Geographic distribution records for the lone star tick [Amblyomma americanum (L.)] in the peer-reviewed literature are incomplete for Oklahoma, preventing accurate disease risk assessments. To address this issue and document the presence of A. americanum in available habitats throughout the state, county-scale tick records published in U.S. Department of Agriculture-Cooperative Economic Insect Reports and specimens maintained at the K.C. Emerson Entomology Museum, Oklahoma State University, were reviewed. In addition, dry ice traps and tick drags were used to collect adult and nymphal A. americanum from throughout the state. Review of published USDA reports and the local museum collection documented A. americanum in 49 total counties (35 and 35, respectively). Active surveillance efforts confirmed the presence of this tick in 50 counties from which this species had not been previously reported to be established, documenting A. americanum is established in 68 of the 77 (88.3%) counties in Oklahoma. Taken together, these data verify that A. americanum ticks are much more widespread in Oklahoma than reflected in the literature, a phenomenon likely repeated throughout the geographic range of this tick in the eastern half of North America.
同行评审文献中关于美国孤星蜱（美洲钝眼蜱，学名：Amblyomma americanum (L.)）在俄克拉荷马州的地理分布记录并不完整，这妨碍了对疾病风险的准确评估。为解决这一问题并记录该州各地适宜栖息地中美洲钝眼蜱的存在情况，我们查阅了美国农业部合作经济昆虫报告中发布的县级蜱虫记录以及俄克拉荷马州立大学K.C. 艾默生昆虫博物馆保存的标本。此外，还使用干冰诱捕器和蜱虫拖行法从该州各地收集成年和若虫期的美洲钝眼蜱。对已发布的美国农业部报告和当地博物馆藏品的审查记录显示，美洲钝眼蜱总共分布在49个县（分别为35个县和35个县）。积极的监测工作证实，在之前未报告过该物种存在的50个县发现了这种蜱虫，这表明在俄克拉荷马州77个县中的68个县（88.3%）有美洲钝眼蜱生存。综合来看，这些数据证实，美洲钝眼蜱在俄克拉荷马州的分布范围比文献中所反映的要广泛得多，这种现象可能在北美东部该蜱虫分布的整个地理区域都会出现。
