ABSTRACT
Studies were conducted on population dynamics of Metaphire posthuma, Lampito mauritii and Dichogaster bolaui in cultivated pedoecosystem of desert region of Rajasthan. The populations of aclitellate and clitellate M. posthuma, L. mauritii and D. bolaui were maximum in rainy season and minimum in summer season. The abundant population of these worms were found during the months of July to October. The species M. posthuma breed throughout the year except in extreme summer but L. mauritii breed twice in a year in the field. However, D. bolaui breed once in a year. Among these earthworm species D. bolaui with relative density of 44.2% was the most dominant species in cultivated land while L. mauritii and M. posthuma contributed 33.3% and 22.5% of density, respectively. The total population of earthworms showed significant positive correlation with different soil nutrients.
