Abstract
The aim of this present study is to evaluate the seasonal variation of Aedes aegypti, the primary vector for Dengue virus, in two different localities. They are Kothankudikuppam and Tiruvetkalam in Annamalai Nagar (Town Panchayt) Chidambaram (Taluk), Cuddalore (District) Tamil Nadu, India. In this experiment, the prevalence of Ae. aegypti was detected by three types entomological indices such as house index (HI), breteau index (BI) and container index (CI). Results revealed that the highest HI and BI were recorded in Kothankudikuppam, during the pre-monsoon season (July-September, 2016) whereas highest CI was notices in pre monsoon of Tiruvetkalam. The maximum rainfall for the year 2016 also occurs during the same pre monsoon of our results when comparing to other seasons. The results obtained shows that necessary control measure can be implemented in these selected localities during the prevalence season either by individuals or the government to curb the population of Ae. aegypti and in turn reduce the dengue incidences in the same localities.
