Breeding habitats and larval indices of aedes aegypti in different socio-economic groups of Pratap Vihar Area, Ghaziabad

Abstract

Study of prevalence and distribution of Aedes aegypti mosquito was carried out in different socio-economic groups of selected localities in Partap Vihar, Ghaziabad. Knowledge regarding prevalence and distribution of Aedes aegypti mosquito is essential for appropriate interventions. This study was carried from July, 2019 to June, 2020. The study area was divided into three categories based on their socio-economic status. The three categories were High income group (HIG), Medium income group (MIG) and Low income group (LIG). A door-to-door survey was carried out to find out the Aedes breeding in all types of water filled containers present in and around houses and their premises. Immature stages of Aedes aegypti mosquitoes were collected during the larval survey and density level, was recorded using different indices. During the study it was observed that plastic containers were the most preferred breeding site for breeding of Aedes aegypti in all categories that is HIG.MIG and LIG. The house index was higher in the month of November in LIG and HIG categories and in MIG category it was highest during September month. The BI in all the localities was recorded below critical level (i.e. 20). Containers found in Low income group (LIG) were found to be contributing more to the Aedes aegypti breeding than MIG and HIG localities. The CI was observed to be higher in all the three types of categories in the month of October In the study it was concluded that sudden upsurge of dengue can be controlled by targeted interventions including sustained vector surveillance in densely populated place like Pratap Vihar.
