| [antibacterial action of essential oils extracted from madagascar plants]. | the following aromatherapy study reports the antimicrobial activity of eight malagasy essential oils by the determination of their respective m.i.c. (minimal inhibitory concentration) on enteropathogenic and spoilage bacteria strains. the aromatic plants used were taken from the labiatae family (thymus vulgaris, ocimum gratissimum), the myrtaceae family (eugenia caryophyllata, melaleuca viridiflora) and the compositae (helichrysum lavanduloides, h. bracteiferum, h. gymnocephalum, psiadia altissi ... | 1987 | 3451708 |
| chemical composition and behavioral effects of five plant essential oils on the green pea aphid acyrthosiphon pisum (harris) (homoptera: aphididae). | essential oils (eos) from schinus molle, helichrysum gymnocephalum, cedrelopsis grevei and melaleuca viridiflora, four aromatic and medicinal plants, are commonly used in folk medicine. eos were characterized by gas chromatography-mass spectrometry (gc-ms) and quantified by gas chromatography-flame ionization detection (gc-fid); then evaluated for their behavioral effects on adults of the green pea aphid acyrthosiphon pisum (harris) using a perspex four-armed olfactometer in order to test the co ... | 2017 | 28122144 |
| fumigant toxicity of plant essential oils against camptomyia corticalis (diptera: cecidomyiidae). | the toxicity of 98 plant essential oils against third instars of cecidomyiid gall midge camptomyia corticalis (loew) (diptera: cecidomyiidae) was examined using a vapor-phase mortality bioassay. results were compared with that of a conventional insecticide dichlorvos. based on 24-h lc50 values, all essential oils were less toxic than dichlorvos (lc50, 0.027 mg/cm3). the lc50 of caraway (carum carvi l.) seed, armoise (artemisia vulgaris l.), clary sage (salvia sclarea l.), oregano (origanum vulga ... | 2012 | 22928313 |
