Interpretive Summary: Spider mites cause severe damage to agricultural crops around the world, costing many millions of dollars annually. This short paper address the present situation on two important invasive spider mite pest species that feed on conifers and eucalyptus trees in Brazil. This study will be important to plant protection officers, extension workers, Agriculture scientists, entomologists and plant growers.

Technical Abstract: We verified infestation of Oligonychus milleri (McGregor) on plantations of Pinus caribaea (Pinaceae) and of Oligonychus ununguis (Jacobi) on plantations of Eucalyptus urophylla x Eucalyptus grandis (Myrtaceae) in State of Rondônia, Northern region of Brazil. This represents the first record of O. milleri in Brazil. Oligonychus ununguis was recorded previously, on cypress. The damage caused by these two spider mites in the plantations is described herein.
