Abstract:

The present study was undertaken to observe the life cycle pattern of two indigenous species of earthworms Lampito mauritii and Metaphire posthuma reared in laboratory under static conditions of temperature and moisture. A comparison was made to evaluate the best suited species for mass production in situ. Life cycles were studied by counting the numbers of cocoons, juveniles and biomass production during total life period. The average number of cocoon production, number of hatchling production and rate of hatchling success were greater by Lampito mauritii than Metaphire posthuma. Observations indicate that Lampito mauritii was better suited species among two selected species for mass cultivation and vermicomposting than Mataphire posthuma.
