Abstract: The macroinvertebrates were used to indicate the quality of Mao Stream in Monpin Sub-district, Fang District, Chiang Mai Province. According to the study on the Physico-chemical parameters and biological quality aspect, it was found that the BMWP and ASPT scores indicated Mao stream to medium (fair) level. Some Physico-chemical such as water temperature and the pH value were in the regular condition of surface water criteria. The average speeds of the water were flowed by nature speed. The sedimentation was direct variation to the turbidity of the water. From this study it was found totally 1,175 macroinvertebrates which were found in three Phyla: Phylum Arthopoda, Mollusca and Annelida. And they were divided into five classes: Class Insecta, Gastropoda, Bivalvia, Malacostraca and Clitellata. These were under six orders: Order Coleoptera, Hemiptera, Diptera, Richoptera, Ephemroptera, and Odorata, and discovered in thirty-two families. The macroinvertebrates as Order Ephemeroptera, Family Baetidae was found the most, so it indicated that the water in stream was in medium condition. The first study area contained the most diversity of macroinvertebrates because it was the source of the Mao Stream. Then there was non-human activities done in this area. ASPT score could assess the water biological quality of Mao Stream to be the medium. And the biodiversity index in the first study site was found in the highest. Because this area had less interfered with human activities and it was the fertile water spring source. The evenness index in each sites were also. So it possibly caused by different seasons, agricultural activities and other human activities which they might impact to evennss of macroinvertebrates in each study site.
