Physicochemical as Well Biological Parameters of Waste Water of the Last Chamber of the Septic Tank is Advocacy to the Hypothesis - ‘A New Ecosystem of Aedes SP. Mosquito’: A Survey and Observations

Abstract

Aedes sp. Mosquito a global life threatening insect,“it bred and develop in the clean and clear water”, is an widely accepted theory regarding the life cycle of this vector.
 To establish the Hypothesis: of the present Study, ‘A NEW ECOSYSTEM OF Aedes sp. MOSQUITO’, analysis of Physicochemical and Biological parameters of Septik Tank water have been carried out at different laboratories.Total 5 nos of waste water samples have been collected and analyzed accordingly. Significant and interesting results have come out like,pH:8- 8.5, Nitrate: Below Detection Level, DO:0.7 - 1.0 (mg/L) etc.
 *Besides, Light intensity (LUX) of the covered tank is 00 so it is an APHOTIC ZONE. 
 There is no trace of light and Nitrate in the water, so no problem of Eutrophication, no algal flora have been reported.
 *It is highly helpful for easy movement for the larva and pupa of the mosquito.
 * Bacterial Floral load is excessive high [Total Coliform -255 x 102 CFU).
 * So the water is enriched with sufficient nutrition and food materials for their development.
 Only but the important factor i.e. D.O.: - 0.85 mg/L, is in danger and toxic level for a normal aquatic creature, but this HYPOXIC CONDITION is not at all any problem for larva and pupa of Mosquito (Aedes. Sp.). Because they consume aerial Oxygen from the upper surface of the water with their SIPHON and TRUMP as an adaptive measure of their life cycle.
 From the above survey and observations an inference can be drawn that highly adaptive Aedes sp. mosquitoes are successfully growing in the so called dirty but nutrition enriched water of Septic Tank
 There is a strong interaction between Aedes sp .and Septic Tank. Aedes sp. also performing the role of entomological vector silently and creating a severe community health problem all over the world.
