Mountain Pine Beetle Research Paper

The Boll Weevil is a beetle. A drought is when an area has no rainfall for a long period of time. The Boll Weevil feeds on flowers and lay eggs in the flower buds of cotton. The Boll Weevil came from Mexico to Georgia to destroy the cotton plantation in the 1890s. A Drought came in Georgia and caused destruction on the crops also. Since the crops and cotton were destroyed, farmers could not pay people to pick them. So, many people lost jobs, and banks that loaned money to farms took huge L’s. Also, most working farms fell. The Boll Weevil and the Drought destroyed Georgia’s farms and its crops, including cotton. Since the cotton was gone, the Boll Weevil

Insecticides have been used to try to control the emerald ash borer. However, there are guidelines for the use of these chemicals. There is a per acre use limit which means that all ash trees in the same area can be treated more than once in a year with the same chemical. Before treating an area one should pro-rate the acre use limit to match the size of the treatment area in order to control the concentration of the chemicals being used. Insecticides used against the borer may be soil applied, trunk injected and cover sprays. The soil applied treatment has been tested and has proved to be very inconsistent. Therefore, environmental activists concerned about the use of insecticides moved towards using a trunk injected treatment, but this has too been proven inconsistent in their trials. Cover sprays, however, seem to be providing mediocre results. While this treatment

The government of Canada has decided to implement a 30 year plan, which will cost over 2 billion dollars, it includes using insecticides and traps to eliminate Emerald Ash Borers and further infections in ash trees. Another negative effect is Emerald Ash Borer’s ability to consume white fringe tree, a close relative of ash trees, which is a sign that Emerald Ash Borers might be able to infect different types of tree in the future. Emerald Ash Borer has caused a slowdown in Canada’s forestry industry due to the death of many ash trees, which will mean slower economic growth for Canada, since we rely a lot on forestry products. Emerald Ash Borer has been increasing in population rapidly due to a lack of enough predators. As Emerald Ash Borer continue to threaten our forests, which has provided us with camping grounds, shade, and oxygen for years will be at risk. Ash trees are also an important part in preventing clogged river, streams, and water-treatment plant because of soil slides resulting from rain. Trees normally holds on to the soil to prevent clogged rivers and streams, but with Emerald Ash Borers wiping out million of ash tree and putting billions more at risk, it could disrupt the delicate balance between trees and soil. Researchers expect ash tree mortality rates will have ecological impacts on animals that rely on ash

Because of the large population of ash trees in Ottawa, it would be prohibitively expensive to inject every ash tree on city property. The injection program, therefore, focuses on injecting ash trees that will receive the most benefit. The Current state of Ottawa’s Ash Tree’s is extremely worrying, every other day a tree is needing to be removed and replaced from homeowners front and back yard’s. Trees in Ottawa are very important for maintaining and improving our air quality. When the majority of our ash trees have been destroyed by the Emerald Ash Borer we must have solutions in place as soon as

The ancient forests of the Northeast aren’t the only aspect of the bioregion that’s fate have been at perpetual risk since the early settlement of Europeans. There is no question that forests still dominate the landscape of Northeastern region accounting for “60% of the total land area, and in New England alone, the coverage is 80%”. Still the species that exist within the understory of the forests have undergone an equally dramatic transformation because of human interaction with the land and the harvest of its resources. Some species in the understory of the mixed forests of the Northeast have been driven out of the region, are under intense ecological pressure, are on the brink of extinction, or have already gone extinct in the region. Perhaps one of the most harmful and impactful effects colonization of the Northeast has had on the resources of the land is the introduction of non-native species and diseases into the region. Over time the overall makeup of the forests have changed drastically as an example, “…the American chestnut once made up as much as 25% of the trees in some areas and was economically the most important hardwood in the Eastern forests”. The introduction of chestnut blight at the turn of the century accounts for

