The Tsetse Fly 1. The tsetse fly poses many dangers to the environment and to animals. This fly has been responsible for conveying a disease called African trypoanosomiasis (sleeping sickness). Sleeping sickness can be fatal‚ and in areas of interest it is responsible for 40‚000 deaths per year- just in humans. Considering that there are 23 different species of tsetse flies‚ this could pose a problem. 2. Traditionally‚ scientists would trap the flies using electric blue cloth (this would

a vector-borne parasitic disease. Trypanosoma which are the parasites are protozoa transmitted to humans by tsetse flies. Tsetse flies live in Africa‚ and they are found in vegetation by rivers and lakes‚ gallery-forests and vast stretches of wooded savannah. Sleeping sickness occurs only in sub-Saharan Africa‚ in regions where tsetse flies are endemic. There are many regions where tsetse flies are found‚ but sleeping sickness is not. The rural populations that live in such environments and depend

Trypanosomiasis African Trypanosomiasis‚ also known as "sleeping sickness"‚ is a parasitic disease of people and animals caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly‚ which is found only in rural Africa. Although the infection is not found in the United States‚ historically‚ it has been a serious public health problem in some regions of sub-Saharan Africa covering about 37 countries and 60 million people

Glossina swynnertoni is a tsetse species with extremely limited geographical distribution. It occupies a very small part of East Africa covering northern Tanzania (Arusha and Manyara regions and parts of Shinyanga and Mara regions) and the adjoining Maasai Mara in southwestern Kenya [1-3]. In its area of distribution it inhabits dry woodlands of savannah at an attitude range of 900 – 1800 metres above sea level [4‚ 5] and has preference for more open vegetation types provided that some small thickets

rural Africa. It is caused by a protozoan called trypanosome brucei‚ which is a sub species of the trypanosome parasite. The vector-borne parasite is transmitted through the bite of tsetse fly when animals and humans become in contact with the fly. The single celled protozoa have complex life cycle spent partly in the tsetse fly and partly in the mammalian bloodstream. Human African trypanosomiasis is responsible for infecting and attacking more than 10‚000 people each year and kills hundreds of thousands

Sickness is an infectious disease caused by the protozoan parasite Trypanosoma brucei. The parasite is a eukaryote‚ as it has a fully functioning mitochondria and other membrane-bound organelles. An infection is caused from the infected bite of the tsetse fly (also known as genus Glossina)‚ which can inject harmful parasites that once in the body‚ they gradually invade it. Over the course of history‚ African Sleeping Sickness has only been known since the late 19th century and that was only because

The evolution and primary function of zebra stripes According to ontological evidence‚ zebras’ background coloration is black. The white stripping appears at a later developmental phase. The development of zebra stripping can thus be viewed as an evolutionary response (Egri et al.‚ 2011). Any discussion regarding the evolutionary purpose of zebra stripes is inevitably traced back to Darwin and Wallace. While Wallace suggested that zebra stripes developed as a camouflaging mechanism against attacks
