Culex quinquefasciatus (earlier known as Culex fatigans) is the vector of
lymphatic filariasis caused by the nematode

Nematode

The nematodes or roundworms are the most diverse phylum of pseudocoelomates, and one of the most diverse of all animals. Nematode species are very difficult to distinguish; over 28,000 have been described, of which over 16,000 are parasitic. It has been estimated that the total number of nematode...

Primary vector of Lymphatic Filariasis in India

This is the primary vector of fiariasis in India. It is a strong winged domestic species
seen all over India in and around human dwellings. Rapid urbanization and industrialization
without adequate drainage facilities are responsible for its increased dispersal.
The species is highly anthropophlic (they prefer human blood). They enter the houses at
dusk and reach maximum density by midnight. The peak biting time is at midnight.
Legs, particularly below the knee are the preferred biting sites. During day, it may be
seen resting indoorson walls, underneath furniture, hanging cloths and in dark corners.

The Bionomics

It breeds profusely in dirty water collections, viz. stagnant drains, cesspools, septic
tanks with leak, burrow pits, and in fact all organic polluted water collection.
In optimum temperature and humidity, the life cycle will be completed in 7 days,
passing through the 4 stages: egg, larva, pupa and adult.
