria lignorum is a wood borer and in favourable conditions can be present in large numbers, with densities of as many as four hundred individuals per 1 in 3 (16.4 cm 3) of wood. The isopods are very small and the damage is at first confined to near the surface of the wood.
These predators feed on the bamboo borers eggs, larvae, pupae, and sometimes adults. However, even if natural enemies of the borer have the potential to cause high mortality rates in borer population, natural enemies cannot be relied upon as an effective control method. [3] Physical control relates to bamboo wood treatment post felling.
The common furniture beetle or common house borer (Anobium punctatum) is a woodboring beetle originally from Europe [1] but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult Anobium punctatum measure 2.7–4.5 millimetres (0.11–0.18 in) in length.
