The tsetse fly is predominant found in large areas of sub-Saharan Africa where there is human settlement and agriculture. The tsetse flies are cousins of the house fly, however they are larger than a common house fly. Approximate length of a house fly is 6 to 7 mm while a tsetse fly ranges anywhere from 6 to 16 mm in length. There are approximately 22 different kinds or species of tsetse fly living on the continent of Africa presently. The scientific name for the tsetse fly is Glossina. Each of the
Since Trypanosoma brucei are parasitic, their environment is their host. The most common carrier is the African native tsetse fly, which is abundant in western and central regions of the continent (Kagbadouno et al. 2012). Cases of sleeping sickness have also been found scattered throughout the eastern and southern portions of Africa, but it is less common in these areas. Tsetse flies typically reside in African forests and woodlands. They make up about a quarter of the continent’s landscape, have
This paper tells about different methods as to which parasites enter the body. Each parasite is unique as to what problems they cause or diseases they carry. Some of these parasites can prove fatal unless treated, and if they are not treated carefully, they could still complicate an individual’s health. This paper also includes the places these parasites thrive and as to how to treat these parasites. Although most of these parasites are treatable, the treatment required is completely dependent upon
I. A coma’s technical name is “Trypanosomiasis.” Many people think the person is asleep, but the person is actually in a deep state of unconsciousness. It happens worldwide, but mostly in Africa. There are about 50,000-70,000 cases a year. When a person is in a coma, they are unresponsive since they are unconscious. They also do not respond to their environment. First recognized two centuries ago, comas can be deadly because of damage to the brainstem. II. Comas are caused by various reasons, like
1986 but the disease has been greatly reduced over time and only 22 cases were reported in 2015. This disease will probably be the first parasitic disease to be completely eradicated in humans. Filariasis This disgusting worm parasite is spread by flies and mosquitoes. The adult worm spreads its larvae throughout the host’s lymphatic system and causes the lymph nodes to become clogged up. This also makes the tissue in the host’s body to swell up and create massive muscle deformations, otherwise known
The fruit fly experiment is used as a way to introduce the study of genetics to students. It was first used by Thomas Morgan Hunt in 1910. The significance for using fruit flies, also known as Drosophila Melanogaster is because they’re great to work with in research scenery. They’re relatively easy to care for, especially when comparing to larger organisms like rats, or rabbits. They mate readily, take approximately two weeks to develop, and only carry four pair of chromosomes (Shanholtzer, 2012)
hotel; and Lord of the Flies, where a group of kids trapped on an island start to fight among themselves while waiting for rescue. These are just some examples of stories that show this question, and Franz Kafka’s “Metamorphosis” and David Cronenberg’s The Fly illustrate this point further. The main similarity between the two stories is that the main character in each character in each story is transformed into a giant insect. Seth Brundle in The Fly becomes a giant fly/human hybrid, and in Kafka’s
Just Like Mosquitoes Mosquitoes have three purposes in the world. The first is to suck blood from multiple diseased animals and spread various infections to humans. The second is to bug, annoy, and make as many people mad as possible. The third is to reproduce and make as many babies as they can to carry on the family tradition. To make a parallel to this topic would like discussing telemarketers. Nearly every aspect of a mosquito has a direct connection to telemarketers such as their nearly countless
Summary House-flies are known to carry easily transmitted diseases. Home owners have many options to keep flies out of their homes but many are unsustainable such as insecticides or fly paper. Fly screens have been identified as the best solution to keep flies out of the home because they have a small local environmental footprint and are also cheap to manufacture. Researchers in 1964 at the London School of Hygiene and Tropical Medicine ran experiments to conclude that mesh of 2.17 ± 0.09 mm should
Fishing to some people may just be fishing. But fishing to the people who have read A River Runs through It some time in their life, is a gift. Whether fishermen use bait, worms, or George's flies it is that much sweeter to catch some trout with a brother under one arm and a father on the other. The river and fishing made such a big impact on the Maclean family that it is the root of this book. The Macleans compared the river to life, went fishing to answer questions, and created a river that
