RESUMO:

Brazil is the largest soybean producer in the world and Mato Grosso is the most prominent state in the production of this grain. Despite technological advances, pests still pose a threat to the crop and the indiscriminate use of pesticides can have negative impacts on human health and the environment. Thus, biological control emerges as a sustainable strategy for pest control, using natural predators, such as beetles from the Carabidae and Staphylinidae families. These predatory insects play important roles in pest control. In order to understand the dynamics and distribution of coleopteran populations in different habitats, including native areas, soybean cultivation and their edges, in order to contribute to the development of more sustainable management practices, our work sought to assess whether: i) The richness, abundance and composition of beetles species are affected by different habitats (native, soybean and edge); ii) The dominant vegetation of the habitats (Cerrado and Amazonia) influences the richness, abundance and species composition of predatory beetles; and iii) Indicator species present in habitats can provide information on the dynamics and condition of the ecosystem. Our results show that the community structure of beetles of the Carabidae and Staphylinidae families is influenced by the type of habitat and by the vegetational domain of the Amazon and Cerrado The Carabidae family showed greater richness and abundance in the soybean crop and for Staphylinidae the richness and abundance were greater in the edge habitat and in the forest. Indicator species in the Cerrado for Carabidae were Selenophorus alternans in soybean and Odontocheila chrysis in native habitat. For the forest, in soybeans, Odontocheila cayennensis stands out, and in the native habitat Odontocheila chysis. For the Staphylinidae family, in the Cerrado, Belonuchus docilis in soybean and Neohypnus sp3 in native habitat are indicative. In the forest, the species Neohypnus sp1 stands out in the native habitat and Philonthus flavolimbatus in soybeans. These species are predators and contribute to the maintenance and balance of the environment, in addition to having other ecological functions. Our results show that the environmental characteristics of the studied habitats have a significant impact on the structure of beetle communities of the Carabidae and Staphylinidae families.
