Abstract

Entomofauna of river Kangsabati is poorly studied, and this study explores it at three sites- Gandhighat region (site-A), Kangsabati rail bridge region (site-B), Vidyasagar park region (site-C) of district Paschim Medinipur, near Midnapore. The sampling process was done monthly from June 2018 to 2019. This study revealed presence of three orders with eight families, and eleven genera. Laccotrephes sp. was the dominant species. The maximum of Berger-Parker Dominance index (0.53), BMWP score (39.00), ASPT score (6.56), and SIGNAL 2 (3.22) were observed. Hemiptera, Odonata and Coleoptera constituted 54, 26.3, and 19.76%, and the BMWP score indicated that both biological and water quality were moderate.
