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
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.
A gribble /ˈgɹɪbəl/ (or gribble worm [2]) is any of about 56 species of marine isopod from the family Limnoriidae. They are mostly pale white and small (1–4 millimetres or 0.04–0.16 inches long) crustaceans , although Limnoria stephenseni from subantarctic waters can reach 10 mm (0.4 in).
Wood-boring insects can degrade the wood aesthetically by boring holes, and also indirectly as vectors for fungi and nematodes which can cause structural damage. [ 5 ] Allison et al. [ 11 ] extrapolated information from one mill in southern British Columbia to suggest that wood-boring insects could cause an annual loss of US$43.6 million per ...
Some such larvae exhibit a superficial resemblance to worms and are the likely inspiration for the term, though they are not true worms. In other cases, termites , carpenter ants , and woodboring beetles will first infest wooden bookshelves and later feed on books placed upon the shelves, attracted by the wood-pulp paper used in most commercial ...
A true weevil. The Curculionidae are a family of weevils, commonly called snout beetles or true weevils.They are one of the largest animal families with 6,800 genera and 83,000 [1] species described worldwide.
Bark beetles enter trees by boring holes in the bark of the tree, sometimes using the lenticels, or the pores plants use for gas exchange, to pass through the bark of the tree. [3] As the larvae consume the inner tissues of the tree, they often consume enough of the phloem to girdle the tree, cutting off the spread of water and nutrients.
The mycophagous phase of the life cycle takes place in dead or dying wood, where the nematodes live and feed upon fungi, rather than the wood itself. The nematode cannot travel outside of the wood independently; it must be transported by an insect vector. B. xylophilus has the shortest life cycle of any known parasitic nematode. In laboratory ...
