BITING BEHAVIOURS AND PEAK RANGE OF MOSQUITO Armigerous subalbatus IN DIFFERENT SITES

The Armigerous subalbatus mosquitoes biting behaviour and peak values were observed from different sites at K.K nagar in Erode district, Tamilnadu. Armigerous subalbatus collected in five different sites. The Armigerous subalbatus high peak is observed from November to March. The Armigerous subalbatus numbers of mosquitoes were observed from five different sites. The maximum number of total mosquitoes was recorded as 178 and collected at the site of Open Dark Place (Sewage). The minimum total number of mosquitoes was observed as 37 from Open Light Place (Sewage). In the outdoor collection of total mosquitoes was recorded as 32. The Armigerous subalbatus mosquitoes were observed in the site of Open Place was noted as 14 and in Open place total mosquitoes were recorded as 8. The peak of the biting activity is observed by the intensity of ambient light at the time of sunrise and sunset. The standard deviation value of the morning peak falls was recorded 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 noted as 18.30 ±0.223 at 18.30 hours. This noted that the rate of change in light intensity and not fixed level or value is the critical factor, which observes the activity peak of biting mosquitoes.
