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 ~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.
作为美国本土寨卡传播应对措施的一部分，南迈阿密市实施了为期 6 个月的计划，期间向一个约 170 英亩的区域释放了携带沃尔巴克氏体（Wolbachia）的 WB1 埃及伊蚊（Aedes aegypti）（L.）雄蚊。埃及伊蚊细胞内的沃尔巴克氏体细菌感染会导致早期胚胎停滞（称为细胞质不相容性[CI]）和卵孵化失败，并且已有人建议采用大量引入的方法将其作为一种潜在的控制工具。在整个释放期间，在释放区域和未接受 WB1 雄蚊释放的等效区域内监测埃及伊蚊种群。结果表明，在接收 WB1 雄蚊的区域，卵孵化率显著降低，这与 CI 的预期一致。同样，在接收 WB1 雄蚊的区域，埃及伊蚊的数量也明显减少，与未处理区域相比。观察到的种群减少和结果鼓励对 Wolbachia 生物农药方法进行更多的研究和复制，以作为一种额外的工具，与现有的控制工具相结合，用于控制这种具有重要医学意义的病媒和滋扰害虫。
