ABSTRACT:In this paper, we report the larvicidal activity of essential oils from the rhizomes of Zingiber castaneum Škorničk & Q.B Nguyễn growing in Vietnam. Essential oils were obtained from the pseudo-stem by hydro distillation conducted by using Clevenger apparatus. The mortality and larvicidal effects of the essential oil on fourth-instar larvae of Aedes were evaluated by the established protocol of the World Health Organization (WHO). The rhizome oil of Z. castaneum exhibited 100% mortality towards Ae albopictus at concentration of 100 µg/mL after 24 h and 48 h test period. In addition, the essential oil displayed larvicidal activity against Ae albopictus with minimum lethal concentration LC50 values of 49.85 µg/mL and 43.93 µg/mL at 24 h and 48 h respectively.
