Culex (Culex) tritaeniorhynchus is a species of mosquito and is the main vector of the disease Japanese encephalitis. [1] This mosquito is a native of northern Asia, and parts of Africa (northeast and sub-Saharan). [2] Females target large animals for blood extraction, including cattle and swine, and are strongly anthropophilic. [3]
Culex or typical mosquitoes are 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 .
The most important vector is Culex tritaeniorhynchus, which feeds on cattle in preference to humans. The natural hosts of the Japanese encephalitis virus are birds, not humans, and many believe the virus will never be eliminated. [35] In November 2011, the Japanese encephalitis virus was reported in Culex bitaeniorhynchus in South Korea. [36]
The vast majority have been Culex mosquitoes, a primary vector for West Nile virus. But another mosquito species that does not carry the virus, Aedes aegypti, has also become more common in Las Vegas.
Japanese encephalitis – Several mosquito vectors, the most important being Culex tritaeniorhynchus. West Nile virus – Vectors: vary according to geographical area; in the United States Culex pipiens (Eastern US), Culex tarsalis (Midwest and West), and Culex quinquefasciatus (Southeast) are the main vectors.
The virus is transmitted through mosquito vectors, as well as through contact with the tissue of infected animals. Two species— Culex tritaeniorhynchus and Aedes vexans —are known to transmit the virus. [ 7 ]
