SURVEILLANCE OF AEDES DIVERSITY, SEASONAL PREVALENCE AND HABITAT CHARACTERIZATION IN BULANDSHAHR, UTTER PRADESH, INDIA

Abstract

Mosquitoes have the ability to spread several parasites and pathogens that cause serious diseases in both humans and animals. In order to effectively control disease and mosquito populations, analysis of mosquito diversity, prevalence and habitat characterization in any location is frequently necessary. In order to compile comprehensive first-hand data on mosquitoes, the current study was carried out in the Khurja area of the Bulandshahar district in Utter Pradesh, India. The study was carried out over a period of one year. Ladle and dipping methods were used to collect the larvae of the Aedes mosquito. 48 human habitations were selected randomly from the Bulandshahar region. The accumulated data were used to compute the monthly and seasonal Relative Abundance (RA), Per Man Hour Density (PMHD), House Index (HI) and Container Index (CI) of Aedes species. Three species from the genus Aedes including Aedes aegypti, Aedes albopictus, and Aedes vittatus identified in the Bulandshahr region. The most prevalent species was Aedes aegypti. The RA, PMHD, HI and CI were highest for Aedes aegypti (53.33%, 36.67, 44.08) followed by Aedes albopictus (28.33%, 19.49, 32.98), and Aedes vittatus (18.33%, 12.62, 15.10) and CI=12.53%. In seasonal population dynamics of Aedes species in relation to meteorological factors, only temperature and rainfall are significant variables (P<0.05) of climate that affect the density of mosquitoes in the study area, with no correlation with the relative humidity. According to the findings, there is a substantial probability of mosquito-borne disease outbreaks. There must be precautions taken because dengue fever outbreaks are frequent in the region. Interventions for prevention are necessary since the region is vulnerable to dengue fever outbreaks and other diseases spread by mosquitoes.
