Background: The survey of breeding habitats of mosquito vector is helpful while plan for vector borne diseases management programme. Our study would be useful for strategizing local mosquito management programme and learning about the insect mosquito ecology and tropical areas of South East Asian countries. Method: Diversity of mosquito fauna were studied in five various areas in and around of Lucknow District, Uttar Pradesh, in India. This study was done for twelve months (April 2018-March 2019). Three species namely Anopheles stephensi, Aedes aegypti and Culex quinquefaciatus belonging to three genera (Anopheles, Aedes and Culex) were observed during study period. Result: Total 4691 no. of larvae were assembled from collection sites, maximum no larvae in Khushal Ganj (960), minimum no larvae Alam Nagar (926), Fazullaganj (945), Matiyari (930) and Rakab Ganj (930) showed moderate abundance. Monthly deviation in diversity of mosquito fauna observed Anopheles stephensi, maximum (15.2 %) in August month and minimum (0.0%) in January month, Aedes aegypti maximum (25.2 %) presence in August and minimum (2.7%) in March month and Culex quinquefasciatus were noted higher (17.5 %) in September month. Maximum Biodiversity index was calculated (0.68) during month of February and lower (0.49) during month of January 2019.
