Eighteen components were identified in the oils from leaves, stems, flowers and roots, comprising 87.1%, 93.1%, 94.9%, and 96.4% of the oils, respectively. Petiveria alliacea produced an oil dominated by benzenoids and polysulphide compounds, with the principal components being benzyl alcohol (46.6% in the root oil); carvacrol (50.9% in the leaf oil, 48.3% in the stem oil and 29.7% in the flower oil); (Z)-3-hexenyl benzoate (18.6% in the leaf oil, 9.5% in the stem oil and 30.5% in the flower oil) and dibenzyl disulphide (17.6% in the leaf oil, 23.1% in the stem oil, 15.7% in the flower oil and 19.1% in the root oil). The acaricidal activities of the oils against Tetranychus urticae were also investigated. The lowest values of LC50 were observed for the flower oil (0.16 µL/L of air) and root (0.12µL/L of air), which did not differ significantly between themselves.
