Culex tritaeniorhynchus is the vector that is responsible for the spreading of Japanese encephalitis. This is a native mosquito of Northern Asia and other parts of Africa. The females of this breed mosquitoes are engaged in collecting or sucking blood from the body of large animals such as cattle, swine, etc. They are strongly anthropophilic.
The Culex tritaeniorhynchus mostly live in grasses and rice farms as they breed in still water. The species of Culex tritaeniorhynchus is part of the Culex vishnui subgroup, It is a very small mosquito species and is reddish-brown in color.
This species of mosquitoes are very harmful because they spread pathogen from one person to another. One of the most popular diseases in Japan ‘Japanese encephalitis‘ is caused due to Culex tritaeniorhynchus. If you do not know about Japanese encephalitis. So, here is a short note about Japanese encephalitis.
Japanese encephalitis which is also known as JEV was initially isolated in Japan in the year 1935. Japanese encephalitis causes infections all over the Asian continent, the western Pacific region, and some other parts of Australia. Japanese encephalitis is the most important cause of viral encephalitis all over the world.
The virus of Japanese encephalitis is transmitted naturally in an enzootic cycle among birds, pigs, and other vertebrate hosts by the Culex tritaeniorhynchus mosquito. Culex tritaeniorhynchus is not only the factor behind the spreading of Japanese encephalitis but also because of some other culex spp.
Female Anopheles is the vector that is responsible for the spreading of malaria disease from one person to another. Female Anopheles mosquito belongs to genus anopheles which was first time discovered by J.W Meigen in the year 1818.
Among the whole species of the Anopheles genus, the Anopheles gambiae is the one who can spread the most harmful parasite of malaria that is plasmodium falciparum. Anopheles is the only known carrier of malaria which helps in the transmission of encephalitis and filariasis.
Anopheles mosquitoes are easily identified because of their resting position, in which the proboscis, head, and body are held on a line to each other but at an angle to the surface. The spotted coloring on the wings of the Anopheles mosquito is due to colored scales.
Generally, mosquitoes lay eggs in water bodies so, in the same way, the Female Anopheles mosquitoes lay eggs in water containing heavy vegetation. This female mosquito deposits her eggs singly on the surface of the water.
The larvae of the Female Anopheles mosquito lies parallel to the surface of the water and breathe through posterior spiracular plates which are present on the abdomen. Usually, the life cycle of larvae of Female Anopheles is from 18 days to some weeks.
As in the above question, we talk about name the vector of Japanese encephalitis and malaria so you can easily relate the Female Anopheles to it.
