| Abstract: |
AbstractAedes aegyptiis a mosquito and vector of dengue, chikungunya and Zika virus making it a serious global health problem. We aimed to evaluate the chemical composition of the essential oil (EO) of Laurus nobilisleaves obtained at different seasons and its A. aegyptilarvicidal activity. The EO was obtained from fresh leaves by hydrodistillation. Larvicidal activity was determined by the larval immersion test. It was identified 37 EO chemical compounds and the major ones were 1,8-cineole and linalool. Seasonal variations affected EO larvicidal activity: spring LC50was 0.41 mg/mL and LC990.77 mg/mL, autumn LC50was 0.60 mg/mL and LC991.37 mg/mL, winter LC50was 0.66 mg/mL and LC993.19 mg/mL and summer LC50was 0.91 mg/mL and LC992.50 mg/mL. The EO extracted during spring showed the highest larvicidal activity on A. aegyptilarvae. Our results present a new perspective of L. nobilisEO use as a larvicidal agent. |
