ECOLOGICAL AND FAUNISTIC REVIEW OF COCCINELLIDAE (COLEOPTERA, COCCINELLIDAE) IN THE REPUBLIC OF DAGESTAN

Abstract

Aim. The aim of the study is to conduct ecological and faunal studies of coccinellidae in Dagestan as well as to consider the chorologic, trophic and phenological aspects in connection with the peculiarities of the environment.

Materials and methods. As the basis for the research we used the materials obtained by the authors from 1999 to 2016 in various parts of Dagestan. We also conducted expeditions, stationary and semi-stationary studies using traditional methods of entomological research.

Results. Inventory of coccinellidae fauna in Dagestan allowed identifying 27 species from 18 genera. It also revealed multiple and rare species. We carried out an analysis on distribution of the species in the high altitude range; identified environmental groups by biotopic preferendum: xerophyllous, mesophyll meadow-steppe, mesophyll forest, and Hygrophila and polytopic species; according to trophic adaptation: Aphidophages, Coccidophages, Mycetophages, Entomophages and Phytophages; We held a zoogeographical analysis of coccinellidae of Dagestan and according to habitat type, 8 zoogeographic groups were identified; We conducted phenological observations of the study sites, stages and timing of winter and winter dormancy, the beginning of mating, egg-laying, the duration of certain stages, the number of generations and other features.

Conclusion. This research represents the first comprehensive summary of ladybugs (Coleoptera, Coccinellidae) of Dagestan and includes the findings of the composition study, ecological and zoogeographical aspects of coccinellidae fauna of the study area.
