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
Frass (termite droppings): Subterranean termites push out their waste, known as frass, through small holes in the infested wood. It looks like tiny pellets and can accumulate below the infested area.
The bark beetle's pheromones, including kairomones, can attract other insects. [16] The pheromones distinguished as kairomones are hormones, pheromones, or allomones of bark beetles, which in turn are used as a locator by insects that are attracted by it, such as flies, which may intend to harm the bark beetle itself.

Termites are a group of detritophagous eusocial insects which consume a variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus.They are distinguished by their moniliform antennae and the soft-bodied and often unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants, being more closely related to ...
The third type of clerid beetles is the "nest robbing species" which live in shrubbery and in trees. Unlike the tree living species, these species do not actually burrow into the bark. Nest robbing species typically hunt termite, bee, and wasp larvae, and one particular species has been noted to prey primarily on grasshopper egg masses. [4]
This bark beetle feeds on the developing bark on and around the root crowns of tree seedlings, [1] especially the phloem. [3] It also infests stumps , logs, and fallen trees. It prefers pines, and is a widespread pest of wild and cultivated Monterey pines ( Pinus radiata ) in particular. [ 1 ]
The bark of Pinus thunbergii is made up of countless shiny layers. Bark is the outermost layer of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. [1] It overlays the wood and consists of the inner bark and the outer ...
Species closely related to Tomicus piniperda include Tomicus minor (lesser pine shoot beetle), with a similar distribution but ecologically separated, using standing dead pines and with its breeding galleries across the grain, not parallel to it; [2] Tomicus destruens in the Mediterranean region, which differs in details of ecology, infesting primarily stone pine P. pinea and maritime pine P ...
