ABSTRACT
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.
Os besouros terrestres (besouros carabídeos) podem ser encontrados em praticamente todos os hábitats do mundo. Eles são uma das três famílias mais diversas de besouros existentes, com 34.275 espécies documentadas, e servem como marcadores ecológicos vitais em todos os ambientes. Os besouros vivos edáficos capturam e comem uma grande variedade de artrópodes que vivem no solo. No caso de ervas daninhas, os besouros terrestres, em sua maioria, comem sementes delas e ajudam a regular suas populações. Os resultados do estudo de campo em agrocenoses no sudeste do Cazaquistão de 2019 a 2020 são apresentados neste artigo. Foram descobertas 27 espécies de besouros terrestres de 9 gêneros como consequência do estudo. As 670 armadilhas de solo renderam um total de 1.012 besouros. Besouros mesófilos politópicos fornecem a base para a fauna de agrocenoses. Higrófilos, mesófilos e euribiontes estão entre os besouros encontrados em áreas irrigadas, assim como espécies mistas e herbívoras. Em campos e estepes, a família Carabidae de besouros é a mais numerosa. Como resultado, dependendo do hábitat e da temperatura do ar, podem ser encontrados besouros de dieta mista. As espécies de besouros em todos os campos da área de investigação estão de acordo com o complexo dos insetos. Durante a estação de crescimento, a dieta dos besouros muda: os besouros predadores têm precedência, seguidos dos besouros de dieta mista.
