Essential oils of sixteen Chinese medicinal plants were screened for fumigant toxicity against Bemisia tabaci. The essential oil of Allium sativum exhibited the strongest fumigant activity against B. tabaci with an LC50 value of 0.11 μg/l followed by the essential oils of Agastache rugosa (LC50 = 7.08 μg/l), Illicium verum (LC50 = 8.61 μg/l), Chenopodium ambrosioides (LC50 = 8.80 μg/l), and Syz...

The paper focuses on the in vitro antimicrobial activity of Lavandula angustifolia Mill. (lavender) essential oil in combination with four commercial antimicrobial agents. Stock solutions of chloramphenicol, ciprofloxacin, nystatin, and fusidic acid were tested in combination with L. angustifolia essential oil. The antimicrobial activities of the combinations were investigated against the Gram-...

The aim of this research was to determine the chemical constituents and bioactivity of the essential oil derived from Alpinia galanga (L.) Willd. rhizomes against the cigarette beetle Lasioderma serricorne (F.) (Coleoptera Anobiidae) adults. The essential oil of A. galanga obtained by hydrodistillation was investigated by gas chromatography-mass spectrometry (GC-MS). The main components of the ...

the antifungal potential of essential oils of thyme (thymus vulgaris l.), rosemary (rosmarinus officinalis l.), and laurel (laurus nobilis l.) was determined. to establish this antifungal potential, two molds related to feed spoilage, namely, aspergillus flavus and aspergillus parasiticus, were selected. the agar dilution method was employed for the determination of antifungal activities. the i...

Listeria monocytogenes is one of the major causes of infections in developing countries. In this study, chemical composition and anti-listerial effect of the essential oil of Zataria multiflora Boiss. alone and in combination with monolaurin were evaluated at different pH values (5, 6, and 7) and temperatures (5 ˚C and 30 ˚C). Chemical composition of Zataria multiflora</em...
