Specificity of regional entomological monitoring in a northern city of European Russia

The article presents ecological characteristics of entomofauna of the city of Syktyvkar. The objectives of the study are: 1) to study the species composition of entomofauna of Syktyvkar and its trophic structure; 2) to identify different interest representatives of insects in conditions of urban landscapes; 3) to establish the influence of aspect landscape characteristics of urban-forest ecosystems on insects. Syktyvkar and the surrounding area is inhabited with 1162 species of arthropods belonging to five classes, 28 orders, a total of 202 families. Seasonal aspects of changes in the composition and ecological structure of entomological complexes is marked. A list of species of insects, which are phenological indicators of seasonal change in conditions of Syktyvkar is presented. The most abundant and well identified species of insects having phenological response to changing habitat conditions were specified. The character of seasonal changes in insects species composition in urban environment differs from that in forest biocenoses. Available data included in the nature calendar of the city contains 11 natural phenomena associated with insects. They can be taken as the basis for phenological monitoring of urban areas. It is proposed to include insect species as objects of urbo-monitoring of both the insects and the type of damage inflicted. Among the latter is the gauls formed by insects. Because insects are so numerous and easily identified as representatives of Scarabaeidae bugs, beetles, long-horned beetles, butterflies Aporia crataegi. Bird cherry ermine moths belong to the group of the anthropogenic impact resistant species. In urban-forest ecosystems there are also species of the genus Formica which indicate vulnerable habitats.
