Representatives of caddis flies of Integripalpia suborder in the system of environmental monitoring of the South Ural rivers

In the following paper the author tries to find a possibility to use larvae of caddis flies of Integripalpia suborder to increase a significance of bioindicator researches during environmental monitoring of the South Ural rivers. Analysis of caddis flies types constancy was carried out in 17 state water posts on the rivers flowing across the territory of South Ural from 2005 to 2016. As chemical characteristics such indexes as content in river waters of compounds of manganese, nickel and iron, oil products, phenols, ammonium nitrogen, coppers, zinc, COD, BOD₅, sulfates, chlorides, nitrite nitrogen were used. Specific combinatorial index of water impurity was used as a complex index. In total constancy evolution of 7 species of larvae of caddis flies of Integripalpia suborder was analyzed. It’s the first time the author has made a list of constant, additive and casual types of Integripalpia on the studied territory. The author has revealed significant correlative dependences between constancy of larvae of species of caddis flies with a number of hydro chemical indexes. The author has made regression models used to forecast constancy of larvae of Integripalpia suborder types depending on concentration of the pollutant containing in river waters.
