The objective was to study the spatial distribution of the mite population in the pequi trees (Caryocar brasiliense). A completely randomized design was used and evaluated the spatial distribution of mites according to the orientation of the branches; part of the canopy; part of the leaf and foliar surface. The part of canopy of the tree and the orientation of the branches did not influence the mite population in leaves and fruits. The largest amount of Histiostoma sp. was observed in the proximal part of the leaf. The surface of the leaf determined the presence of mites and a greater number of Agistemus sp., EuTetranychus sp., Tetranychus sp.1 and 2, Histiostoma sp. and Proctolaelaps sp. was observed on the abaxial surface. It is recommended as a preliminary plan for the sampling of mites in plantations of C. brasiliense to use the leaves of all parts of the tree.
