Foraging behaviour of the ants Anoplolepis gracilipes, Camponotous compressus, Crematogaster subnuda, Meranoplus bicolor, Monomorium pharaonis, Pheidole roberti and Tetraponera rufonigra was studied following supply of different food items in the open foraging ground with a view fo note the interactions, if any. /t is revealed that, in spite of available foods at the supplying sites Paratrechina longicornis, Pheidole roberti, Anoplolepis gracilipes and Tetraponera rufonigra are habituated to face the food-snatching operations initiated either by the foragers of the same species belonging to different colonies or by the other competing species who are very much involved in sharing the food resources from the same foraging area. Food-snatching event is associated with the abrupt and brutal attack by the snatcher ant on the ants carrying food to their nest. Thus, fighting in most cases was inevitable and many of the food—transporting ant individuals were seen injured severely. The food snatching behaviour exhibited by these ant species was not only to ensure the need of their food but also a strategy to treat the competing ant species psychologically by imposing fearful threat, as a dominant species, not to visit the said foraging ground again, in future.
