Forests are generally considered to be crucial to animals apart from their predominantly known benefits to humans. They support and stabilize ecosystems, form a key part of the carbon cycle and support livelihoods among various other benefits. Because of the crucial roles that forests play to the ecosystems it is always key that forest health and entomologic threats are monitored and handled to protect these ecosystems.
Currently, vast forestlands remain under pressure from pollution, overexploitation, agricultural practice expansion, and intensification as well as population pressure. Combined with the effects of climate change, forestlands are even threatened further with threats posed by insects. All these are factors that influence the health of the forests and thus impairing its ability to maintain the ecosystems.
Among the different natural and the non-natural pressures faced by the forests one is the entomologic threats. Usually, insects are beneficial and destructive to the forests as well. Their impact result in a healthy, dwindled or unhealthy forest. First, insects usually offer several benefits to the forests, as well as keeping them healthy.
The first benefit is that some of the native insects are usually beneficial in maintaining and reducing aging of the trees. As a result, the forests become more productive and are able to support a healthy ecosystem. When there is large infestation by insects regularly, the forests are renewed. The old trees are usually destroyed which result in releasing the nutrients stored in them and utilized to support the new trees.
Native insect infestations as well support the development of healthy forests by eliminating any sick or unhealthy tree. Commonly the elimination of the unhealthy or sick trees implies that only genetically superior trees and those free of diseases reproduce and form new healthy forestlands. This development of healthy forests can then support healthy ecosystems.
On the other hand, insects usually aid in eliminating competition between trees hence making ecosystems to be more productive. By destroying and eliminating the sick, aged as well as the unhealthy trees, insects will reduce unnecessary competition for nutrients and, on the other hand, increase the nutrient supply to the residual trees. Insects especially the native ones also aid in pollination of trees. Cross-pollination particularly aided by the insects ensure that only genetically superior trees will thrive.
However, insects also present various entomologic threats to the life and existence of forests. Insect invasions usually reduce the forest areas by attacking both healthy and unhealthy trees. Nevertheless, this may be considered temporary because trees can always regrow. Alien insect, as well as disease pests, on the other hand, are a threat to forests since they will destroy trees and present difficulties of controlling their populations. Worse still alien insects present difficulties in predicting their trends.
Alien insects usually spread rapidly with the consequence being a trail of vast and extensive damages to trees. This is usually a threat in places where the insects that are invading the forests and causing disease have no existent natural enemies that aid in keeping their populations in check. The other instance, trees, and other organisms have no natural way to resist the invading insects.
