Prevalence of vector mosquitoes of major mosquito borne diseases in areas of Indira Sagar Projection Madhya Pradesh, India

Abstract

Indira Sagar Project (ISP) is one of the highly ambitious projects designed for generating electricity and providing irrigation to many parts of Madhya Pradesh. A study to assess prevalence of major mosquito vectors was carried out since Jan 2013- Dec 2014 in ISP areas mentioned as Submergence (SUB), main canal mentioned as Command (CMD), and 2 Resettlement and Rehabilitation colonies mentioned as RR colonies. Malaria vector An. culicifacies was found to be dominating species in all the study areas, An. fluviatilis was found both in SUB and CMD areas and An. stephensi was found in RR Colonies. Cx. quinquefasciatus was observed as vector of LF in all areas. As a vector of JE, Cx. vishnui was observed from SUB and Ae. aegypti as vector of dengue and chikungunya was observed from all SUB, CMD and RR colonies. Larval densities showed significant differences in SUB; t (12) = 2.53, p=.016 (SUB), for CMD; t(12)= 3.97, p=.001, and for RR; t(12)= 2.17, p=.041. Regular surveillance of disease vectors in dam specific components will help to formulate new strategies of vector control. This study reports for the first time in India a comparative study in areas affected with both, reservoir of a dam and irrigation channel.
