Zusammenfassung:The essential oils of Protium bahianum fruit and leaves obtained through water distillation were analyzed by GC-FID and GC/MS, and their acaricidal activity was also evaluated using Tetranychus urticae as model. Twentynine components were identified in the oils. The main component of the fruit oil was α-pinene (34.0%) whereas aromadendrene (20.3%) was the major component of the leaf oil. The leaf oil exhibited a higher lethality rate with LC50 of 3.5 μL/L of air after 24 h exposure. The fruits oil showed LC50 of 9.1 mL/L of air and was repellent at 1% concentration.
