Generally, forests are considered to be essential to animals other than their commonly known benefits to the humans. Usually, they stabilize and support the ecosystems, they are an important part in carbon cycle, and also support the livelihoods among many other benefits. Due to their important roles to the ecosystems, it become essential for forest health and entomologic threats to be monitored and dealt with, so as to protect the 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 natural and the non-natural stress on forests include entomologic threats posed by insects. Insects apart from being beneficial, they can cause adverse effects to forests. Their impact usually results in dwindled and unhealthy or alternatively very healthy forests. The benefits presented by insects to trees and forests are various.
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.
Large native insect infestations also support the health of forests by effectively eliminating the sick and unhealthy trees. The elimination of the sick, as well as unhealthy trees means that only the trees that are genetically superior and free of any diseases will reproduce to form the new forestlands. This leads to the development of healthy trees translating to healthy forests.
On the contrary, insects by eliminating the sick and unhealthy trees help reducing competition among the trees. This makes ecosystems thrive and become more productive. The destruction and elimination of sick, unhealthy as well as aged trees by insects aid in lessening unnecessary competition in getting nutrients apart from also increasing the supply of nutrients to the trees left behind. Insects particularly native ones as well assist in plant pollination. For instance, cross-pollination aided by insects will always guarantee the thriving of genetically superior trees.
Nevertheless, insects also result in other entomologic dangers to the existence and life of forests. First, insect invasions often reduce forest area by attacking the unhealthy and healthy trees. However, this can be seen as temporary since trees always regrow. The alien insects and disease pests are also threats to forests because they destroy trees, which result in challenges controlling the population. Again, the alien insects are also difficult to predict their trend.
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.
