Population dynamics of Aedes aegypti is investigated in thirteen towns of Karachi. The breeding stations were chalked and regularly visited four times (weekly) in each month. The stations of Orangi, Baldia, SITE, Liaquatabad, Gulshan-e-Iqbal, Korangi and Shah Faisal Colony were surveyed from December 2009 through May 2010 and stations of Lyari, Sadar, North Nazimabad, Gulberg, Keamari and Bin Qasim were surveyed from June 2010 through November 2010. The population varied more amongst stations than months. Liaquatabad was worst hit town with alarmingly high population throughout the observation period; varying little between the months by a factor of 1.087 only; lowest between the stations investigated.
