Influential inflicts of monsoon and agricultural practices among the population density of mosquitoes in the agro-rural villages of Madurai

Abstract

Proliferation of mosquitoes were greatly influenced by the monsoon rains and the irrigtion practices among the agrorural settlements of surrounding villages in the Samanar hills of Madurai. Nearly 31 species belonging to Aedes, Anopheles, Culex, Armigeres and Mansonia were collected. Predominant abundance of Cx. quinquefasciatus Cx. tritaeniorhynchus, Anopheles hyrcanus groups, Ae. aegypti, Ae. albopictus and Ar. subalbatus were observed. On the other hand species abundance and diversity peaked during the monsoon rains and paddy cultivating months ranging from September 2006 to January 2007 than during the summer or winter months. Henceforth monsoon oriented agricultural practices enhances the proliferation of vector mosquito and their density.
