A Survey on Mosquitoe Diversity in Parangipettai Coast, Southeast Coast of Tamilnadu, India

摘要

A preliminary survey of mosquito diversity in the different habitats of the Parangipettai coast, southeast coast of India was made during March, 2007 to February, 2008, for a qualitative and quantitative assessment of mosquito distribution. Differenthabitats were selected as sampling stations; such as mangrove, estuarine and salt marsh ecosystem. Bimonthly collections were made with the Shannon trap and human bait, including diurnal, crepuscular and nocturnal period of mosquito activity. A total of337 individuals of mosquito species belonging to 3 genera, 5 families and 7 orders were collected from all the three habitats. In summer season totally 107 individuals, in rainy season 148 individuals and in winter season 82 individuals were recorded. Different statistical tools were used to know the Shannon-Weaver diversity index (2.37-2.356), Simpson's index (0.9039-0.9016), Margalef richness (2.269-2.001) and Pielou's evenness (0.9725-0.9589) of mosquitoes. The possible causes of these differences are discussed.
