Abstract :

Tree holes are host for a variety of organisms specially mosquitoes. Tree hole eeding mosquito survey was conducted from January 2013 to December 2013 in three different places at Kolli hills, Eastern Ghats, Tamil Nadu, India. A total of 3646 mosquito larvae, pupae and adults were collected during the survey. 11 species representing 5 genera were recorded in three stations. The mosquitoes collected were Culex uniformis (14.61), Aedesaegypti (12.86), Aedes albopictus (11.76), Orthopodomyia anopheloides (10.28), Ochlerostatus greenivarkanaranus (8.28), Culex quinquefasciatus (7.84), Aedes luteocephalus (7.40), Toxorhynchites viridibasis (7.15), Aedes stokesi (6.80), Toxorhynchites splendens (6.77) and Culex decans(6.19). The highest number of larvae, pupae, and adults were found in Solakkadu (1305), followed by Semmedu (1198) and least in Othakadai (1143). The collected mosquito diversity was studied by Simpson�s Index and Simpson�s Reciprocal Index1 / D. Most comprehensive account on bioecology, ecophysiology and ethology of the mosquitoes of the tree hole of Kolli hills has been considered as a most fundamental prerequisite for launching any attempt on the etiology of vector borne diseases prevalent in rural parts of Southern India.
