Culex nigripalpus (Florida SLE mosquito) is a species of medium-sized, dark, blood-feeding mosquito of the family Culicidae. [1]
Culex nigripalpus has been found to occur in the following countries: Anguilla, Bahamas, Barbados, Belize, Brazil, Colombia, Costa Rica, Cuba, Dominica, Dominican Republic, Ecuador, El Salvador, French Guiana, Grenada, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Jamaica, Martinique, Mexico, Montserrat, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Saint Lucia, Saint Vincent and the Grenadines, Suriname, Trinidad and Tobago, United States, Venezuela, Virgin Islands. [2] In the United States, it is found from Texas to North Carolina in warm, humid coastal habitats and in the Mississippi River basin as far north as Kentucky. [1]
Culex nigripalpus larvae live in fresh water in semi-permanent or permanent marshes, ditches, retention ponds, and grassy pools, and females prefer to lay eggs in freshly flooded ditches. [3] [2]
Culex nigripalpus is a principle disease vector in Florida – the primary enzootic vector to wild birds and the primary epidemic vector to humans of the Saint Louis encephalitis (SLE) virus. [1] [4] It has been experimentally demonstrated to be capable of transmitting West Nile virus (WNV). [5] Its habit of feeding on both birds and humans gives it significant potential for transmission of zoonotic infections from birds to humans. It is also a vector of transmission of Eastern equine encephalitis (EEE), dog heartworm, and Avian malaria. [1] [2] [6]
Mosquitoes are members of a group of almost 3,600 species of small flies within the family Culicidae. The word "mosquito" is Spanish and Portuguese for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts.
West Nile fever is an infection by the West Nile virus, which is typically spread by mosquitoes. In about 80% of infections people have few or no symptoms. About 20% of people develop a fever, headache, vomiting, or a rash. In less than 1% of people, encephalitis or meningitis occurs, with associated neck stiffness, confusion, or seizures. Recovery may take weeks to months. The risk of death among those in whom the nervous system is affected is about 10 percent.
Arbovirus is an informal name for any virus that is transmitted by arthropod vectors. The term arbovirus is a portmanteau word. Tibovirus is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals and plants. In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and viral hemorrhagic fever may also occur.
Saint Louis encephalitis is a disease caused by the mosquito-borne Saint Louis encephalitis virus. Saint Louis encephalitis virus is related to Japanese encephalitis virus and is a member of the family Flaviviridae. This disease mainly affects the United States, including Hawaii. Occasional cases have been reported from Canada, Mexico and the Caribbean, including the Greater Antilles, Trinidad and Tobago, and Jamaica.
Culex is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles.
Culex (Culex) tritaeniorhynchus is a species of mosquito and is the main vector of the disease Japanese encephalitis. This mosquito is a native of northern Asia, and parts of Africa. Females target large animals for blood extraction, including cattle and swine, and are strongly anthropophilic.
Culex pipiens, commonly referred to as the common house mosquito, is a species of mosquito. House mosquitoes are some of the most common mosquitoes in the United States. More specifically, Culex pipiens is considered as the northern house mosquito, as it is the most common mosquito to the northern regions of the US. North of the 39th parallel north in the US, only C. pipiens are present, whereas south of the 36th parallel north, only C. quinquefasciatus are present. Additionally, they can be found in both urban and suburban temperate and tropical regions across the world.
Culex restuans is a species of mosquito known to occur in Canada, the United States, Mexico, Guatemala, and Honduras. It is a disease vector for St. Louis encephalitis and West Nile virus. In 2013 West Nile Virus positive specimens were collected in Southern California.
Rocio viral encephalitis is an epidemic flaviviral disease of humans first observed in São Paulo State, Brazil, in 1975. Low-level enzootic transmission is likely continuing in the epidemic zone, and with increased deforestation and population expansion, additional epidemics caused by Rocio virus are highly probable. If migratory species of birds are, or become involved in, the virus transmission cycle, the competency of a wide variety of mosquito species for transmitting Rocio virus experimentally suggest that the virus may become more widely distributed. The encephalitis outbreak in the western hemisphere caused by West Nile virus, a related flavivirus, highlights the potential for arboviruses to cause severe problems far from their source enzootic foci.
