Description Secondary productivity is the formation of biomass of heterotrophic organisms in units of time including biomass that is lost in a certain time unit. The Crambidae family is an insect that has aquatic larvae and will become an air insect after the larval phase. This species has the potential to become a pest for agriculture. The study was conducted in October 2019 for one month. The Crambidae family species found consists of two species, Petrophila sp. and Elophila sp. The abundance of Crambidae during the study ranged from 100 ind/m2 to 422 ind/m2. Secondary productivity was analyzed by the size frequency method. The secondary productivity of the Crambidae family in Cigambreng river waters for one month was 47.7915 g/m2/month, the biomass formed was 14.9669 g/m2 and the P/B ratio was 3.1931.
Produktivitas sekunder adalah pembentukan biomasa organisme heterotrof dalam satu satuan waktu termasuk biomassa yang hilang dalam satuan waktu tertentu. Famili Crambidae adalah serangga yang memiliki fase larva akuatik. Jenis ini berpotensi menjadi hama bagi kegiatan pertanian. Penelitian ini dilakukan di bulan Oktober 2019 selama satu bulan. Famili Crambidae yang ditemukan terdiri dari dua genus yaitu Petrophila sp. dan Elophila sp. Kelimpahan Famili Crambidae selama penelitian berkisar antara 100 ind/m2 hingga 422 ind/m2. Produktivitas sekunder famili Crambidae di sungai Cigambreng, Desa Tapos, Bogor selama satu bulan adalah 47.7915 g/m2/bulan, biomassa yang terbentuk adalah 14.9669 g/m2 dan P/B ratio sebesar 3,1931.
