The pests in wood They are both aesthetic and functional problem (for structural beams). SinceL'Artisan, A service of preventive and curative treatments is offered wood to identify and control these pests. Furniture, chairs, tables and beams are the most common places where we found this plague. The xilófagos, Insects that eat wood, They are responsible for these problems, but the most common and known are termites Y woodworm.
Termites usually do not live in temperate climates. Woodworm, most common in this area, they are the common name given to the larvae of several species of beetles that perforate wood in building and galleries which damaged.
The first of these diseases is rot, which appears through the disintegration of the chemical elements forming part of the sap. The causative agents are certain types of fungus. We can distinguish between white rot and blue.
- White, which is dry, has this name because it appears as a mass of very light, almost white. It arises, especially when this material has been in contact with moisture.
- Blue springs in trees that are cut, but not immediately transform wood and bark are maintained for a long time. It is so called because in the pine whiteness azulea intensely, although other species acquires a different color (on the oak turns brown, the red spruce, depends on the specimen).
When the disease is advanced can give wood use, it provided that sierre immediately and is installed in a cool, dry place. To prevent putrefaction should give it a coat of varnish with linseed oil or tar. In order to get hard boards and take greater weight, you can be impregnated with creosote or metal salts such as copper sulfate.
Another disease that can have this material is mildewDue to the attack suffering from fungi. If they spread quickly, they can cause their total destruction. The we identified by the appearance of eruptions of white on the surface. They originate mainly in damp places. If you are not able to recognize them safely, you can check giving a shock, because when attacked by these agents, the sound of the wood is turned off.
The way to prevent mold is situate wood in a place where fungi can not have a good livelihood. If you have SLE, one solution may be to apply a jet of hot air (over 60), then removing the damaged part and giving finally a layer of cement.
When we talk about woodworm we refer not only to a defect but also means that insects have already deposited their larvae in the trunk. Forman galleries that are often built unvented and, therefore, may not see them, but I do hear the noise produced to gnaw. The most common way to alleviate it is injecting into the strong acids galleries finish them. If you want to prevent their occurrence, you can do by giving them a coat of varnish.
Other agents are destructive termites. Although not very common in Spain, its pests are very dangerous in other countries because it can destroy a wooden house in a few months. Usually act on old wood and its main objective is to eat its components. To end them, we can use specific insecticides products.
Finally, we must not forget that other little annoyances can make wood a useless material: the case of beetles and called anobios moths.
Termites digest cellulose with the help of microorganisms living in symbiosis within your digestive tract. Termites have economic importance as pests in wood, paper and cardboard structures, works of art and stored products. There are about 1,900 species of termites. They live in colonies that may have more than 2 million people. In each colony, the queen is the only one that lays eggs. Most of these insects lack wings but during the time of reproduction some develop these organs and leave the group to form own colonies. Species that have been detected on the coast of the Iberian Peninsula are:
- Subterranean Termite, Reticulitermes spp. - In the Mediterranean coast seems predominant species R. banyulensis
- In the rest of the peninsula, grassei R. and R. Santonensis, dry wood termites, Kalotermes flavicollis and Cryptotermes brevis
It is a cascarudo whose larva reaches up to 30 mm long, this being the only stage of life eating wood. It can remain as such for 3 to 10 years (can be over 10 years depending on the temperature, humidity and nutrients), during which lives and feeds into the woody parts (beams, ridges and machimbre ceilings, columns, etc). They originate elliptical galleries that fill with a mixture of sawdust and excrement. Reaching its peak, these larvae spend the pupal stage, in very close to the wood surface area, thus remaining about 3 weeks, after which they become adults.
Adults emerging from the timber to reproduce, leaving holes elliptical section 7 to 10 mm larger diameter. These are 20 mm in length, have a black or dark gray brown and possess long antennae characteristics of the family to which they belong. The fertilized female oviposits 200 eggs in batches of 2 to 8 eggs for 12 days in cracks and fissures of the wood. These hatch approximately 2 weeks.
