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

Abstract

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.
