摘要: The diversity of benthic diatoms and aquatic insects in the ecotourism areas Mea Lu Tong Ta Streams at Chiang Dao District Mai Province north Thailand were investigated during months July September 2012 January 2013, from upper, middle lower parts each stream. A total 53 taxa 46 families found. Forty-seven thirty-one found Streams, respectively. Thirty-eight twentyeight respec tively. index ranged 1.17 to 2.66, while 0 2.14. In upstream sites this study, a high abundance diatoms, such as Navicula cryptotenella , Planothidium rostratum lanceo latum insects, Caenidae Elmidae, At downstream sites, Nitzschia palea Mayamaea atomus Corixidae, Baetidae, Chironomidae, Simuliidae Hydropsy chidae,
