Abstract: Unplanned urbanization and informal settlements create ideal breeding habitats for Aedes species. India’s rapid population growth and increased rural–urban movement has augmented the spread of dengue and resurgence of chikungunya. Ae. aegypti is the vector of arboviruses answerable for significant sicknesses like dengue, dengue hemorrhagic fever and Chikungunya. The Studies on seasonal fluctuation of Ae. aegypti were undertaken in Shahadara South, Rohini and Najafgarh. Month-wise House Index (HI), Container Index (CI) and Breteau Index (BI) of Shahdara, Rohini & Najafgarh were recorded during 2016 & 2018. The HI, CI and BI in Najafgarh (SDMC) varied from 0.0-5.39, 0.0-5.16& 0.0-9.07 respectively during 2016 and from 0.0-4.1, 0.0-9.6 and 0.0-4.3 respectively during 2018. The HI, CI and BI in Rohini (NDMC) varied from 0.0-3.1, 0.0-3.7 & 0.0-5.3 respectively during 2016 and from 0.0-4.1, 0.0-9.6 and 0.0-4.3 respectively during 2018. The HI, CI and BI in Shahadara (EDMC) varied from 0.05-4.9, 0.04-6.3 & 0.5-16.7 respectively during 2016 and from 0.0-2.6, 0.0-5.1 & 0.0-14.0 respectively during 2018.
