Insects and mites
Insects and mites can damage the leaves, branches, roots, or stems of trees, either directly by feeding on these structures or indirectly by acting as vectors transmitting diseases. The damage can range from relatively minor issues, such as a negative affect on plant appearance, to more severe issues, including reduced tree growth and even tree death. Insects and mites, however, also play important ecological roles in forests by decomposing and recycling organic matter and nutrients, pollinating flowers, and serving as food sources for wildlife. Many insects and mites, acting as natural enemies (i.e., predators, parasitoids, or parasites) of pests, play a beneficial role in reducing pest populations. The study of insects is referred to as entomology, while the study of mites and ticks is called acarology. Insects and mites are classified according to a taxonomic system.