Culex quinquefasciatus, commonly known as the southern house mosquito, is a medium-sized mosquito found in tropical and subtropical regions of the world. It is a vector of Wuchereria bancrofti, avian malaria, and arboviruses including St. Louis encephalitis virus, Western equine encephalitis virus, Zika virus and West Nile virus. It is taxonomically regarded as a member of the Culex pipiens species complex. Its genome was sequenced in 2010, and was shown to have 18,883 protein-coding genes.
Culex modestus is a species of blood-feeding mosquito of the family Culicidae. It has been experimentally demonstrated to be capable of transmitting West Nile virus (WNV), and its habit of feeding aggressively on both birds and humans gives it significant potential for transmission of zoonotic infections from birds to humans. It is believed to be the principle bridge vector of WNV between birds and humans in southern France and is thought to have played a role in WNV transmission in the Danube delta, Caspian and Azov sea deltas, and the Volga region in Russia. It has also been implicated in Tahyna virus and Lednice virus transmission in France and Slovakia, respectively.
Aedes canadensis, the woodland pool mosquito, is an aggressive, day biting mosquito that can be a vector of a number of diseases which is found mainly in eastern North America.
Hart Park virus, or HP virus, is a single-stranded RNA arbovirus that is primarily transmitted through mosquitoes. The HP virus is classified in the Rhabdoviridae family and is related to the viral agents that cause rabies and vesicular stomatitis. The exact date of discovery of this virus is uncertain, but its presence in the entomological community dates back as far as 1964. Because of its relatively recent discovery, its exact effect on hosts is uncertain. Currently, there is no known disease affiliated with the Hart Park virus.
Aedes japonicus, commonly known as the Asian bush mosquito or the Asian rock pool mosquito, was first described by Theobald in 1901 from Tokyo, Japan and has four known subspecies Ae. j. japonicus, Ae. j. shintienensis, Ae. j. yaeyamensis, and Ae. j. amamiensus. They are competent arbovirus vectors known to transmit the West Nile virus as well as Japanese and St. Louis encephalitis. They are listed as an invasive species by the Global Invasive Species Database.
West Nile virus (WNV) is a single-stranded RNA virus that causes West Nile fever. It is a member of the family Flaviviridae, from the genus Flavivirus, which also contains the Zika virus, dengue virus, and yellow fever virus. The virus is primarily transmitted by mosquitoes, mostly species of Culex. The primary hosts of WNV are birds, so that the virus remains within a "bird–mosquito–bird" transmission cycle. The virus is genetically related to the Japanese encephalitis family of viruses.
Mansonia (Mansonioides) annulifera is a species of zoophilic mosquito belonging to the genus Mansonia.
Culex (Culex) fuscocephala is a species of mosquito belonging to the genus Culex. It is found in Indonesia, and Sri Lanka, Bangladesh, Cambodia, China, Guam, Hong Kong, Indonesia, Japan, Laos, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Singapore, Thailand, Timor, and Vietnam. It is a vector of Japanese encephalitis virus.

It is found in India, Sri Lanka, Bangladesh, Cambodia, China, Hong Kong, India, Indonesia, Japan, Laos, Malaysia, Myanmar, Nepal, New Guinea (Island); Papua New Guinea, Pakistan, Philippines, Taiwan, Thailand, Vietnam. In 1976, it was identified as a major vector of Japanese encephalitis virus, in India. From an experiment, it was evident that aqueous solution of Calotropis gigantea leaves possess larvicidal activity, mosquito repellent activity and ovicidal activity against Culex gelidus.
Culex (Oculeomyia) infula is a species of mosquito belonging to the genus Culex. It is found in Bangladesh, India, Indonesia, Malaysia, Myanmar, Nepal, Philippines, Singapore, Sri Lanka, Thailand, and Vietnam.
