Determination of Biting Behaviours and Peak Range of Mosquito Armigerous subalbatus in Different Sites

Biting behaviour and peak values of Armigerous subalbatus mosquitoes were observed at K. K nagar in Erode district, Tamilnadu. Armigerous subalbatus was collected from five separate locations. The Armigerous subalbatus high peak is observed from November to March. The mosquitoes Armigerous subalbatus were observed at five separate locations. A total of 178 mosquitoes were collected at the Open Dark Place site (Sewage).The minimum total number of mosquitoes seen at Open Light Place was 37. (Sewage). The total number of mosquitoes collected in the outdoors was 32. The number of Armigerous subalbatus mosquito observed in the Open Place site was 14 and the total number of mosquito recorded in the Open Place site was 8. The intensity of ambient light at sunrise and sunset indicates the peak of biting activity. The standard deviation value of the morning peak falls was reported as 06.30 0.173 at 06.30 hours in 50% value of morning time. The standard deviation value of the evening peak falls was found to be 18.30 0.223 at 18.30 hours. This study found that the rate of variation in light intensity and not fixed level or value is the critical factor, which observes the activity peak of biting mosquitoes.
