Resumo

Aiming to recognize the distribution patterns of the mite fauna in soybean crops and to determine the existence of similarity in the composition of species between Cerrado fragments and these plantations, samplings were carried out in 10 areas located in Brazilian Mid-Western and Southeastern regions. Each area was comprised of one fragment of Cerrado sensu stricto and one adjacent soybean crop plantation, with simultaneous samplings carried out on both of them. From the total sampled species, 111 were recorded in the Cerrado and 25 in soybean crops. About 68 % were common in both environments and only eight were exclusively found in soybean. All the species of Phytoseiidae recorded in soybean were also found in the Cerrado. The tetranychid mite Mononychellus planki (McGregor) was the most abundant species (96.3 % of the total individuals) and the only one recorded in every sampled crop. The main occurrence of M. planki was verified in soybean crops using the transgenic cultivar ANTA 82. In general terms, it has been observed that Cerrado fragments do not shelter pest species that may attack soybean and can contribute to the increase of possible predator species in this agroecosystem.
