title: Identification of chemical constituents and larvicidal activity of Kelussia odoratissima Mozaffarian essential oil against two mosquito vectors Anopheles stephensi and Culex pipiens (Diptera: Culicidae).
abstract: The larvicidal activity of essential oil extracted from an indigenous plant, Kelussia odoratissima Mozaffarian was evaluated against two mosquito species, Anopheles stephensi and Culex pipiens. The chemical composition of the essential oil obtained by hydrodistillation from branch tips and leaf of this plant was determined by GC and GC/MS analysis. Forty-nine constituents were identified in the oil. The main constituents of the oil were Z-ligustilide (77.73%), 2-octen-1-ol acetate (6.27%), E-ligustilide (2.27%) and butylidene phthalide (1.97%). Five different logarithmic concentrations of essential oil were evaluated against the 4th instar larvae of An. Stephensi and Cx. pipiens. The LC(50) and LC(90) values against An. stephensi larvae were 4.88 and 9.60 ppm and for Cx. pipiens were 2.69 and 7.90 ppm, respectively. These properties suggest that K. odoratissima oil has potential source of valuable larvicidal compounds for mosquito larval control. This plant which causes high mortality at lower dose could be considered as a highly active plant. In this paper a guideline suggested for larvicidal activity of plant essential oils.
