Abstract

Mosquitoes of the genus Aedes are important vectors for arboviruses causing diseases like dengue, Zika, chikungunya, and urban yellow fever. Aedes aegypti has been prioritized as the key species in the development of new control strategies. However, Aedes albopictus coexists with Ae. aegypti 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 Ae. albopictus obtained from different geographical locations in Brazil (Rio de Janeiro and Manaus). YEOO showed high larvicidal activity against both lineages of Ae. albopictus, with 50% lethal concentrations (LC₅₀) of 32.9 and 33.8 mg/l, respectively. The LCs observed for Ae. albopictus are higher than those previously described for Ae. aegypti. However, the results suggest that YEOO may be an effective tool for the control of both vector species.

酵母包封橙油对白纹伊蚊的杀幼虫活性

伊蚊属蚊子是引起登革热、寨卡、基孔肯雅热和城市黄热病等疾病的虫媒病毒的重要媒介。在制定新的控制策略时，埃及伊蚊已被优先列为关键物种。白纹伊蚊与白纹伊蚊共存。在某些情况下，埃及伊蚊可以占据其生态位。在这方面，重要的是评估新的控制工具对这两种蚊子的效果。在这篇报道中，我们描述了酵母包封橙油（YEOO）对两个菌株的效果。在巴西不同地理位置（巴西里约热内卢和马瑙斯）获得白纹伊蚊。YEOO对伊蚊的两个谱系均有较高的杀幼虫活性。50%致死浓度（LC50）分别为32.9 mg/l和33.8 mg/l。观察到Ae的lc。白纹伊蚊的感染率高于先前所描述的伊蚊。蚊。然而，结果表明YEOO可能是控制这两种病媒物种的有效工具。
