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
Woodboring beetle. The term woodboring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous). [1] In the woodworking industry, larval stages of some are sometimes referred to as woodworms. The three most species-rich families of woodboring beetles are longhorn beetles ...
Binomial name. Monochamus scutellatus. (Say, 1824) Subspecies. M. s. oregonensis. M. s. scutellatus. Monochamus scutellatus, commonly known as the white-spotted sawyer or spruce sawyer or spruce bug or a hair-eater, [1] is a common wood-boring beetle found throughout North America. [2] It is a species native to North America.
Common names include pine sawyer, western pine sawyer, spined woodborer, and ponderosa pine borer. [2] A taxonomic synonym is Ergates spiculatus. [2] This beetle species develops on fallen ponderosa pines and Douglas firs. [3] T. spiculatus is the largest species of wood boring beetle in Colorado. [3]
The pine wood nematode Bursaphalenchus xylophilous is transmitted by several Monochamus species, and its life cycle is tied with that of its vector. [6] When nematode-infested adult Monochamus feed on healthy trees, they create wounds that allow nematodes to enter. In a susceptible host tree, nematodes breed in the xylem and eventually kill the ...
Pholadoidea. Family: Teredinidae. Rafinesque, 1815. Genera. See text. The shipworms, also called Teredo worms or simply Teredo (from Ancient Greek τερηδών (terēdṓn) 'wood-worm', via Latin terēdō), are marine bivalve molluscs in the family Teredinidae, a group of saltwater clams with long, soft, naked bodies.
Teredo navalis has an elongated, reddish, wormlike body which is completely enclosed in a tunnel it has made in floating or submerged timber. At the front end of the animal are two triangular, calcareous plates. These are up to 2 cm ( in) long and correspond to the valves of other bivalve molluscs. They are white, with a covering of pale brown ...
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. The tunnels are about 1 mm (0.04 in) in diameter and usually follow ...
