Anopheles nili Theobald, 1904 | |
Anopheles nili is a species of mosquito [1] in the Culicidae family. [2] It comprises the following elements: An. carnevalei, An. nili, An. ovengensis and An. somalicus. [3] The scientific name of this species was first published in 1904 by Theobald. [4] It is the main mosquito species found in the south Cameroon forest zone which bites humans. [5] It is known as a problematic carrier of malaria, [6] although newly discovered, closely related species in the same genus have also been found to interact with A. nili as a disease vector. [7] In that, they both have similar feeding habits on local targets in the Cameroon region. [8]
For more information, see mosquito life cycle.
Similar to all mosquitoes, Anopheles nili go through a life stages of egg, larva, pupa, then emerge as adults. [9]
Anopheles nili is a generalist species, meaning that they may adapt to different environments to survive. [10] This has worked to the detriment of human health, as the mosquito species has become very well adapted to spawning in dam reservoirs. [11] As A. nili shifts its habitats to areas of high human concentration, they also begin to mate and spawn their young in nearby reservoirs, such as dams. This of course allows spread of malaria to the nearby populace. [9]
Mosquitoes are well known carriers of malaria, A. nili being without exception. As a native species that has adapted to live with the environmental changes of Cameroon it marks itself as a common species found to be carrying malarial parasites in the newly built dams of Cameroon. [12]
Dam development in Cameroon marks itself as a grave detriment to native populations health, through the spread of malaria. Dam developments in particular, because mass environmental changes alter the balance of disease hosts, vectors, and parasite development. [9] Studies have been made in recent history before and after dams are built in Cameroon to better understand the method in how malaria is transmitted. It was found in studies dating back as long as1979, where native mosquitoes, like A. nili, favoured dams as breeding grounds; and thus ripe for malaria breakouts. [13] It was also found in those researches that the malarial parasites are found in the midgut of mosquitoes, that being an example of the parasites persistence. [14]
Anopheles is a genus of mosquito first described by J. W. Meigen in 1818, and are known as nail mosquitoes and marsh mosquitoes. Many such mosquitoes are vectors of the parasite Plasmodium, a genus of protozoans that cause malaria in birds, reptiles, and mammals, including humans. The Anopheles gambiae mosquito is the best-known species of marsh mosquito that transmits the Plasmodium falciparum, which is a malarial parasite deadly to human beings; no other mosquito genus is a vector of human malaria.
Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria. It is responsible for around 50% of all malaria cases. P. falciparum is therefore regarded as the deadliest parasite in humans. It is also associated with the development of blood cancer and is classified as a Group 2A (probable) carcinogen.
Plasmodium ovale is a species of parasitic protozoon that causes tertian malaria in humans. It is one of several species of Plasmodium parasites that infect humans, including Plasmodium falciparum and Plasmodium vivax which are responsible for most cases of malaria in the world. P. ovale is rare compared to these two parasites, and substantially less dangerous than P. falciparum.
A mosquito net is a type of meshed curtain that is circumferentially draped over a bed or a sleeping area, to offer the sleeper barrier protection against bites and stings from mosquitos, flies, and other pest insects, and thus against the diseases they may carry. Examples of such preventable insect-borne diseases include malaria, dengue fever, yellow fever, zika virus, Chagas disease and various forms of encephalitis, including the West Nile virus.
The Anopheles gambiae complex consists of at least seven morphologically indistinguishable species of mosquitoes in the genus Anopheles. The complex was recognised in the 1960s and includes the most important vectors of malaria in sub-Saharan Africa, particularly of the most dangerous malaria parasite, Plasmodium falciparum. It is one of the most efficient malaria vectors known. The An. gambiae mosquito additionally transmits Wuchereria bancrofti which causes lymphatic filariasis, a symptom of which is elephantiasis.
