عنوان انگلیسی Chemical Composition, Larvicidal and Repellent Properties of Cionura erecta (L.) Griseb. Against Malaria Vector, Anopheles stephensi Liston (Diptera: Culicidae) Under Laboratory Conditions
چکیده انگلیسی مقاله Background: the using of plant derivatives have been suggested as alternative sources for mosquito control. Methods: The root essential oil and methanol extract of  Cionura erecta (L.) Griseb was examined under laboratory conditions for larvicidal and skin repellent activities against Anopheles stephensi . The chemical compositions of essential oils were analyzed using gas chromatography- mass spectrometry. Results: Among the five concentrations tested, the dosage of 320ppm of essential oil and 1280 ppm of methanol extract had the most toxic effect yielding 100% mortality. The LC 50 values of C. erecta for both essential oil and methanol extract were 77.30 and 250.38ppm, respectively. A total of 19 compounds amounting to 37% in roots of C . erecta were identified. The major components in root oil were Cedren-9-one (7.89%), alpha cadinol (5.67%), eugenol (4.02%) and alpha muurolene (3.58%). The protection time of 50% solution of essential oil from C. erecta against bites of An. stephensi on white rabbit was 2.28 hour and also the ED 50 and ED 90 value of the C. erecta essential oil were 10.12 and 23.01ppm respectively. Conclusion: The findings suggest that C. erecta oil is a potential source of larvicidal and repellent compounds.
