Tanbark borer
…is the tanbark borer with the Latin name Phymatodes testaceus. The tanbark borer belongs to the genus of wooden borer. The members of this genus have long, curved feeler horns reminiscent of goat horn. Appearance When the tanbark borer is fully grown, it is between 10 and 15 millimeters long. Its breast usually has an orange color, while its coverts are characterized by a blue color. However, there are also variants of the tanbark borer, where the…
The Borer snout beetle
…ll as conifers. The small larvae usually take a year to develop into adult borer snout beetles, and the borer snout beetle can hatch all year round. When the adult beetles are ready to leave the tree, it does so through small fly holes that have a diameter of 1 to 2 millimeters. These fly holes are oval and have a slightly irregular outline. They leave passages with borer flour, which is a fine and dusting material that consists, among other thing…
The lesser grain borer
The lesser grain borer Fig. 5.41. Lesser grain borer with larva that lives inside the kernel. Latin: Rhyzopertha dominica. 2 – 3 mm long, reddish-brown to black-brown beetle. The prothorax is large and rounded in front like a hood, which on the top and in the front is covered with small lumps. The lumps help when the beetle drills. Head with mouth parts is on the underside of the prothorax and is not seen from the back. Feelers are 10-jointed and…
Lesser grain borer
…Lesser grain borer (Latin: Rhizopertha dominica) This species belongs to the family Bostrychidae, a group of tropical beetles which includes several wood-boring species (p. 128). It can be a very serious pest of stored rice and grain in warm regions (see p. 93). Lesser grain borer in corn…
Fan-bearing wood-borer
…Fan-bearing wood-borer ( Latin: Ptilinus pectinicornis ) This species, which is not as common as the other wood-boring beetles, mainly infests deciduous trees, e.g. beech, birch, oak. It is easily recognizable by the large, comb-like antennae. Unlike the other wood-borers here the adult beetle also gnaws timber. The wood dust is very fine and similar to that produced by the powder post beetles….
Soft wood boring beetle
…Biology and behavior The soft wood boring beetle belongs to the family of borer beetles (Anobiidae) under the family soft borer beetle (Ernobiinae). Conifers are, as described, the preferred place for the soft wood boring beetle to settle. The soft wood boring beetle seeks out weakened and felled trees for its purpose. And as long as the bark is still intact and not dried out, it is an obvious destination for the borer beetle. The female lays her…
Deathwatch beetle
…watch beetle – with the Latin name Xestobium rufovillosum – is the largest borer beetle in this country. The deathwatch beetle can make a special sound that in ancient times has given it the name “death clocks”. Appearance Although the deathwatch beetle is the largest borer beetle that lives in Denmark, it is still quite modest in its size. An adult beetle is only between 6 and 9 millimeters long. The beetle has a brown color, but around the body…

…ut it must not be so rotten as to be falling apart. The fly holes of wharf borer beetles are irregular and oval. They can be confused with the house longhorn, but the wharf borer beetles only grow in moist wood, unlike the house longhorn beetles. When seen in a house this beetle may have come in from outside, having emerged from ships’ timber or wharves, and it also thrives in piling and in structural timber in damp cellars. It is not uncommon for…

This way you are sure that you are fighting the parasitic wasps properly. If the number of parasitic wasps is due to borer beetle infestation, you must fight the borer beetle and not the parasitic wasp. As the beetle is controlled and removed from the area, the parasitic wasps will us…

Wharfborer exit-holes in timber Wharfborer The exit-holes are irregular, oval or circular, up to 6 mm in diameter, and they occur mainly in softwood. They may be confused with those made by the house longhorn beetle but the present species only attacks damp timber, and it is typical that the larval tunnels contain numerous pieces of wood fibre ( see p. 141).

Gnawings on packagings are due to more common pests that have eaten their way from the inside out. Moth larvae will often gnaw their way out of the package in which they lived before they pupate. Newly hatched drugstore beetles can chew through the packagin…
Bread beetle
Latin: Stegobium paniceum In the family of borer beetles (Anobiidae) is the bread beetle found, which also goes by the Latin name Stegobium paniceum. But unlike many other members of the genus, the bread beetle cannot live in wood. Instead, it has a taste for starchy foods, hence the name. When the beetle larvae hatch, they leave circular holes in the material they have lived in. And these holes are confusingly like the holes in a tree that has h…

The eggs are never deposited on smooth surfaces but in crevices, on the end grain, or on unplaned timber, and very often in old exit-holes. The eggs hatch after 3-4 weeks, and the tiny larvae start immediately to gnaw into the timber. They leave the un- digested parts of the timber in the tunnels in the form…

This beetle is very common and can be found practically everywhere that timber with the bark still on is used in house construction. The damage done is purely superficial and will not affect the mechanical strength. On the other hand, if such timber is covered with sheets of any kind the emerging beetles will gnaw their wa…
