Conteúdo: 	In this work, the compatibility of the babassu and degummed soybean oils to Typhlodromus ornatus (Acari: Phytoseiidae) was evaluated through the integration of estimates of lethal concentration (LC) with non-lethal effects of repellency and population growth rate. Concentration-mortality bioassays showed that the babassu (LC50 = 5.03 μL/cm²) and degummed soybean oils (LC50 = 4.14 μL/cm2) were approximately 19 and 28 times less toxic to T. ornatus, respectively, in comparison to its prey Aceria guerreronis (Acari: Eriophyidae). Babassu oil was not repellent to T. ornatus, but the degummed soybean oil had a repellent effect at different concentrations and times of evaluation. Additional tests showed that regardless of the concentrations of the tested vegetable oil, the growth rate of T. ornatus was always positive. From the point of view of selectivity, babassu oil was more compatible with T. ornatus as it did not present repellency. We have concluded that both evaluated vegetable oils presented low risk to T. ornatus, and they are thus indicated as a promising tool to be integrated in management programmes to control A. guerreronis in coconut plantations.
