Forests are carbon sinks, they absorb carbon dioxide, a major greenhouse gas, from the atmosphere through photosynthesis and store it in plant biomass and soils belowground. When the trees die, they stop absorbing and storing carbon dioxide, and as they decompose, they release some of the stored carbon dioxide back into the atmosphere (Suzuki & Moola, 2008). The mountain pine beetle (Aendroctonus ponderosae) is a primary agent of forest disturbance, a higher number of outbreaks occur due to favorable forest age and climate patterns (Progar et al., 2014). The mountain pine beetle (MPB) starts its attack when the female finds a pine tree (usually lodgepole) that is at least 80 years old. Upon finding the tree the female bores into it, while releasing a pheromone that attracts the male beetles. When the males arrive they, also release more pheromones to attract more females. The tree tries to defend its self by secreting a toxic resin. But the beetles carry spores of a blue-stain fungus in their mouths which they release as they bore into the tree, the fungus prevents the tree from transporting nutrients and water. The beetles lay eggs under the tree’s bark, and when the larvae hatch, they feed on the blue fungus until they are mature enough to leave the now dead tree (Aukema et al., 2006). …show more content…
The MPB outbreak has resulted in a cumulative total of 710 million cubic metres of dead pine in British Columbia’s forests (Facts About B.C.'s Mountian Pine Beetle,
The red necked cane borer, Agrilus ruficollis (F.), is a buprestid beetle that infests wild and cultivated blackberries and raspberries in the eastern states from Canada to the Gulf of Mexico. Adults are about 6-7 mm (1/4 inch) long, with an iridescent coppery pronotum. A related species, Agrilus rubicola, may occur concurrently. This species is uniform in color, ranging from copper-colored to iridescent green. On galled plants, there is less live vegetative growth and more dead wood. There is often reduced berry size and number, as well as vegetative growth with increasing number of galls per plant. Affected canes may not produce fruit. Canes weakened by galls are more subject to winter injury.
The Emerald Ash Borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash. The emerald ash borer has already killed millions of trees in North America and is on track to kill many more. Emerald Ash Borer was first discovered in North America in 2002. It is thought to have been shipped to Canada in untreated wooden packaging materials. The range of Emerald Ash Borer in Ontario is rapidly expanding through the movement of infested materials.
However, once they infest a tree they will continue to feed on it for years, causing severe damage to nutrient transport systems, which can cause massive leaf die offs, dead roots, and the death of the tree itself.
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 Emerald Ash Borer is a phloem-feeding beetle that is native to Asia and has been increasing its presence in the US. The beetle is invasive, harmful to native ash trees, and has the ability to spread (Kovacs et al., 2010). The invasive beetles cause destruction to ash trees in a gradual process, that usually lasts three years. The beetles initiate the attack along the upper trunk and bases of main branches and then work their way down (Winners, 2002). The adult beetles lay eggs on the ash tree’s bark and when they hatch, the larvae bore into the bark and feed on the transportation tissues of the tree (NCFS, 2016). This causes disruption of the movement of nutrients and water within the tree. Since the bug resides and lays eggs within the tree’s bark, they are hard to recognize until the
The emerald ash borer, Agrilus planipennis, is a beetle that was first discovered in 2002 in the US near the Detroit area and southeastern portions of Michigan. This beetle is believed to have originated in Asia. The theory is that they arrived in the states in packing material made of wood on cargo ships traveling on the St. Lawrence River, which then leads into the Great Lakes. Since 2002, this beetle has made its way into parts of Canada and now in at least eighteen states in the US (Emerald, n.d.). They are causing major destruction of Ash trees in all of these areas, and Vermont is starting to take precautions to be prepared if and when these beetles show up in The Green Mountain
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
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
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
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
The Hercules Beetle, which is native to South America, is one of the largest species of beetle in the world. The Hercules Beetle spends most of its life on the ground of the leaf covered rainforests and tropical jungles searching for food. The leafs covering the ground also help hide the beetle from predators. The Hercules Beetle is an omnivore, which means it eats both plants and animals. One of the most distinctive things about the Hercules Beetle are its pincers that look like horns, which are mainly used against other male Hercules Beetles during disputes. The Hercules Beetle has a conservation status of “threatened” and its skin type is shell.
Jane Goodall innovatively talks about the American Burrying Beetle in her story, “Hope for Animals and Their World”. She declines to loose hope that beetles are “creepy-crawlies” or “bugs.” Her way of illustrating the story is marvelous, as her text has remarkable density. She uses engaging words which captures the reader’s attention.
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
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.
Termites, carpenter ants. and other wood-boring insects quickly move into the rotting stumps. Insects play a major role in decomposing and are vital to a health ecosystem; however, insects can spread into surrounding trees, and buildings, causing thousands of dollars worth of property damage. Removing the stump reduces these pests and the risk to the home.
