Mapping of Spatio-Temporal Distribution of Mosquito Vector Density in Sitheri Hills Using GIS Technology

Abstract

Rural remote villages located on top hills where lack of basic amenities including health and transportation facilities. Also vector control is a major task in tribal areas, because storage of water in different vessels are one of the essential practices in their lifestyle, So numbers of vector breeding sources are created by them due to poor awareness about vector borne diseases. In the present study involves mapping the spatio-temporal distribution and mosquito species in and around Sitheri hills located in Dharmapuri district of Tamil Nadu. For this study, the thematic maps like location, water storage sites, settlements, and spatio-temporal distribution of mosquitoes and potential mosquito breeding sites and its abundance map were prepared. Mosquitoes were collected from 10 villages in the study area using aspirator and resting bed net by indoor resting, outdoor landing and dusk collection for the years of 2012 and 2013. The spatio-temporal analysis was performed by the IDW interpolation techniques were used at GIS environment. The study provides information about density and spatial distribution of mosquito species record in the study area. The study concludes that the map of breeding sites and population density of mosquito vectors in Sitheri hills are essential for vector control and also useful for monitoring of Vector Borne Diseases (VBDs) in remote areas.
