Survey of container breeding mosquito larvae (Dengue vector) in Tiruchirappalli district, Tamil Nadu, India

Abstract

Dengue is currently one of the most important arboviral diseases, with 2.5 billion people living in areas of risk and many millions of cases occurring each year. A prospective study was carried out in survey of container breeding mosquito larvae and identifying the dengue vector (Aedes species) distributed throughout Tiruchirappalli district, Tamilnadu, India. Aedes mosquito larvae were collected randomly during September 2012 to March 2013 from different natural and artificial containers and the water container index (CI) was calculated. Totally 118 water containers were inspected, among which 38 containers were recorded as positive for dengue vector. The collected larvae were raised to adults for identification. The dengue vector survey reveals the presence of two dominant mosquito species namely Aedes aegypti (45%) and Aedes vittatus (45%). Our study concludes that the Aedes aegypti and Aedes vittatus was most predominant container breeding mosquito in Tiruchirappalli district. Thus the study reveals the mosquito breeding habitat identification is helpful in creating of awareness and control of mosquito borne disease like dengue.
