    • Abstract


      The life fecundity tables were constructed whenAchaea janata Linnaeus reared on castor leaves in the laboratory. The net reproductive rate (Ro) was 467·57 females/female/ generation in a generation time of 37·99 days. The intrinsic rate of natural increase (rm) was 0·16l8 female/female/day. In the stable age-distribution, 99% contribution was made by immature stages.
