Population dynamics of Culex quinquefasciatus filaria vector in Raipur City of Chhattisgarh State

Abstract

Indoor resting Culex quinquefasciatus were collected from 17 localities of Raipur City using aspirator tube between 06.00 and 08.00 hrs. at monthly intervals for over a period of 12 months. Mosquitoes were also collected using animal and human baits. A total of 4973 C. quinquefasciatus were collected in 176 man hours from different locations of Raipur City with a mean density of 28.26 pmh. The vector was recorded throughout the year with higher densities during the months of March (44.29 pmh), February (41.29 pmh), August (38.58 pmh) and April (37.17 pmh). The lower densities were recorded during July (17.05 pmh), September (16.82 pmh) and November (16.64 pmh). The Gudhyari and Amanaka localities recorded the highest and lowest densities of C. quinquefasciatus respectively. No significant relationship was observed between the density variation of the vector and variation in temperature and/or humidity in the study region.
