Abstract: Present study was conducted to determine the effect of inorganic nitrogenous fertilizers like Urea, Muriate of Potash (MoP), Ammonium Sulphate (AM) and Complex on mortality and ovicidal action of Aedes aegypti. Each fertilizer was treated against third instar of A. aegypti. Ovicidal action and developmental duration of egg to larval stages along with physical parameters like pH, conductivity, total dissolved solid and salinity were recorded. The highest mortality of 62% was observed in Ammonium sulphate at concentration of 0.3% and 100% was observed at 0.5% concentration after 96 h of exposure. In the treatment of Complex, 100% larval mortality was observed at 0.5% concentration and next maximum of 36% larval mortality was recorded at a concentration of 0.6% after 96 h exposure. Analysis of variance, LC50 and LC90 and Tukey’s HSD DMRT test revealed a significant impact of fertilizers on survival and development of A. Aegypti. Hence the use of inorganic products for the control of mosquitoes offers economically viable method.
