Résumé :	The essential oils from two sources of resinous exudates of Protium bahianum obtained by hydrodistillation were analyzed by combinations of GC and GC/MS. Twenty-two and thirteen components were identified in the oils from fresh and aged resins, comprising 95.8 % and 98.6 %, of the oils, respectively. The aged resin oil contained a high percentage of oxygen-containing sesquiterpenes (85.4 %) with a high predominance of β-(Z)-santalol acetate (83.1 %). In contrast, no sesquiterpenes were detected in the fresh resin oil and it was constituted basically by monoterpenes hydrocarbons (42.4 %) and oxygen-containing monoterpenes (27.7 %), of which α-phellandrene (13.9 %) and terpinen-4-ol (7.4 %) were the major components, respectively. The acaricidal activities against Tetranychus urticae of the resin oil were also investigated. Both oils showed fumigant toxicity (mortality and fecundity), but only the aged resin oil induced repellence.
