Comprehensive Description

provided by Smithsonian Contributions to Zoology
Culex (Culex) nigripalpus Theobald

This is a widely distributed species, occurring from Texas, Tennessee, North Carolina, and the Bahamas south to Ecuador and Brazil as far south as São Paulo. It probably occurs throughout the Antilles, although this survey provided the first known records from Dominica. The larvae are found in a wide variety of freshwater habitats, either permanent or semipermanent, and they may be found in leaf axils, artificial containers and temporary ground pools. It is primarily a zoophilic, outdoor species, although it will bite man and occasionally has been taken in houses. Eastern Equine Encephalitis has been isolated from C. nigripalpus in Trinidad and St. Louis Encephalitis virus from it in Jamaica.

Culex nigripalpus

provided by wikipedia EN

Culex nigripalpus (Florida SLE mosquito) is a species of medium-sized, dark, blood-feeding mosquito of the family Culicidae.[1]

Distribution

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]

Ecology

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]

Medical significance

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]
