The food of ants Coimbatore District, Tamil Nadu, as there is no consists of insects, terrestrial arthropods, excretion from adequate information pertaining on ant diversity of plants, honey dew excreted by aphids and mealy bugs, this region. The present study was carried out during secretion of the caterpillars of the family Lycaenidae, October 2018 to December 2018. We have sampled seeds of plants etc [1]. ants by employing intensive all out search method. Ants are ubiquitous in distribution and occupy almost all The sampled specimens representing 10 species terrestrial ecosystems. There are about 15000 species of belonged to 5 genera and three subfamilies. The ants (7); only 11,769 species have been described (8). most diverse subfamily was Formicinae (2 genera The family Formicidae contains 21 subfamilies, 283 with 3 species), followed by Myrmicinae (2 genera genera and about 15000 living ant species of which 633 with 5 species), followed by Dolichoderinae (1 ant species belonging to 82 genera, 13 subfamilies are genera with 2 species). The Pseudomyrmicinae and reported from India. About 226 species of ants Ponerinae family were absent. Among the sampled belonging to 63 genera and 11 subfamilies are genera, the highest number of species representation estimated from Karnataka state (9). was Camponotus species. Few ant genera as Crematogaster and Monomorium of Myrmicinae and The main aim of the present study was to conduct Camponotus of Formicinae were mostly found survey, to document the ant species diversity in the everywhere. campus of Kongunadu arts and science college, Coimbatore and prepare a partial checklist of ants in the Keyword: Key words: Ants, Myrmicinae, Formicinae study area. 1.INTRODUCTION 2.MATERIALS AND METHODS Ants are important components of ecosystems not only 2.1. study area because they constitute a great part of the animal biomass but also because they act as ecosystem Study was conducted in Kongunadu college of arts and engineers. All the known species of ants are asocial [1]. science campus which is surrounded by diverse habitat. Ant species can be used in monitoring environmental Campus is located at G.N.Mills, Coimbatore district impacts, ecosystem funding, and tools in ecological surrounded by a mosaic of concrete buildings. It is studies [2, 6, 7]. Ant species are used as excellent blessed with lush green vegetation having large trees, indicators of land management practices and shrubs, herbs and long grasses which serves as shelter restoration efforts [5, 6]. Sabu [8] estimated the diversity to the butterflies. Core area of observation was a plant of forest litter inhabiting ants along elevations in the garden which is located in the campus.

This family showed a significant difference representing three subfamilies namely Formicinae, between seasons [21] as recorded by other elsewhere. Myrmicinae and Dolichoderinae were recorded. Out of The genera tapiinoma species were founded at food the three subfamily, Myrmicinae is the most abundant availability areas. Food sources may have been having 5 species in two genera. This subfamily is widely important [21]. distributed in all geographic regions.
