Abstract
The biodiversity and their relative abundance of tree hole breeding mosquitoes occurring in four localities (Anankadu, Solakkadu, Nigayanallur and Pallakkuli) of Kolli hills in Eastern Ghats, Tamilnadu, India, were studied between Premonsoon (May-June 2013) and Post monsoon (November-December 2013) period. Six species of mosquitoes belonged to 4 genera namely Aedes aegypti, A. albopictus, Culex uniformis, Orthopodomyia anopheloides, Toxorhynchites viridibasis, and T. rutilus were found to breed in tree holes frequently. The collected samples were studied by Simpson Index ‘D’(0.2073, 0.1753) and Brillouin Index ‘HB’(1.5486, 1.6186). It is concluded that the tree hole breeding mosquitoes in Kolli hills could act as vectors for the possible outbreak of mosquito borne disease.
