Larvicidal Activity of Essential Oils of Apiaceae Plants Against Malaria Vector, Anopheles Stephensi

Background: Plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. The aim of this study was to evaluate the larvicidal activity of essential oils of three plants of Apiaceae family against Anophe-les stephensi, the main malaria vector in Iran. Methods: Essential oils from Heracleum persicum, Foeniculum vulgare and Coriandrum sativum seeds were hydro distil-lated, then their larvicidal activity were evaluated against laboratory-reared larvae of An. stephensi according to stan-dard method of WHO. After susceptibility test, results were analysis using Probit program.Results: Essential oils were separated from H. persicum, F. vulgare and C. sativum plants and their larvicidal activi-ties were tested. Result of this study showed that F. vulgare oil was the most effective against An. stephensi with LC50 and LC90 values of 20.10 and 44.51 ppm, respectively.Conclusion: All three plants essential oil can serve as a natural larvicide against An. stephensi. F. vulgare oil exhib-ited more larvicidal properties.
