An entomological investigation was conducted in the dengue-affected regions of Haridwar city, Uttarakhand, during the dengue transmission season. The purpose of the study was to determine the prevalence and distribution of Aedes mosquitoes and identify high-risk areas in Haridwar city for the control of dengue disease. Out of 1922 residential premises, commercial establishments, and public places only 244 localities were found positive for Aedes breeding. The House Index (HI), Container Index (CI), and Breteau Index (BI) in residential areas were 12.40, 8.08, and 20.68, respectively, while the CI in commercial and public places was 33.50. Aedes aegypti followed by Ae. albopictus and Ae. vittatus was the most dominating species and found in peri-domestic habitats. Larvae of Ae. aegypti was collected from junk materials, cemented tanks, pots, seepage water tanks, mud pots, discarded tires, tree holes, desert coolers, mani pots, plastic containers, tray of the domestic refrigerator, and flower pots. The average Man Hour Density (MHD) of Ae. aegypti, Ae. albopictus, and Ae. vittatus in residential areas were 10.77, 6.81, and 0.52, while in commercial/official areas, they were 4.75, 7.95, and 1.68. Five species of Aedes mosquitoes, namely Ae. aegypti, Ae. albopictus, Ae. vittatus, Ae. pseudotaeniatus, and Ae. thomsoni, were recorded during the study.
