Conclusions In the red book of the Russian subjects included 129 species of Diptera from 29 families. The number of species varies from 1 to 41 species. Approaches to the development of regional lists of protected species assessment of the status of rarity of insects in different regions vary considerably, therefore, the composition of red adjacent areas do not overlap. For most species of Diptera, included at present in the regional Red data books there is no threat to existence at the species level. In some red books included species that do not require protection, and at the same time relic, disjunctive and endemic to the region, the species is not even included in the Appendix of the red book. Special attention should be given to species with narrow geographic ranges (endemic), an area of less than 10,000 sq. km. All endemic species should be included in the Red book. In the absence of data on limiting factors and population dynamics of in the application. The main anthropogenic factors affecting the number of separate ecological groups of Diptera is forestry, agricultural activities and mining.
