The xylophagous insects, or insects that feed on wood, play a fundamental role in nature. However, in rural or urban environments these animals can cause serious problems.
From Ecologista Verde we invite you to continue reading to learn about this topic and discover 7 insects that eat wood, their characteristics, names and photos.
What are xylophagous insects - characteristics
It is called "xylophages" To them organisms that are capable of digesting wood so that they can take advantage of their nutrients. For example, there are other animals that can gnaw or take advantage of wood, but they do not give it a food use.
These insects have different adaptations that allow them to take advantage of a material that, in general, is not digestible. It must be taken into account that wood has large amounts of cellulose and lignin, both materials with very regular bonds and of strong consistency, from which it is difficult to take advantage of energy. Thus, these insects have mouthparts adapted to the wear of this material, and also live in symbiosis with bacteria that lodge in their digestive systems and allow them to digest it.
Termites
Termites They are divided into three different ecological groups:
- Wetwood termites: As their name suggests, they live in humid woods, which have assimilated the humidity of the surrounding environment. They are common, for example, in coniferous forests, or small wooden piers.
- Drywood termites: They live in dry wood, both in natural environments and in urban areas. They can withstand long periods without water, and are quite dangerous for construction. Especially important are those wooden constructions with historical-heritage value.
- Subterranean termites: They live under constructions, and can seriously damage their foundations. They can even become pests.
Woodworms
These insects feed on the wood in their larva stage. They produce a characteristic sawdust called "quera". Woodworm it is very rare in nature; However, it can cause great damage in anthropic or human environments, since the larvae rarely settle on living wood, preferring dry and warm environments, such as those found in furniture.
Hylotrupes bajulus or borer bug
like the woodworm, the Hylotrupes bajulus (also know as "big woodworm"due to the large size of the adults, or"wood moth") is a beetle that lays its eggs in the wood, taking advantage of small fissures or other natural holes that can serve as protection when hatching occurs. Its larvae are whitish in color and feed on wood at birth, also giving rise to a characteristic dusty sawdust. This wear activity can become audible when in silence. Unlike woodworm, the holes left by adults are not circular, but rather have irregular edges.
Anobium punctatum or wood beetle
The wood beetle It is a brown or reddish beetle. As in the two previous cases, the females lay their eggs in the natural cavities of the wood, generally dry wood. When the larvae hatch, they begin to excavate galleries. This pest is characterized by the long periods of time it covers: the larvae can remain for up to more than 3 years, digging galleries and feeding on the wood. The pupal stage of the Anobium punctatum it is completed near the surface of the wood, since adults do not have a specialized oral appliance that allows this excavation.
Wood wasps or Urocerus gigas
The wood waspsUrocerus gigas) they belong to the family Siricidae, a subdivision of Hymenoptera. The females deposit their eggs in the wood of the trees and the larvae are those that excavate galleries. Adults have a more or less cylindrical body and are usually dark (blue or brown), with some areas of yellow pigmentation. They have in common with him Anobium punctatum the large one larva stage, which may be more than three years old, and that the pupae are located close to the surface.
Wood-eating insects: how to control them ecologically
Xylophages They are present in various ecosystems (such as coniferous forests). As we have seen, many species are capable of feeding on wood only in their larval stage; This is a strategy that many species (including mammals) present, in which the juvenile phase has a different diet than the adult one in order to avoid competition between them, and to cover more available resources.
In any case, whether it is the adults or the larvae, these insects play an important role in ecosystems: if we analyze the food web, they are usually classified as decomposing organisms, since they help a matter that is inert in principle (since it cannot be used by most organisms) can be reintegrated into the matter cycle. In addition, both larvae and adults serve as food for other animals.
However, in rural or urban settings they can reach become pests and cause serious damage to different infrastructures. The best way to protect our wooden structures is to prevent the laying of eggs or the arrival of termites: keeping the wood clean, without cracks and renewing the protective layers is a good way.
Once we find the problem, we can try to apply green solutions to a pest of wood-eating insects. The most common is to use biologic control, that is, to place nearby populations of successful natural enemies, such as wasps or parasitic nematodes. Each of the species will have a series of these natural enemies, of which we can take advantage of.
