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
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
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
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
Lord of the Flies The classic novel Lord of the Flies by William Golding is an exciting adventure deep into the nether regions of the mind.

Throughout his story, Golding demonstrates the true nature of people coming out into the open - manifesting itself more openly after being restrained by society for so long. At the start of Lord Of The Flies, there is chaos amidst horrendous storms, with panicky schoolboys unregulated and vulnerable. Together though, they set about their predicament in a very well meaning, sophisticated way - everything is orderly and civilised in true boy-scout fashion
Lord of the Flies The main theme of Lord of the Flies is that moral nature is not instinctive in mankind. There is a capacity for evil in all people, and their morality is superficial. Nonetheless, it is this moral integrity that must continue in order for a person to be ethical, for society to be maintained, and to keep society from falling in on itself. Society holds everyone together. Without the rules and the structure, evil in everyone becomes more prominent, and ideals, values, and basics
disturbed mostly because the people who committed these acts are human like the rest of us, meaning basically everyone is capable of causing such a disturbance. William Golding came to the same conclusion in his book Lord of the Flies. Throughout his novel, Lord of the Flies, Golding illustrates mans inhumanity to man. Using conflict between characters, Golding shows how easy it can be for innocents to become evil. First of all, Roger throws stones at Henry. Henry plays on the beach quietly, and Roger

Lord of the Flies dealt with changes that the boys go through as they gradually got use to the stranded freedom from the outside world. Three main characters pictured different effects on the other boys. Jack Merridew began as the bossy and arrogant leader of a choir. The freedom of the island allowed him to further develop the darker side of his personality as the Chief
