چکیده مقاله:

Background: Mosquitoes are responsible for the transmission of many pathogens and parasites and consequently serious diseases in humans. Currently, application of plant derivatives has been suggested as an alternative bio-control technique for these medically important vectors. Methods: In this study the essential oil and methanol extract of Achilleawilhelmsii were tested against late-3rd or young-4th instar larvae stages of mosquito vector,Anopheles stephensi, under laboratory condition. The larval mortality was calculated after 24 h of the exposure period. Data were subjected to Probit analysis in order to estimate the lethal concentration for 50% and 90% of mortality values. Results: Results showed that the essential oil induced 100% larval mortality of An. stephensilarvae after 24 h with a dosage of 160 ppm, However, a dosage of 320 ppm of methanol extract was required to reach 100% larval mortality.Theessential oil methanol extract exerted significant larvicidal activity with LC50 values of 39.04 and 115.73 ppm, respectively. Conclusion: Our finding suggests that A. wilhelmsii oil is a potential source and has valuable larvicidal compounds for mosquito larval control.
