Abstract
Oligonychus yothersi (Acari: Tetranychidae) causes damage to a wide range of plants. The aim of this work was to record the occurrence of this mite species feeding on one-year-old plants of Eucalyptus urophylla in the field, describe the damages that this mite causes to plant species. This mite species was commonly found attacking E. urophylla plants in Vicosa (MG), Brazil. The observed damage was similar to that caused by herbivorous mites that feed directly on the leaf surface and cause premature falling of the attacked leaves. This fact indicates that this mite species may be a potential pest for eucalyptus plants and crops, which makes it essential to carry out further studies on this subject, especially during periods with low intensity of rainfall and humidity.
