Ecology of Trilophus interpunctatus Puntz., an intertidal carabid of estuary

T.K. Poddar, A. Choudhury


Trilophus interpunctatus Putz. is a predacious and regular inhabitant in the sandy intertidal belts of Sagar Island, West Bengal, India. This carabid was observed in the field during pre and postmonsoon seasons only. The occurrence of the beetles was controlled by a number of physico-chemical parameters of the environment. Rainfall and moisture were inversely related with the population whereas salinity was directly related. In estuarine conditions, actually the combined effect of these three parameters are responsible for the distribution and abundance of T. interpunctatus
