Culex quinquefasciatus is the principal vector of bancroftian filariasis in India.
- Culex quinquefasciatus
breeds in polluted water bodies such as cesspits, drains, septic tanks, unused wells,
storm water canals etc.,
Prevalence and distribution of bancroftian filariasis vectors:
Culex quinquefasciatus is an ubiquitous species and abundant in tropical and subtropical countries.
Anopheles vectors:
The genus Anophelesis important in the transmission of periodic
W.bancrofti in Africa, Southern Asia and the island of New Guinea.
It is also a significant vector of periodic B.malayi in Southern Asia. New transmission and distribution records include A. gambiae from the island of Grande Comore, and A. flavirostris from Sabah.,
Aedes species such as A.polynesiensis, A.samoanus are mainly distributed
in Samoa and French Polynesia and A.poecilius in Phillippines
Vectors of Brugian Filariasis
The vectors of brugian Filariasis require the presence of hydrophytes (water weeds) for completing their life cycle. The larvae of these mosquitoes get attached to the roots of water plants like Pistia, Eichornia and Salvinia to draw oxygen.
Prevalence and distribution of Brugian vectors
Mansonioides includes the important vectors of lymphatic filariasis
caused by B.malayi in Southern and south-eastern Asia.
Mansonia vectors are
mainly from India, Indonesia, Malaysia and Thailand.
