1989年，在纽约市北郊威彻斯特县阿蒙克的一个流行区，对67户居民进行了莱姆病的景观生态学研究。定义了四种主要的栖息地类型，并调查了每种类型的未成熟和成年硬蜱；在收集的1,790只硬蜱中，98.6%是1.Dammini。林木占67.3%，交错带占21.6%，观赏植物占9.1%，草坪占2%。幼虫集中在树林中，若虫和成虫广泛分布于各生境。壁虱丰度与资产大小呈正相关。面积较大(大于或等于0.5英亩)的土地更有可能有林地，因此更有可能有更多的扁虱。暗场和直接荧光显微镜检查发现，29.6%的若虫和49.7%的成虫感染了伯氏疏螺旋体。感染若虫和成虫的比例分别为36%和60%。这些数据表明，能够传播莱姆病螺旋体的扁虱的数量与郊区居住环境的景观特征有关。
The landscape ecology of Lyme disease was studied in 1989 on 67 residences in an endemic area of Armonk, Westchester County, a northern suburb of New York City. Four main habitat types were defined, and each property was surveyed for immature and adult Ixodes dammini ticks; 98.6% of 1,790 ticks collected were 1. dammini. Overall, 67.3% were collected from woods, 21.6% from ecotone (unmaintained edge), 9.1% from ornamental vegetation, and 2% from lawns. Larval ticks were concentrated in woods, but nymphs and adults were widely dispersed in all habitats. Tick abundance was positively correlated with property size. Larger properties (greater-than-or-equal-to O.5 acre) were more likely to have woodlots and, hence, more ticks. Dark-field and direct fluorescent microscopic examination of tick midgut tissues revealed that 29.6% of nymphs and 49.7% of adults were infected with Borrelia burgdorferi. Infected nymphs and adults were found on 36% and 60% of properties, respectively. These data indicate that the abundance of ticks capable of transmitting Lyme disease spirochetes is related to landscape features of the suburban residential environment.
