Our surveys of 1401 invasive cane toads (Rhinella marina) from the Hawaiian islands of Hawai'i, O'ahu, and Maui revealed the presence of an exotic tick, Amblyomma rotundatum. Immature and adult female ticks infested three wild adult toads at a single site in the vicinity of a zoo south of Hilo, Island of Hawai'i, Hawai'i, USA. We found no tick-infested toads on O'ahu or Maui. This tick infests cane toads in their native Neotropical range, but it was excluded from Hawai'i when the original founder toads were introduced over 80 years ago. The circumstances of our discovery suggest that A. rotundatum was independently and belatedly introduced to Hawai'i with imported zoo animals, and Hawai'i now joins Florida as the second U.S. state where this tick is established.
我们对来自夏威夷群岛的夏威夷岛、瓦胡岛和毛伊岛的1401只入侵性海蟾蜍（海蟾蜍）进行的调查发现了一种外来蜱虫——圆盾硬蜱。未成熟和成年雌性蜱虫在美国夏威夷州夏威夷岛希洛以南一家动物园附近的一个地点寄生在三只野生成年蟾蜍身上。我们在瓦胡岛或毛伊岛上没有发现有蜱虫寄生的蟾蜍。这种蜱虫在其原生新热带地区寄生海蟾蜍，但在80多年前引入最初的奠基蟾蜍时被排除在夏威夷之外。我们的发现情况表明，圆盾硬蜱是随着进口的动物园动物独立且延迟地被引入夏威夷的，夏威夷现在成为继佛罗里达州之后美国第二个有这种蜱虫生存的州。
