报道了西半球最早记录的一种外来东亚蚊子Ochlerotatus（Finlaya）japonicas（Theobald）的标本，并沿着对康涅狄格州这种蚊子的分布和数量进行了调查。从8个县的87个地点收集了黄足金龟。它遍布全州，出现在各种自然和人工容器栖息地，包括废弃的轮胎外壳，鸟浴，木桶，陶瓷浴缸（用于浇灌动物），塑料牛奶盒，玩具，乙烯基防水油布（覆盖木桩和游泳池），河床中暴露的岩石洞，树洞，地下集水池，地表水雨水池和泉水灌溉的洼地。幼虫是特别常见的容器中的水，腐烂的树叶，藻类，在阴影和阳光照射的地区，并在岩石池栖息地沿着河床，在与Ochlerotatus atropalpus（Coquillett）。成年女性被收集在草皮草注入妊娠和CO2诱饵灯陷阱，从6月初到10月，在9月的高峰收集。通过增加CO2的人类诱饵方法收集咬人的女性，验证其以人类为食的能力。在这项研究中使用的诱卵器是无效的恢复这个物种。我们的研究结果表明，OC。1992年至1998年，日本烟草被引入康涅狄格州。因为OC的能力。japonicas传播西尼罗河病毒，由于最近在野外采集的标本中检测到这种病毒，因此引入Oc. japonicas被认为是一项重大的公共卫生发展。
The earliest documented specimen of an exotic east Asian mosquito Ochlerotatus (Finlaya) japonicas japonicus (Theobald) in the Western Hemisphere is reported along with the results of a state wide survey to determine the distribution and abundance of this mosquito in Connecticut. Ochlerotatus japonicus was collected from 87 locations in eight counties. It is established throughout the state and occurs in a variety of natural and artificial container habitats including discarded tire casings, bird baths, wooden barrels, porcelain bath tubs (used for watering animals), plastic milk cartons, toys, vinyl tarpaulins (covering wood piles and swimming pools), exposed rock holes in stream beds, tree holes, subterranean catch basins, surface water rain pools, and spring-fed depressions. Larvae were particularly common in containers with water, decaying leaves, and algae, in shaded and sunlit areas and, in rock-pool habitats along streambeds, in association with Ochlerotatus atropalpus (Coquillett). Adult females were collected in sod grass-infused gravid and CO2-baited light traps, from early June through October, with peak collections in September. Biting females were collected by human bait method augmented with CO2, verifying its capacity to feed on humans. The ovitraps used in this study were not effective for recovering this species. Our results suggest that Oc. japonicas was introduced into Connecticut between 1992 and 1998. Because of the ability of Oc. japonicas to transmit West Nile virus, and because of the recent detection of this virus in field-collected specimens, the introduction of Oc. japonicas is considered a significant public health development.
