    • Abstract


      The influence of different concentrations of SevinR (1-naphthyl-n-methyl carbamate) a carbamate, was experimented on population ofPontoscolex corethrurus under laboratory conditions. The survivability, activity and fecundity of the worms are greatly influenced by the residue concentrations. The concentrations upto a level of 100 ppm favours the life activities of individuals whereas beyond this level the residual effect showed an adverse effect on the population.
