RESUMO:

The cultivation of soybeans is a widely practiced agricultural activity in the state of Mato Grosso, as well as in various regions of Brazil. However, the expansion of agricultural production poses a threat to native habitat areas, leading to the fragmentation of ecosystems and the simplification of landscapes. It also has negative impacts on biodiversity, directly affecting ecosystem services. Insects play a crucial role in providing ecosystem services for agriculture, such as natural pest control. Considered generalist predators, beetles belonging to the families Carabidae and Staphylinidae are important predators that not only contribute to the control of arthropod pests but also play a role in suppressing weeds, as some Carabidae species feed on the seeds of these plants.In order to understand the dynamics and distribution of beetle populations in both agricultural and native environments, our study aimed to assess: i) how different habitats (native and soybean) in the Cerrado and Forest (Amazon) vegetation domains influence the community structure (richness, abundance, and composition) of predator beetle species (Carabidae and Staphylinidae); and ii) whether there are indicator species that can provide information about the dynamics and condition of the ecosystem. Our results indicate that the community structure of beetles from both families is influenced by both habitat and regional vegetation. The Carabidae family showed higher richness and abundance in soybean cultivation, while for Staphylinidae, richness and abundance were higher in the native forest environment. Indicator species for carabids in the Cerrado were Odontocheila chrysis in the native habitat and Selenophorus alternans found in the soybean environment in the Forest. For the Staphylinidae family in the Cerrado, Aleochara and Belonuchus docilis species were indicators in the soybean habitat, and Neohypnus sp3 in the native habitat. In the forest, there were only indicator species for the native environment, from the genera Neohypnus and Eulissus rutilis. These species are predators and contribute to the maintenance and balance of the environment, in addition to presenting other ecological functions. Our results show that the environmental characteristics of the studied habitats have a significant impact on the structure of beetle communities in the Carabidae and Staphylinidae families.
