The species composition and abundance of ground beetles (Coleoptera, Carabidae) were investigated on grain crop fields cultivated using low-intensity and high-intensity technologies, and on adjacent plots of natural vegetation. The community of carabid beetles was most diverse and abundant on wheat fields treated with low-intensity technology. Conversely, the community was least diverse and least abundant on corn fields using intensive cultivation technology. Analysis of potential factors influencing the species composition and abundance of carabid beetle communities in agrocenoses and adjacent natural areas revealed a high statistical significance of the cultivated crop, year of observation, and degree of anthropogenic pressure on the territory (GLZ analysis, Wald test, p<0.001 in all cases). The abundance of the beetle community in 2019 was significantly lower (Kruskal-Wallis H test, p<0.0001) than in 2020 and 2021. Interannual fluctuations in ground beetle abundance were presumably influenced by the thermal and moisture conditions of the territory. The obtained data indicate the absence of a consistently negative impact of the level of agricultural technology intensification on the community of carabid beetles in the agro-landscapes of the Western Siberian forest-steppe.
