“…The potential use of essential oils as fumigants to control stored grain pests has been the subject of many studies (Klingauf et al 1983;Su 1991;Shingh et al 1989;El Nahal et al 1989;Shaaya et al 1991;Sarac & Tunc 1995;Ho et al 1997;Shaaya et al 1997;Tunc et al 2000;Bouda et al 2001;Park et al 2003;Lee et al 2004). The results obtained in this study demonstrate that the essential oils tested can be used to control stored grain pests and to support further studies.…”

Toxic effects of essential plant oils in adult Sitophilus oryzae (Linnaeus) (Coleoptera, Curculionidae). Stored grains are subject to losses in quality nutritional value and in sanitation from the time they are stored to the time they are consumed. Botanical insecticides may offer an alternative solution for pest control. The objective was to test the insecticidal properties of the essential oils of Cymbopogon citratus (leaf), Zingiber officinale (root) and Mentha sp. (leaf). The efficacy of these oils was tested to control the rice weevil, S. oryzae, using hydrodistillation. Chemical analysis of the essential oils was carried out by gas chromatography. Major components of C. citratus were geranial (48%) and neral (31%), of Z. officinale were α-zingibereno (13%), geranial (16%), neral (10%) and α-farneseno (5%) and of Mentha sp. was menthol (92%). Bioassays were carried out by fumigation and topical application. In topical application assays, the essential oil of C. citratus had greater toxicity (LC50 0.027 µL mL-1) and shorter exposure time than the oils of the other two plants. After 24 h and 48 h, 70% and 100% mortality of S. oryzae occurred, respectively. In fumigation assays, essential oil of Z. officinale had a lower LC50 (1.18 µL cm-2) and 70% mortality after 24 h exposure. Therefore, we recommend the use of essential oils of C. citratus and Z. officinale to control the rice weevil S. oryzae.
Efeito tóxico de óleos essenciais de plantas medicinais em adultos de Sitophilus oryzae (Linnaeus) (Coleoptera, Curculionidae). Grãos armazenados estão sujeitos a perdas na qualidade física, sanitária e nutricional, desde sua maturação fisiológica até o momento do consumo. Uma alternativa para o manejo de pragas são os inseticidas botânicos. O presente trabalho teve como objetivo avaliar o efeito inseticida de óleos essenciais de Cymbopogon citratus (folha), Zingiber officinale (raiz) e Mentha sp. (folha), obtidos através do método de hidrodestilação,no controle de adultos do gorgulho-do-arroz, S. oryzae. A caracterização química dos compostos encontrados nos óleos essenciais foi realizada por cromatografia gasosa, sendo observados como principais componentes para C. citratus: geranial (48%) e neral (31%), para Z. officinale: 16% de geranial, 13% de α-zingibereno, 10% de neral e 5% de α-farneseno e para Mentha sp.: 92% de mentol. Os bioensaios foram realizados por aplicação tópica e fumigação. Os resultados da aplicação tópica mostraram que o óleo essencial de C. citratus apresenta maior toxicidade quando comparado à Mentha sp.e ao Z. officinale, pois apresentou uma CL50 de 0.027 µL mL-2 e um menor período de exposição, causando 70% e 100% de mortalidade de adultos de S. oryzae, respectivamente, 24 e 48 horas após dos tratamentos. Nos ensaios com fumigação, em adultos de S. oryzae, o óleo essencial de Z. officinale, apresentou a menor CL50 (1,18 µL cm-2) e o menor período de exposição, causando 70% de mortalidade em 24 horas após a aplicação dos tratamentos. Desse modo conclui-se que os óleos de...

Essential (volatile) oils of herbs and their components, products from the secondary metabolism of a plant, have many applications in folk medicine, food flavoring and preservation as well as in the fragrance and pharmaceutical industries. The antimicrobial and antioxidant properties of essential oils have been known for a long time, and a number of investigations have been conducted on their antimicrobial activities using various bacteria, viruses and fungi. [1][2][3][4][5][6] Free radicals, e.g., superoxide ions (O 2 · Ϫ ), hydroxyl radicals (OH · ) and non-free radical compounds, can be responsible for lipid peroxidation (deterioration) in foods [7][8][9] and for various diseases such as malaria, acquired immunodeficiency syndrome, heart disease, stroke, arteriosclerosis, diabetes and cancer etc. 10,11) It has been reported that some synthetic antioxidant compounds such as butylated hydroxytoluene and butylated hydroxyanisole, commonly used in processed foods, have side effects. 12,13) Therefore, investigations on identifying the natural antioxidants have become very important issue. [14][15][16][17][18][19][20][21] In this study, the leaves of Syrian oreganum (Origanum syriacum L.) were screened for their antioxidant activity as well as antimicrobial properties and chemical composition.O. syriacum is native to the eastern Mediterranean, southern Europe and western Asia, and is cultivated in many parts of the world and commonly called Syrian oreganum, bible hyssop or wild marjoram. The descriptions of O. syriacum are as follows: Subshrub to 90 cm, hirsute-tomentose. Branches to 10 pairs per stem, to 10 a lenght of cm. Leaves petiolate or subsessile (petiole to 8 mm), ovate, 5-35ϫ4-23 mm, acute or obtuse, entire or remotely serrulate or crenulate, veins raised on lower surface. Spicules in paniculate inflorescence, c. 5-25ϫ4 mm. Bracts obovate or elliptic, 2-5ϫ1.5-3.5 mm, acute or obtuse, entire or denticulate. Calyx c. 2.5 mm. Corolla 4.5-7.5 mm. Fl. 5-10. Calcareous rocks and slopes, often in partial shade, 200-2700 m. 22)The leaves of O. syriacum, a very popular Arab spice, have been used as an herbal (traditional) medicine, flavour, fragrance and for aromatherapy in the form of bath, massage, steam inhalation, and vapurization. 23,24) It is used in teas and cooked or baked foods. It has a strong oregano flavor and also is thought to be the "Hyssop" mentioned in the Bible and to have powers of spiritual purification.The essential oils from the leaves of Syrian oreganum reportedly have ovicidal, 25) bioherbicidal, 24) insecticidal, 26,27) antifungal 28) and antimycotic activities.29) The present study was undertaken to verify the chemical composition, antioxidant activities and antimicrobial activities of these oils from leaves of this plant growing in maquis in the southern part of Turkey.
