Sample Essay on The Mountain Pine Beetle

Introduction

The mountain pine beetle is one of the species of the bark beetle. It is native to the forests which are located in western parts of North America, Mexico, and central parts of British Columbia. This creature has a hard black exoskeleton, with an estimated length of five millimeters. It is believed that the mountain pine beetle does not come out throughout the year; the reason being the effect of cold spells. Another aspect is that beetle proliferation is only encouraged during the longer breeding season. The mountain pine beetle affects pine trees by laying eggs under the bark of these trees. The beetles attack the pine tree by introducing blue stain fungus into the sapwood, stopping the tree from repelling the beetles. The fungus that the beetle introduces into the tree also blocks the circulation of water and nutrients within the tree. The tree dies after the circulation of nutrients and water is blocked. After the beetles attack a tree, they move to a different tree and attack it (Maher,et al, 2015).

There have been high rates of mountain pine beetle outbreak recently compared to the previous years. It has affected almost forty million acres of forest. According to researchers, the increase has been caused by the climatic changes that support the life cycle of the beetle. Several techniques can be applied to manage the attacks. They include luring beetles into a trap that have a synthetic hormone that produces the scent of a female beetle, and after that, their destruction gets contained in one area. Another option is destroying the infested trees to control the spread; this can be done through burning the infested areas before the beetles attack new trees of a forest. Lastly, the beetles can be controlled through the use of pesticides (Lehman,et al, 2016).
