The taxonomical analysis shows that Coleopterans from families Carabidae and Scarabaeidae are most characteristic for the studied cultures; they recorded the highest number of species. Also families Scarabaeidae, Silphidae and Trogidae were attracted by the bait, when the small rodents accidentally fallen in raps, which increased sample efficiency. Winter wheat crop had higher species diversity by comparison with the culture of alfalfa (probably due to increased soil humidity in northern zone of the republic where more precipitations than the center were recorded). Common to both cultures were 18 species of beetles (Fig. 1).

Fig. 1: Taxonomic structure of coleopterans families from alfalfa and winter wheat crops

According to trophic regime in winter wheat crops were emphasized 21 phytophagous species, 15 predators, 4 necrophagous, 3 coprophagous and 3 mixophagous. While the culture of
