Abstract
Mosquitoes exploit almost all types of aquatic habitats for breeding. Prevailing physicochemical parameters in these habitats are important factors for survival and development of mosquito. Here, six water samples from Atlantic Ocean, River, well, distilled (control), rain and borehole water were used to culture Anopheline eggs collected from pure bred of Kisimu species. The development of eggs to 1st, 2nd, 3rd and 4th instars larval, pupal and adult stages were observed from day 1 to 6 using six replicates of each water sample. The number of eggs laid (fecundity) by the emerged adults were estimated using counting microscope. Level of development in emerged adults was determined using the wing size. The analysis of the physicochemical parameters of the water samples was carried out in the Nigerian Institute of Marine and Oceanography. The physicochemical characteristics were compared with the
