Identification and subsequent elimination of the most productive containers in a given area may potentially reduce mosquito density to below a level at which dengue transmission may be halted.
Brackish water habitats with Aedes larvae in Thannamunai and Jaffna. Andreadis There is no specific guidance on control of this mosquito species, although much of the guidance for other container breeding species, like A biting nuisance reported in Switzerland led to the identification of this mosquito species here in 2008 [5].
Larvae mature through four instars (stages), in the last stage developing into pupae, which subsequently change into adults that emerge at the water’s surface.
