Résumé
The Caatinga biome is the exclusively Brazilian, occupying 11% of the entire national territory and its area is estimated at about 800,000 km2, covering 70% of the Northeast Region. The diversity of mites has already been well studied in some natural environments such as the Atlantic Forest and Cerrado However, in preserved areas of caatinga, these studies are still rare. In this way, this work aims to understand the ecological and deciduous factors in population fluctuation and the recognition of the diversity of mites in areas of Caatinga, in order to contribute with information about the relationships of these organisms in this biome. The study was carried out in three remaining areas of the Caatinga, in the following locations : i) Estação Ecológica de Aiuaba – ii) Estação Ecológica do Seridó, RN The selected areas are part of the Ecoregion called “Depressão Sertaneja Setentrional. A total of 38 mite species from 24 genera and 12 families were recorded. The present study that, despite the climatic adversity, the caatinga can present a considerable diversity of plant mites. Showing that the areas of the caatinga have similarities with each other, and when it comes to mites, they show greater fidelity to the hosts. The analyzes indicated that both the biological factors of the plants such as the degree of deciduousness and the environmental factors such as temperature and humidity of the environment are factors that work together influencing the dynamics of the mite community in semi-arid environments
