Émile Roubaud
Émile Roubaud (2 March 1882 in Paris – 30 September 1962 in Paris) was a French biologist and entomologist known for his work on paludism, yellow fever and sleeping sickness. Biography In 1906-08 he worked in the French Congo, where he studied the transmission of trypanosomiasis and the role of tsetse flies. In 1909-12 he took part in a mission in Senegal, Casamance and Dahomey, where he performed research of animal trypanosomiasis. On this mission he conducted geographical distribution studies of nine tsetse fly species.Emile Roubaud (1882-1962) Service des Archives de l'Institut Pasteur In 1920, he and Félix Mesnil achieved the first experimental infection of |
Simulium
''Simulium'' is a genus of Black_fly, black flies, which may transmit diseases such as onchocerciasis (river blindness). It is a large genus with almost 2,000 species and 38 subgenus, subgenera. The flies are pool feeders. Their saliva, which contains anticoagulants, a number of enzymes and histamine, is mixed with the blood, preventing clotting until it is ingested by the fly. These bites cause localized tissue damage, and if the number of feeding flies is sufficient, their feeding may produce a blood-loss anaemia. The host's reaction to fly attacks may include systemic illness, allergic reactions or even death, presumably mediated by histamine. In humans, this systemic reaction is known as "black fly fever" and is characterized by headaches, fever, nausea, adenitis, generalized dermatitis, and allergic asthma.

Nuku Hiva
Nuku Hiva (sometimes spelled Nukahiva or Nukuhiva) is the largest of the Marquesas Islands in French Polynesia, an overseas country of France in the Pacific Ocean. It was formerly also known as ''Île Marchand'' and ''Madison Island''. Herman Melville wrote his book '' Typee'' based on his experiences in the Taipivai valley in the eastern part of Nuku Hiva. Robert Louis Stevenson's first landfall on his voyage on the ''Casco'' was at Hatihe'u, on the north side of the island, in 1888. Geography Coast Western Nuku Hiva is characterized by a steep but fairly regular coastline, indented occasionally by small bays, leading to deep valleys, which in turn lead into the interior. There are no villages on the western side. The coastline of the eastern part of the island has few places to land by sea and takes the brunt of the ocean swells. The northern side, in contrast, is indented by deep bays, the largest of which are Anahō and Hatihe'u. A third bay, 'A'akapa, is smaller and ...

Eiao
Eiao is the largest of the extreme northwestern Marquesas Islands. The island is uninhabited, but is administratively part of the commune (municipality) of Nuku-Hiva, itself in the administrative subdivision of the Marquesas Islands. As of 2022, the only settlement on the Island is a small shelter on the north coast of Vaithua bay with a water tap. There is some small manmade structures in the north of the island, most likely for archeological purposes. There is a small shrine of Mother Mary somewhere along a trail to the plateau at the top of the island. Geography Eiao is a remnant of a caldera wall in a 5 million year old volcano which measured 25 km across. The island is a 12km long and 4 km wide crescent shape measuring 50 km squared. It is often considered one of the biggest desert islands on earth. The center of this island is the high Tohuanui plateau, rising on the east side to 576 meters above sea level (1,890 feet), much of which has been devastated by herds of f ...