Females lay white spherical eggs on the trunk, and produce a yellow viscous material from the ovipositor which is smoothed over into a covering, before fading to white or grey. Larvae exit the egg directly into the plant, never becoming exposed, and so are impervious to sprays. Young larvae are restricted to the cambium, circling the cane 3-4 times in a close spiral, girdling the primocane, and producing gall-like swellings. As larvae grow, they extend feeding deeper into wood and pith, and staightening the spiral and heading usually toward the distal end of the cane (tunnels may extend 15 cm below to 64 cm above the gall). Larvae reach a length of 12 mm, and have a pair of horn-like projections on the posterior end. The larvae are white and legless, with a flattened head (the family is often called flat headed borers). Larvae winter in the cane, and in March create a pupal chamber. The pupa is formed in late April. The pupal period lasts 20-40 days. When the adult leaves the pupal skin, it remains in the tunnel for about 10 days before chewing a D-shaped emergence hole. Adults feed on foliage for several days before beginning oviposition. They are most easily found on the plants on warm sunny days. There is one generation

Eliminating the bronze birch borer from your trees and restoring them to their natural health requires multiple treatment methods. First of all, you need to ensure the health of your tree by watering them regularly: one slow watering every few weeks should be enough. Next, you need to spread at least three-inches of wood chips around the base of the tree to hold in moisture. Most importantly: do not fertilize your trees when they are infested with the bronze birch borer: the extra growths can actually attract more birch borers to your

Many people think that to get rid of them we have to cut down the ash trees but that is not true. Recently in Burnsville, this summer it injected 14 ash trees at City Hall with pesticide to protect them against the emerald ash borer. Deborah McCullough, a professor of entomology and forestry at Michigan State University. Based on her research, she says: “There is no reason for a landscape ash tree to die from emerald ash borer anymore. The treatment is so effective and so much cheaper than removal and replacement that I can’t get a single elected official to weigh in on the side of removing healthy trees because we don’t have to, and that is never popular with the public.” Private ash trees that were not injected are dead, while treated ash trees on city property stand nearby in good health. Michigan and Ohio State research shows that injecting Tree-age “provides at least two years of almost 100 percent control” of larvae, McCullough said. Applying pesticides every two years costs about $250 a tree, while removal and replacement is $700 to $1,200 a tree. The company says the product is a safe, “organic” option. We should try that option instead of cutting down trees. This would help protect the area of great lakes from emerald ash

Emerald Ash Borer (EAB) most likely came to the United States through solid wood shipments from Asia, and has established its habitat in 25 states - including Georgia - and two Canadian provinces. The female lays eggs and the cream-colored larvae chew tunnels through the wood. The adults are shiny green beetles about a half inch in length and burrow through the wood. Symptoms of EAB infestation in a tree include vertical

The earliest known presence of the emerald ash borer in America was in 2002, near Detroit and Windsor, Ontario. Since then, it has widely spread throughout the country. The emerald ash borer is a very well-named pest: its larvae bore deep into ash trees to suck their nutrients and when it emerges as an adult, it is a bright emerald

In 1993 Volkswagen had record low sales but by the end of 1997 the VW brand had sold 137,885 cars. That was an increase of 178% from it’s 1993 slump. It is safe to say that the the ’94 relaunch of VW on the American Market was a success. The “Drivers Wanted” campaign, developed by Arnold Communications, I believe was successful as a result of excellent market research and positioning.

God perfectly designed every animal to be fully capable to live their lives just how the need to. Each animal is way too complex to evolved into another form. To proof this, I will show you some amazing animals that God has created. The European Green Woodpecker's tongue comes from the back of the throat, travels from the back of its head, through its nostril, and out of its mouth. Clearly that is way too complex to be evolved, and evolutionist have no idea how because no other animal has that type of tongue. The Bombardier Beetle manufactures chemicals that makes a explosion to protect itself. There's no way that this bug could evolve, it needs all of its parts their all at once or you don't have the animal. God created this bug was created

Humans have been changing the Western forests' fire system since the settlement by the Europeans and now we are experiencing the consequences of those changes. During the summer of 2002, 6.9 million acres of forests was burnt up in the West (Wildland Fires, 1). This figure is two times the ten year annual average, and it does not look like next summer will be any better (Wildfire Season, 1).

After implementing the FMP, planting and cutting were greatly dropped. Figure 5 shows cutting volume. Harvesting fuelwood in the coppice forest already stopped in 1960’s. Coppice forest is mainly composed of some kinds of oaks, and is regenerated with fresh shoots from the stumps of trees after harvesting fuelwood is done. And both coniferous and broad leafed timber declined around 1990. Planting area followed almost the same trends. After 1995 statistics of harvest volume are not available. The YWB officially asserts that it has made no profits on sales of timber since 1994.
