Bark beetle

a particular mountain in Yellowstone contains a large population of white bark pine trees and about twenty grizzly bears. Over about twenty years, average temperatures get significantly warmer due to pollution and climate change. As modeled by the diagram, warmer temperatures lead to an increase in the population of white bark pine infesting beetles. An increase in the beetles overwhelms the defense systems of the white bark pine trees, and they are completely wiped out from the mountain in…

They live just beneath the bark of the tree and move in a zig-zig pattern along the tree. As travels under the bark and above the thick layer of wood, it lives a silent and dark world. It takes in the nutrients it needs from the tree. While tunneling through tree the larva is causing damage to the tree by feeding on the thin layer of tissue under the trees bark called the cambium. After a few weeks of this it metamorphoses into an adult beetle. The beetle then drills or bores its way out of the…

First of all, the reading passage claims that the decline of the cedar trees is due to the infestation with the cedar bark beetle, since the larva can eat the tree wood. However, the professor counters this and explains that the beetle can’t infest the healthy tree. The healthy trees have powerful chemicals, which can harm the insects. Moreover, the professor points out that the beetles attack the sick and unhealthy trees which will die by any…

cope with them. One of the most dangerous invasive species is the Asian Longhorned Beetle, which infests a variety of hardwood trees in North America and Northeastern Asia. The Asian Longhorned Beetle originates from China and Korea, but was first discovered in the United States on Long Island in 1996. This Beetle spends its most destructive period when it’s in its larval stage, where it burrows deep within the bark of a tree and feeds on the food…

Head The lady beetles head houses the eyes, mouth and antennae. Antennae The antennae works as the lady beetles sensor organ, the function is to aid the eyes for locations, tasting and smelling predators and prey. Eyes The lady beetle has two simple structured eyes which is why they rely so heavily on their antennas. Mouth The lady beetles mouth is made for chewing small insects during the larvae and adult stages. Abdomen The abdomen houses all the lady beetles internal organs, digestive…

Ash Borer, or EAB. The adult beetles do little harm to the tree by just eating their foliage, but their larvae burrow beneath the bark of the tree and restrict the tree’s ability to transport nutrients and water. The process takes anywhere from 1-5 years and the infestation is usually widespread in an area. Humans are the main cause of the spread of EAB, and it is very important to be educated on the issue to help preserve our ash…

The Asian longhorn beetle (anoplophora glabripennis), the Two Spotted Oak Buprestid (Agrilus Biguttatus) and the large pine weevil (hylobius abietis) and Their Relationship to Forests in the United Kingdom Miranda Sanderlin Summary Invasive species of beetle threaten forests in the United Kingdom every year with increasing impact. These beetles cause costly damage, both environmentally and ecologically. The Asian longhorn beetle (anoplophora glabripennis), the Two Spotted Oak Buprestid…

The boneseed leaf roller moth (Tortrix s.l. sp. chrysanthemoides) is a month in South America that was released in several different locations (New Zealand, Australia) to control the population of the boneseed plant (Chrysanthemoides monilifera ssp.monilifera). The bonseed plant is a destructive plant that overtakes and damages native plants. The plant is thick with daisy like yellow flowers, leathery leaves and black clustered fruit. This plant produces large amounts off seeds that quickly over…

giant Sequoia is the world’s largest tree it is native to California, when the tree is mature its bark is a red/ brownish colour. The physical characteristics of the giant Sequoia include, its ability to resist forest fires due to its extraordinarily thick bark which can grow to 6 meters wide, fire is a huge reason young giant Sequoia trees die. The bark of the tree is also resistant to fungi and wood beetles. The tree can resist windfall and its wood does not rot. Although fire can kill young…