Avian malaria is a parasitic disease of birds, caused by parasite species belonging to the genera Plasmodium and Hemoproteus. The disease is transmitted by a dipteran vector including mosquitoes in the case of Plasmodium parasites and biting midges for Hemoproteus. The range of symptoms and effects of the parasite on its bird hosts is very wide, from asymptomatic cases to drastic population declines due to the disease, as is the case of the Hawaiian honeycreepers. The diversity of parasites is large, as it is estimated that there are approximately as many parasites as there are species of hosts. As research on human malaria parasites became difficult, Dr. Ross studied avian malaria parasites. Co-speciation and host switching events have contributed to the broad range of hosts that these parasites can infect, causing avian malaria to be a widespread global disease, found everywhere except Antarctica.
Anopheles dirus is a vector of malaria in Asian forested zones.
Anopheles (Cellia) subpictus is a species complex of four species of mosquito belonging to the genus Anopheles.
Anopheles albimanus is a species of mosquito in the order Diptera. It is found in coastal Central and South America, the Caribbean, and Mexico. It is a generalist species and capable of wide dispersion. A. albimanus is a common malaria vector.
Anopheles stephensi is a primary mosquito vector of malaria in urban India and is included in the same subgenus as Anopheles gambiae, the primary malaria vector in Africa. A. gambiae consists of a complex of morphologically identical species of mosquitoes, along with all other major malaria vectors; however, A. stephensi has not yet been included in any of these complexes. Nevertheless, two races of A. stephensi exist based on differences in egg dimensions and the number of ridges on the eggs; A. s. stephensisensu stricto, the type form, is a competent malaria vector that takes place in urban areas, and A. s. mysorensis, the variety form, exists in rural areas and exhibits considerable zoophilic behaviour, making it a poor malaria vector. However, A. s. mysorensis is a detrimental vector in Iran. An intermediate form also exists in rural communities and peri-urban areas, though its vector status is unknown. About 12% of malaria cases in India are due to A. stephensi.
Anopheles darlingi, the American malaria mosquito, is a species of mosquito in the family Culicidae. A. darlingi is one of the major species of mosquito known to be responsible for malaria in the Amazonian regions. It has a wide range of geographic distribution that stretches from Mexico and Argentina but it has also been found to populate in areas affected by deforestation and environment changes due to humans.
Attractive toxic sugar baits (ATSBs) are oral insecticides designed to reduce malaria infections by killing the host vector – the mosquito – rather than the parasite itself.
Plasmodium cynomolgi is an apicomplexan parasite that infects mosquitoes and Asian Old World monkeys. In recent years, a number of natural infections of humans have also been documented. This species has been used as a model for human Plasmodium vivax because Plasmodium cynomolgi shares the same life cycle and some important biological features with P. vivax.
Anopheles (Cellia) karwari is a species complex of zoophilic mosquito belonging to the genus Anopheles. It is found in India, and Sri Lanka, Bangladesh, Sumatra, and Java. A. karwari is a member of the Maculatus Group and the second scarcest species reported from Indonesia. Female is blood sucking and involved in transmitting Plasmodium falciparum, thus an important malarial vector. It is considered a secondary vector in the Australian region, but its vectorial status in South-East Asia was unknown.
Anopheles freeborni, commonly known as the western malaria mosquito, is a species of mosquito in the family Culicidae. It is typically found in the western United States and Canada. Adults are brown to black, with yellow-brown hairs and gray-brown stripes on the thorax. Their scaly wings have four dark spots, which are less distinct in the male.
Quartan fever is one of the four types of malaria which can be contracted by humans.
Anopheles funestus is a species of mosquito in the Culicidae family. This species was first described in 1900 by Giles. The female is attracted to houses where it seeks out humans in order to feed on their blood, mostly during the night. This mosquito is a major vector of malaria in sub-Saharan Africa.
Anopheles arabiensis is a zoophilic species of mosquito and a vector of disease endemic to Africa.
Anopheles moucheti is a species of mosquito. It is an anthropophile. It can be mainly located in Congo Basin forest, Central Africa. It was the main vector of malaria.
