Abstract

Insekta has biodiversity with a wide distribution throughout the world. Sampling was carried out once a week during October 2019. A total of 717 specimens of  Order Diptera were found which covered two families in the Cigambreng River. Each family obtained includes one type, Antocha sp. (Family Tipulidae.) and Krenopelopia sp. (Chironomidae). The presence of a chironomid has indicates an excessive input load (pollutant) into the waters of the Cigambreng River. In general, the highest abundance was obtained at the fourth observation, 284 ind/m2, while the lowest abundance was obtained at the second observation, which was 60 ind/m2. Secondary productivity covers P/B ratio of 3.034 /month with a production speed of 14.2458 (g/m2/month) and biomass (4.6954 g/m2).
