An infestation of the red spider mite was reported in clone seedlings of Eucalyptus grandis Hill ex Maiden under greenhouse conditions, in the municipality of Martinho Campos, Minas Gerais State. The spider mite was found on the leaf upper faces with signs of sap suction and bronzing. Such injuries caused abnormal development and plant death. The spider mite was identified as Oligonychus yothersi (McGregor) (Acari: Tetranychidae). This is the first record of O. yothersi on E. grandis seedlings in Brazil.
