چکیده
Introduction: Mosquitoes play an important role in the transmission of several human diseases such as malaria, yellow fever, dengue fever and filariasis. Using synthetic larvicides is still remains as the significant method for mosquito’s control. The aberrant use of synthetic insecticides such as organophosphorus compounds have several adverse effects on environment, toxic effects on human beings and non-target organism and also may lead to development of resistance in mosquito populations.
Materials and methods: In the current study the larvicidal properties of essential oil extracted from the aerial parts of an indigenous plant, Tanacetum persicum was evaluated against two important mosquito vectors, Anopheles stephensi and Culex quinquefasciatus. In addition, the analysis of essential oil was investigated by Gas chromatography-Mass spectrometry (GC-MS).
Results and discussion: The essential oil of T. persicum showed significant toxicity against larvae of both species. The LC50 and LC90 values against An. stephensi larvae were 61.34 and 135.81 ppm and for Cx. quinquefasciatus were 88.51 and 191.56 ppm after 24 hours, respectively.
Twenty-two constituents in the leaf essential oil of T. persicum were identified corresponding to 93.80% of the total oil. The main constituents in the T. persicum oil were L-borneol (26.4%), Chrysanthenone (16.48) and Bornyl acetate (10.68%), respectively.
The results obtained from this study suggest that the essential oil of T. persicum is promising as larvicide and could be useful in the search for new natural larvicidal compounds.
