Vectors of Bancroftian Filariasis

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.

Revalence and distribution of bancroftian filariasis vectors:
    Culex 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 vectors:
    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
M.annulifera , M.uniformis and M. indiana, are the 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.
