This study was carried to know the ecological status of Aghien lagoon waterâ€™s using aquatic Insects. Insects and physicochemical variables were sampled monthly from June 2014 to MAY 2015 at eleven sampling site. Samplings were performed by the kick sampling technique and Van Veen Grab methods. A total of 7230 individuals from 68 taxa belonging to 08 orders and 46 families were identified. Diptera order was best represented with 11 families. The analysis of diversity index indicated that study site are low diversified although some physicochemical parameters presented some signs of disturbance unfavorable to insectâ€™s community proliferation. EP/C index and Chironomidae percentage showed a predominance of Chironomidae over others families of Ephemeroptera, Plecoptera, Trichoptera (EPT) groups that are pollen-sensitive organisms. These results suggest that waters of Aghien lagoon are moderately polluted and should be subject to biomonitoring.
