Bionomics
The larvae of Mansonia occur in permanent
waters in association with aquatic plants which have roots used for attachment
by the siphon to obtain oxygen from air cells for respiration. Larvae of
some species burrow into debris on the bottom while others cling to the
roots of plants in floating masses. Water lettuce (Pistia)
is commonly used as a host plant, particularly by species of the subgenus
Mansonioides. Larvae detach and re-attach
to host plants quite readily. The females of several species are vicious
nocturnal biters. Important

Mansonia titillans of the subgenus
Mansonia is an important pest in South and Central America and in
the southern USA. It is known to transmit various arboviruses, including
Venezuelan equine encephalitis. Some species of the subgenus
Mansonioides transmit several arboviruses, but they are mainly important
as vectors of the helminths which cause Brugian filariasis in India and
Southeast Asia. Mansonia
uniformis, which is widely distributed from western Africa through
southern Asia to Japan and the Australasian Region, is a vector of
Wuchereria bancrofti in Irian Jaya. |
