The emerald ash borer (Agrilus Planipennis) is an invasive insect species that has infected and killed many ash trees across eastern North America. The ash borer was first sighted in Michigan and Ontario in the summer of 2002, and has since spread widely east of the Mississippi. The species, the characteristics of the insect,the amount it has spread over the years, and the effect and damage that it has done in its new habitat have been followed since first discovered in North America. The emerald ash borer originated in eastern Russia, northern China, Japan and Korea. The species most likely came to North America by the use of ash wood for stabilizing heavy cargo loads and also by the packing and crating of products that were being transported overseas. On the insects native land it does not do any damage to the trees that are growing there. In North America the borer has killed tens of millions of trees and is still killing more. “The adult beetle is dark metallic green in color, 1/2 inch-long and 1/8 inch wide.”(Usborne). The beetle is about the size of a penny but its size doesn’t stop it from doing major damage to North America’s ash trees. …show more content…
The female lays her eggs on the tree, and when they hatch the larvae drills itself under the bark where the trees nutrients are stored. The larvae then tunnels its way around the inside of the tree to get its necessary nutrients. the article"State: Invasive beetle in 6 counties." explains it as “The eggs hatch and the larvae bore into the bark to the fluid- conducting vessels underneath. The larvae feed and develop, cutting off the flow of nutrients and, eventually killing the tree.” This is the problem that nothern America is facing, which is proving difficult to
The larvae of this species feed and develop exclusively on the seed of legumes hence the name bean beetle. The adults
This causes troubles including starvation, freezing to death, or going outside before the winter is over. The fungus can usually be seen on the noses of bats as well as parts of their body that are hairless, such their wings. The fungus can not always be seen.
Only the larva of this insect can actually eat cloth, the adults just don 't have the mandibles to do so. They have four life stages, the egg, larva, pupa and adult. The adults only live two to four weeks. The larva are attracted to animal products that contain keratin. This is a fibrous protein found in hair and skin.
Comparison and Contrast Essay Virgina Woolf and Annie Dillard both wrote an essay entitled, “The Death of the Moth.” Woolf wrote her essay in 1942. During this time, she was a female writer struggling with mental illness and the constraints placed on her by society. In her essay, Woolf uses a moth to symbolize her own life. 32 years later, Dillard wrote her essay.
The fungus is called “chytrid” and the have spread it across Southwest America. Biologists around the world have held bullfrogs as the main spread of this fungus. They said its being carried farther as bullfrog keep invading. They don't believe in them stopping as long as the older adult bullfrogs continue to try to eat the younger ones they will continue to run away from them. They have known other option and they will need to keep spreading if we don't try to stop
Though Gray Wolves are only one animal in the environment they have an impact on other animal populations and resources. By hunting elk, Gray Wolves keep elk herds moving, which prevents them from eating trees, like willow saplings. This helps beaver populations because willow trees are a source of food for beavers. Also, beavers build dams out of the trees to create watering holes for other animals and streams for more willows and other trees to grow

Michael Boydstun ENVS 101-1998 Environmental Impact of deforestation In the Pacific Northwest The first people to explore the wilderness in what is now Oregon and Washington documented beautiful forests of mesmerizingly large trees as far as the eye can see. The explorer’s initial reports brought in people who came to make a profit off the forest and the vast amounts of lumber it could provide. Lumber mills were built before the area was even added to the union. The environmental footprint started out small, but the lack of regulation, lack of enforcement of the existing regulations, and an increase in technology quickly created a large environmental battle over the whole region.
Most notably, in the fall, you 'll see a colorful blanket of spent leaves, covering everything they land on. If they do this on your lawn, you may see a problem. In the forest, those leaves are far from a problem. They 're a necessary and welcome part of the ecosystem. Mother Nature doesn 't do anything by accident.
Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
No one knew why. After a few months they found out it was called yellow fever because of the mosquitoes that were carrying the disease. The people decided to take action. They found out that they die in cold weather. So they got cold oil or water and sprayed it in all of the grass dry or wet and they did that every day for about a week and eventuly they killed every last one of them.
This species was only observed during the fresh and bloated stage of decomposition. Hy. Violacea is considered as forensically important fly and had been reported in literatures as being the first colonizers on animal carcasses placed outdoors in estates and forested areas[1,3,10].The first study on the larval growth parameter and growth rate of this blow fly species was reported by Chen in 2008[11].The larvae of Hy.violacea were recovered from a corpse for the first time by Ahmad Firdaus in 2010 [12].The absence of this species from monkey carcass placed in the campus shrub area is expected as Hy.violaceais a forested
At the conclusion of each of the three trials, the number of caterpillars that showed peck marks was tallied. The average of the three trials revealed that 0.67 out of 8 patterned caterpillars had been pecked and 2.67 out of 8 of the solid colored caterpillars showed signs of avian predation (Figure 1). The average rate of avian predation for the three trials was 8.3% for the patterned caterpillars and 33.3% for the solid colored caterpillars. The number of patterned caterpillars pecked was less than the number of solid colored caterpillars pecked for all three trials. It was observed that there were no adhesive issues, weather related damage, or interference from tree
The Beetle, an 1897 novel by Richard Marsh, takes place in the dark and supernatural country of Egypt, where said creature of horror is believed to change its form at will, and use its hypnotic powers to prey upon young middle-class English people. The novel appears to, more often than not, deal with society’s anxiety surrounding the turn of the century. Marsh analyses the opposing views of sexuality and femininity through the exchange of sexual manipulation in the novel. By numerous means of sexually influenced interferences, and the degenerate figure of the colonized, The Beetle builds a sort of parallel between the practices of the British Empire, allowing the British characters to see their individual wrongdoings in a horrific other form.
Ringworm is the most common form of fungal infection in the world. It is an extremely contagious skin infection. There was not even any documentation of this until the 1920 's. It is theorized that American soldiers brought it to the United States after World War I from Europe. When you hear the term Ringworm, you might think that an actual worm is involved with the infection, but this is not the case. Ringworm is a fungal infection that sometimes leaves a circle-like appearance.
