Abstract: 
Benthic macro invertebrate species are differentially sensitive to many biotic and abiotic factors in their environment. The field biotic index (Hilsenh off, 1988) is based on family level identification of water arthropods, amphipods and isopods. An interest in environmental quality is one of the major reasons for the study of aquatic insects.
The idea of using the aquatic insect community to "indicate" the degree of purity or pollution of a body of water is over half a century old. It is based on the concept of indicator organisms and tolerance levels. During 2005-2006 studies were carried out on the field biotic index of Parishan Lake in Kazeroon region (South of Iran), using aquatic insect’s fauna. A total of 38 families were collected and identified sin 30 habitat codes of Parishan Lake. Using Hilsenh off formula for biotic index (BI): where ni is the number of specimens in each taxonomic group (family), ai is the pollution tolerances core for that taxonomic group, and N is the total number of aquatic insects in sample. Aquatic insects are given a numerical pollution tolerance score (ai) ranging from 0 to 10 (Hilsenh off, 1987). The value is based on field and laboratory responses of these organisms toward organic pollution. Zero taxa are extremely intolerant of low dissolved oxygen; taxa with score of 2 through 9 are tolerant to varying degrees; taxa which can survive great amounts of pollution are scored 10. In this survey, biotic index of Parishan Lake was 5.62 and evaluation of the water quality based on the biotic index was calculated. Water quality of Parishan Lake was fair (fairly significant organic pollution) during this survey.
