Abstract: Aedes immatures were collected from four randomly selected municipal wards viz. Rajendra Nagar, Pravirchand, Sanjay Gandhi and Santhoshi of Jagdalpur, Bastar district, Chhattisgarh State during September 2013 to August 2014, using standard collection methods in order to see the population dynamics. The higher densities i.e. House, Container and Breteau indices were recorded in the month of August as House index =1.66, CI=3.39 and September Breutau index = 2.80. A total of 267 immature mosquitoes were collected from various breeding sources and allowed to emerge into adult under laboratory conditions. Aedes mosquitoes container preference was found high in the tyre (4.8%) followed by plastic (1.86), earthen pot (1.4%), cemented tanks (1.2%) and coolers (0.0%). The emerged adult mosquitoes identified up to species level as Aedes aegypti, Aedes albopictus and Culex quinquefasciatus. There was a significant relationship observed among the seasons i.e. June month (Pre-monsoon) having zero vector occurrence while in August (Post-monsoon) shows the maximum level. Aedes aegypti, the primary vector of dengue fever was recorded throughout the year except in the month of June. The secondary vector, Aedes albopictus occurrence was higher than Aedes aegypti due to congenial climatic factors and the very similar nature of peripheral forest topography prevailing in the study areas. The Aedes aegypti and the Aedes. albopictus were observed throughout the year hence there the chance of transmission of Aedes mosquito-borne diseases are more at Jagdalpur.
Month-wise mosquito species prevalence.