At a minuscule 1/16 of an inch long, you would think that a springtail is such a tiny creature that you wouldn't even notice him. Unfortunately, springtails travel in packs, creating bio-masses large enough to disturb you; especially when clumps of them are floating in your pool. These small insects huddle together in moist areas, eating decaying materials and jumping high into the air when disturbed. They are attracted to moisture, and as such often find their way into swimming pools where they
MAY-FLY FISHING Wednesday, February 10th, 2010 There are two flies to which the term May-fly is applied. The first, which is known by anglers generally as the May-fly, is the green drake, a large yellowish fly, which makes its appearance on some streams in great numbers, from the middle to the end of June. Trout are very fond of them, seizing greedily every unlucky individual that ventures on the water; and a couple of them put on a small hook, and allowed to play on the surface will be found
Analysis of Lord of the Flies by William Golding William Golding’s Lord of the Flies is a sordid tale about a group of kids who are stranded on a deserted island after their plane crashes. The story is set during the Atomic War and plenty of references are made to the fact. However, the real key to the story lies in the role of Beelzebub, Lord of the Flies. Beelzebub has a central role in the story as he represents the Beast, or evil, that dwells within all humans. The Beast cannot be hunted and
Jack as Symbol of Anarchy and Savagery in Lord of the Flies Golding's motives for choosing the island setting for the novel, Lord of the Flies was to have the characters isolated, where the laws of their governments could not reach them. The boys on the island represented a microcosm of world society. Golding chose children because they have not yet been fully conditioned by society to understand right from wrong, and thus are guided by their instinct and what is inherent within them. Golding
Lord of the Flies, which was written by William Golding, and The Coral Islands, which is written by R.M. Ballantyne were two books about British boys who were stuck on an island. Lord of the Flies is an imitation of The Coral Island. In Lord of the Flies the scene is set up with two boys stranded on an island from a plane crash, in which all the adults died. These boys were schoolboys that later found more boys that were stranded on the island by blowing on a conch shell. They all get together and
instinctual hunger for power. Both of these traits together make us human, but imbalance of these traits in some people can alter our being. These traits are necessary for our survival, but too much can create toxic environments. In the novel Lord of the Flies, William Golding uses symbols to tell the reader more about human traits and provides a platform that shows the interactions between people with different balances of traits; Golding then shows the possible outcome of the conflict these traits create
the Flies had endured many occupations throughout his lifetime which include being a sailor, lecturer, schoolmaster, and actor. William Golding joined the Royal Navy in 1940, and was able to fight against battleships, submarines and aircraft. He had gone through the war as a Lieutenant, and was present at the sinking of the Bismarck. After the war, William Golding returned back to a school by the name of Bishop Wordsworth’s School in Salisbury, where he wrote his first novel Lord of the Flies, which
the best of people can be bitter by their own nature. In the novel, Lord of the Flies, William Golding removes the restraints of society to prove that it is human nature to live primitively and that evil lies within all of us. The sanctions of society begin to deteriorate due to the loss of communication, Jack’s obsession with hunting, and the inhumane nature of Jack and his “tribe”. In the novel, Lord of the Flies, the civilization weakens due to a meeting breaking down to complete chaos. In chapter
said that, “the only thing we have to fear is fear itself”. Fear is a product of the absence of knowledge and thoughts that are blown out of proportion. As humans we are scared of the unknown and what it conceals from us. In the novel Lord of the Flies by William Golding, a group of children crash land on an unknown island without adults. As time passes, the kids become uneasy and try to seek comfort in their leaders. When their imagination takes over, the unknown soon ignites their fear and apprehension
Evil exists in all human beings, even children. This is proven in William Golding's novel Lord of the Flies in which a group of youthful, inncocent boys are stranded without any contact with the outside world. The boys are not in the civil surrondings that they are used to, but their instincts kick in and their ultimate goal is to survive, together. The first sense of security is when all of the boys find eachother. They are given hope. Hope that is immediately lost when the division between the
