Larvicide activity of yeast-encapsulated orange oil against Aedes albopictus
Mosquitoes of the genus <i>Aedes</i> are important vectors for arboviruses causing diseases like dengue, Zika, chikungunya, and urban yellow fever. <i>Aedes aegypti</i> has been prioritized as the key species in the development of new control strategies. However, <i>Aedes albopictus</i> coexists with <i>Ae. aegypti</i> and can occupy its ecological niche in some scenarios. In this respect, it is important to assess the efficacy of new control tools against both mosquito species. In this report, we describe the efficacy of yeast-encapsulated orange oil (YEOO) against two lineages of <i>Ae. albopictus</i> obtained from different geographical locations in Brazil (Rio de Janeiro and Manaus). YEOO showed high larvicidal activity against both lineages of <i>Ae. albopictus</i>, with 50% lethal concentrations (LC<sub>50</sub>) of 32.9 and 33.8 mg/l, respectively. The LCs observed for <i>Ae. albopictus</i> are higher than those previously described for <i>Ae. aegypti</i>. However, the results suggest that YEOO may be an effective tool for the control of both vector species.
