Ground beetles (Carabid beetles) may be found in virtually all of the world's habitats. They are one of the three most diverse families of extant beetles, with 34,275 species documented, and they serve as vital ecological markers in all environments. Edaphic living beetles catch and eat a wide variety of arthropods that live in the soil. In the case of weeds, most of the ground beetles eat their seeds and help regulate their populations. The findings of a field study in agrocenoses in South-East Kazakhstan from 2019 to 2020 are presented in this article. Twenty-seven ground beetle species from 9 genera were discovered as a consequence of the study. 670 soil traps yielded a total of 1012 beetles. Polytopic mesophilic beetles provide the foundation of the agrocenoses fauna. Hygrophils, mesophiles, and eurybionts are among the beetles found in irrigated areas, as are mixed and herbivorous species. The Carabidae family of beetles is the most numerous in fields and steppe settings. As a result, mixed-diet beetles can be found depending on the habitat and air temperature. The species of beetles in all fields in the investigation area are in accordance with the insects' complex. During the growth season, the diet of beetles shifts: predatory beetles take precedence initially, followed by mixed-diet beetles.
步甲科（Carabid beetles）几乎可以在世界上所有的栖息地中找到。它们是现存最具多样性的三大甲虫家族之一，已有 34,275 个物种被记录，并且在所有环境中都是重要的生态标志。土壤生步甲捕捉和食用生活在土壤中的各种节肢动物。对于杂草来说，大多数步甲会吃它们的种子，并帮助控制它们的数量。本文介绍了 2019 年至 2020 年在哈萨克斯坦东南部农业生态系统中进行的实地研究的结果。该研究发现了 9 个属的 27 种步甲。670 个土壤陷阱共捕获了 1012 只甲虫。多态嗜温甲虫是农业生态系统动物群的基础。在灌溉区发现了喜湿、嗜温和广温生物的步甲，还有混合和草食性物种。在田地和草原环境中，步甲科的甲虫数量最多。因此，根据栖息地和空气温度的不同，可以发现混合食性的甲虫。调查区域内所有田地中的甲虫物种都符合昆虫的复杂性。在生长季节，甲虫的饮食会发生变化：捕食性甲虫最初占主导地位，然后是混合食性甲虫。
