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 Anopheles stephensi, the main malaria vector in Iran.


METHODS
Essential oils from Heracleum persicum, Foeniculum vulgare and Coriandrum sativum seeds were hydro distillated, then their larvicidal activity were evaluated against laboratory-reared larvae of An. stephensi according to standard 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 activities were tested. Result of this study showed that F. vulgare oil was the most effective against An. stephensi with LC(50) and LC(90) values of 20.10 and 44.51 ppm, respectively.


CONCLUSIONS
All three plants essential oil can serve as a natural larvicide against An. stephensi. F. vulgare oil exhibited more larvicidal properties.
