Adult mosquito density high in MKB Nagar

The Chennai Corporation’s recent study of adult mosquito density has shown that MKB Nagar, Vyasarpadi, in north Chennai, is the most affected area.
Adult mosquito density is calculated by trapping mosquitoes using a suction tube. The number of mosquitoes caught in 15 minutes in one location determines the density.
MKB Nagar has an average adult mosquito density of 120 per 10 man hour days (MHD). This means that field workers were able to trap 12 mosquitoes an hour in the area. Pulianthope has a density of 80 per 10 MHD.
Flood-prone parts of Velachery also have an adult mosquito density of 80 per 10 MHD.
