The advance of agriculture on natural environments raises the need to measure the effect of human activities on them. Tenebrionidae is considered a good biological indicator for this purpose. The goal of this work was to compare the diversity and abundance of the Tenebrionidae assemblage based on their degree of adaptation to aridity in two sites with different anthropic uses. Pitfall traps were used in: Commercial crops of Vitis vinifera and Systems of Dunes, considered a natural area with low human intervention. Different indices were applied to determine the alpha and beta diversity of both environments. Comparative analyzes were carried out between the two environments for three taxa of tenebrionid species classified according to their degree of adaptation to aridity Most Highly Adapted, Highly Adapted and Less Adapted. We collected 1792 tenebrionids, grouped into five subfamilies and 22 species, with 8 new records of Tenebrionidae are reported for the central Monte of Argentina. The diversity was similar for Commercial crops and the Systems of Dunes. However, differences between environments were associated with the degree of adaptation to aridity of the different groups of species. Agricultural activity would affect the species with greater adaptation to the arid natural environment.
