Seasonal Prevalence of Malaria Vectors (Diptera: Culicidae) in Southern Rajasthan

Abstract

The relative abundance of Anopheline species it’s associated with different seasonal variables were conducted a study in Udaipur, Dungarpur and Banswara districts of province Rajasthan, India. Anopheline mosquitoes (n= 1113) were found during the period of July, 2018 to June, 2019. Total four Anopheline species were identified from different localities of three districts. Results revealed high relative abundance of Anopheles culicifacies (45.37%) followed by Anopheles annularis (27.85%), Anopheles stephensi (18.41%) and Anopheles fluviatilis (8.35%) respectively. The season wise highest abundance of Anopheline species was reported in the season of rainy (July to October) 38.09% and lowest in the season of winter (November to February) 29.29%. The climatic factors reveal that variations in temperatures, relative humidity and average rainfall in various seasons are mainly responsible for seasonal prevalence of Anopeline species in the study area. The results shown that the population dynamics of Anopheline vectors fluctuate with the change in geographic, demographic and climatic conditions. Results of this study suggested that there is an urgent need for correct and effective mass surveillance and proper malaria control doing to be under taken in these sensitive areas.
