TITLE:

TAXONOMIC STUDY OF EDAPHIC MITES OF THE ORDER MESOSTIGMATA (ACARI) IN THE STATE OF RONDONIA

SUMMARY:

This study investigated the diversity of soil mites of the order Mesostigmata across different land-use types in the state of Rondonia, Western Amazon. Sampling was carried out between April 2023 and March 2024 in 17 localities, covering native forest, coffee plantations, and rubber tree stands. A total of 600 individuals were collected, mainly belonging to the families Rhodacaridae, Laelapidae, Ascidae, and Pachylaelapidae. Overall, four families, four genera, and eight species were identified, expanding from two to seven the number of genera known for the state. For the first time in Rondonia, the families Pachylaelapidae, Laelapidae, Rhodacaridae, and Ascidae were recorded, and three potential new species of Multidentorhodacarus were recognized. Ecological patterns revealed that Rhodacaridae species were strongly associated with native vegetation, suggesting greater sensitivity to environmental disturbance, whereas Laelapidae representatives, such as Gaeolaelaps sp.2, were predominant in agricultural habitats, indicating ecological plasticity and potential for use in biological control programs. These findings highlight the importance of expanding faunal surveys in the Amazon and provide baseline information for integrating predatory mite fauna into sustainable soil management strategies.
