2020年10月13日 · Common names: Karoo brown locust or brown locust (English); tsie e sootho (Sesotho), xibudzunga (Xitsonga) Locusts are grasshoppers that are able to exist in either a solitary or gregarious phase. The gregarious phase lives in swarms, are able to migrate over large areas and may even darken the sky in this stage.

2024年5月27日 · Tsetse flies are a type of blood-sucking insect that lives in diverse locations in Sub-Sahara Africa. There are about 27 different species of tsetse flies, which have been given the scientific name of Glossina. The pronunciation of tsetse is tse-see, according to Merriam Webster.

2016年9月19日 · Tsetse flies are the scourge of Central Africa. The flies are vectors for the disease nagana, also known as African animal trypanosomiasis (AAT), in wild and domestic animals, and a similar disease among humans that is known as sleeping sickness, or human African trypanosomiasis (HAT).

2020年6月16日 · The tsetse fly (Genus Glossina) is notable for two things: it carries parasites called trypanosomes, which cause sleeping sickness in humans and nagana in cattle in sub-Saharan Africa; and it gives birth to live young.

2014年4月24日 · The genome of the tsetse fly—a disease-ridden insect with surprisingly mammalian biology that stalks the people and livestock of sub-Saharan Africa—has been decoded, a team of 146 scientists...

2020年11月2日 · Tsetse flies, which miraculously birth young bigger than the mother, show us what science is about. Across most of the animal kingdom, offspring are born smaller than their parents. Astonishingly, several families of insects, including tsetse flies, break this simple rule, and mothers produce offspring their own size or even larger.

Caused by two subspecies of Trypanosoma brucei, human African trypanosomiasis (HAT) or sleeping sickness is present in Central, West, and East Africa. HAT is transmitted by the bite of an infected glossina, or tsetse fly. The reservoir is mainly human in the gambiense form and animal in the rhodesiense form. In 2006, 11 868 new cases were reported.

2019年3月5日 · Tsetse flies transmit African trypanosomiasis (commonly known as sleeping sickness) to animals and humans in 36 sub-Saharan countries. Infection is usually confined to rural areas and is therefore most likely to affect those planning on visiting farms or game reserves .

Tsetse flies (Glossina spp.), are a scourge of Africa. There are close to ten economically important species, all of which feed on blood and transmit the Trypanosoma parasites, which are responsible for sleeping sickness in humans and animal trypanosomosis or "Nagana" in cattle.
