作为应对美国本土寨卡病毒传播的一部分，南迈阿密市实施了为期6个月的措施，在此期间，将感染沃尔巴克氏体的WB1埃及伊蚊（L.）雄性释放到约170英亩的区域。伊蚊胞内沃尔巴克氏菌感染。埃及伊蚊引起早期胚胎停滞（称为细胞质不相容[CI]）和卵孵化失败，淹没引入被认为是潜在的控制工具。在整个发布期间，Ae。在释放区和没有接收WB1雄性释放的等效区域内监测埃及伊蚊种群。结果显示，在接收WB1雄鱼的区域，卵孵化率显著降低，这与CI的预期一致。同样，Ae。与未处理地区相比，接收WB1雄蚊的地区埃及伊蚊数量显著减少。观察到的种群减少和结果鼓励进一步开展沃尔巴克氏体生物农药防治伊蚊的工作和复制。埃及伊蚊，作为与现有控制工具相结合的额外工具，以控制这一医学上重要的病媒和讨厌的害虫。
As part of the response to autochthonous Zika transmission in the United States, the City of South Miami implemented a 6-mo period in which Wolbachia-infected WB1 Aedes aegypti (L.) males were released into an similar to 170-acre area. Intracellular Wolbachia bacteria infections in Ae. aegypti cause early embryonic arrest (known as cytoplasmic incompatibility [CI]) and egg hatch failure, and inundative introductions have been suggested as a potential control tool. Throughout the release period, the Ae. aegypti population was monitored within both the release area and an equivalent area that did not receive WB1 male releases. The results show a significant reduction in egg hatch at the area receiving WB1 males, which is consistent with expectations for CI. Similarly, the number of Ae. aegypti was significantly reduced at the area receiving WB1 males, relative to the untreated area. The observed population reduction and results encourage additional work and replication of the Wolbachia biopesticide approach against Ae. aegypti, as an additional tool to be integrated with existing control tools for the control of this medically important vector and nuisance pest.
