An entomological surveillance was carried out to study the mosquito species composition and larval habitats characterization
in Dhaka, Bangladesh. A total of 6,088 mosquito larvae belonging to 12 species (
Ae. aegypti, Ae. albopictus, An. barbirostris,
An. peditaeniatus, An. vagus, Cx. gelidus, Cx. hutchinsoni, Cx. quinquefasciatus, Cx. tritaeniorhynchus, Mn. annulifera, Mn.
uniformisand Tx. splendens
) were collected from 14 types of habitats during the study period.
found as dominant (21.7/500ml) species followed by
(10.53/500ml). Dissolve oxygen and chlorophyll
awere the preeminent predictor for the abundance of all collected mosquito larvae except Ae. aegypti. Water temperature was
positively associated with An. vagus (r = 0.421, p = <0.001), An. barbirostris (r = 0.489, p = <0.001) and An. peditaeniatus (r
= 0.375,p = <0.001) breeding. Water depth, distance from nearest house, emergent plant coverage and alkalinity were found
as the basis of larval abundance.Every
(r = 0.359, p = 0.001) were found positively associated
with chemical oxygen demand while
showed negative association (r = -0.115, p = 0.0297). Culex larvae were
found to share their habitats with
(8.86%) andAnopheles (32.81%) but Anopheles was not found to coexist with Aedes.
Marked differences between the physicochemical characteristics of different types of larval habitats were observed. This study
highlighted that various physicochemical factors affect the presence and abundance of mosquito larvae
