Present study is based upon experimental
work to observe the effect of different physical ecological
factors on emergence of mosquito larvae belonging to
three Anopheles species (An. subpictus , An. stephensi and
An. culicifacies) ,one Culex species (Cx. quinquefasciatus)
and one Aedes species (Ae. aegypti) . Effect of different
ranges of temperature, pH value and intensities of light
was observed on emergence of larvae of selected species
of mosquitoes in presented study. Separate experimental
setups were established for estimating effect of each
physical ecological factor. Higher water temperature
range, high pH value of water and unavailability of light
proved unfavorable for emergence of mosquito larvae.
Effect of rise in temperature caused the faster
developmental rate in all species; whereas rise in pH and
darkness delayed the developmental phase.
