Abstract: Entomological Surveillance of Dengue is one of the important aspects of vector control. The aim of this study was to find out the occurrence and abundance of breeding of Dengue Vector (Aedes) within different types of habitats at high risk areas for dengue transmission. Larval sampling was done indoor and outdoor. West Zone of MCD is divided into 29 wards; approximately 80% area of west zone falls in west district of Delhi. Various localities were covered for sampling of immature stage of Aedes. During this study, total 28,800 containers were examined from Jan 2020 to December 2021, out of 576 positive containers was reported. Plastic Containers (35.06%), Earthen Containers (26.56%), Iron Containers (26.04%), Cemented containers (7.46%), Rubber (4.51%) and Glass (0.34%). Maximum positive plastics containers (35.06%) was observed and minimum positive containers of Glass (0.34%) was observed. Therefore, to reduce larval habitats for Aedes breeding, use of water storage containers should be discouraged and another important tool as source reduction (Elimination of water stagnated containers) for the control of Dengue disease. There are two common species identified of Dengue vectors such as Aedes aegypti and Aedes albopictus which are responsible for the transmission of Dengue disease in Delhi.
