Abstract

Earthworm samples were collected in different fields at intervals of 25 days at 768 randomly selected locations (8 blocks x 4 villages x 4 fields x 6 sites) in the Kushinagar district of northeast Uttar Pradesh, India. A total of 18893 individuals were collected, representing 9 species, 7 genera, and 3 families. Among them, the most dominant species was Lampitomauritii (15.68%) followed by Metaphireposthuma (14.44%), Eisenia fetida (11.01%), Perionyx excavatus (10.22%), Ramiellabishambari (10.17%), Eutyphoeuswaltoni (9.87%), Eutyphoeusincommodus (9.82%), Amynthasmorrisi (9.69%), and Dichogasterbolaui(9.10%). In Kushinagar district, Megascolecidae and Acanthodrilidaeaccounted for the largest families, each representing 50.03 %and 38.96%distribution in the fields in different blocks.Lumbricidae family represents only 11.01% of distribution in the fields. Different ecological indices were calculated at all the locations and date intervals and its consequences were discussed.
