Preliminary sampling of earthworms in various habitats across 4 villages of Puri district of Orissa showed the prevalence of 7 different earthworm species belonging to 4 distinct families, viz. Octochaetidae, Megascolecidae, Moniligastridae and Glossoscolecidae. The worm species, Octochaetona surensis (Michaelsen), Pontoscolex corethrurus (Mueller), Drawida willsi Michaelsen, Lampito mauritii Kinberg and Octochaetona barkudensis (Stephenson) prevailed in coconut gardens in soils with slightly acidic to neutral reaction (pH: 6.1-7.2) and high organic carbon content (1.23 - 1.46 g%). D. willsi, Drawida limella and Pellogaster bengalensis were exceptionally found in coconut gardens, cultivated fields and rice fields respectively. The worm species D. willsi, O. surensis and L. mauritii were considered as superior in terms of their survival under artificial conditions in the laboratory.
