Abstract: Mosquitoes (Order Diptera) have been known to be vectors of various diseases. They are carriers of many pathogens (viruses, bacteria, protozoa etc) transmitting diseases in human beings like malaria, chikungunya, dengue, dengue haemorrhagic fever, lymphatic filariasis, Japanese encephalitis etc. Aedes aegypti is a world vector for dengue. It is a container breeding mosquito found in tropical countries and whose occurrence has grown dramatically throughout the world in recent decades. It is highly infectious mosquito borne disease. Gwalior has recorded high number of deaths due to dengue for last few years. We have studied the life table developmental attributes of field collected Aedes aegypti which were brought in laboratories, cultured and reared and study was carried on successive generations, so that mosquitoes ecology, growth and survival parameters, developmental attributes, fecundity and reproductive potential may be calculated for Gwalior region. The parameters like Net Reproductive Rate (Ro), Mean Generation Time (T), Intrinsic rate of increase (rm), Finite rate of increase (λ), Doubling Time (T) were calculated for Gwalior strain of Aedes aegypti adult mosquitoes. The various egg developmental parameters like egg hatching rate, larval duration, pupal duration, sex ratio etc, were also observed. This is the first study report on life table attributes study of Aedes aegypti mosqitoes from Gwalior district of Madhya Pradesh, India This study provides baseline knowledge about population dynamics studies and also in understanding dengue transmission and implementing effective control strategies under regional conditions.
