Community structure and diversity of chironomine midges (Chironomidae: Diptera) in the paddy fields of Murshidabad, West Bengal, India


Atanu Ghosh, Abhijit Mazumdar

Paddy fields from different rice growing areas of Murshidabad district of West Bengal, India were selected to investigate the community structure, diversity and abundance of Chironomine midges. Bimonthly sampling was done for two years constituting of four rice growing seasons. 13 species from 10 genera of Chironomidae were documented from the 3076 sampled larvae. Chironomus striatipennis (51.04%) was the most abundant species, followed by Tanytarsus fuscimarginalis (9.62%), Tanypus grandis (9.46%) and Tanypus bilobatus (8.02%). Dicrotendipes pelochloris (0.23%) was the least abundant among all the recorded species. Various diversity indices were calculated to find out dominance, species diversity, evenness and species richness of the midge larvae.
