Scolytus is a genus of bark beetles known for their role in the ecosystem as decomposers. These small insects typically infest trees, particularly conifers, by boring into the bark to lay their eggs. The larvae feed on the inner bark and wood, which can lead to tree damage or death. Some species of Scolytus are considered pests, especially in forestry and agriculture, as they can cause significant economic losses. Effective management strategies often include monitoring tree health and using insecticides when necessary to control their populations and protect valuable timber resources.
