Species identification and global positioning system coordinates of infestations of cattle fever ticks, Rhipicephalus (Boophilus) annulatus (Say) and Rhipicephalus (Boophilus) microplus (Canestrini), were determined for 790 specimens submitted to the National Veterinary Services Laboratory between 1 October 1999 and 30 September 2010. Cattle fever tick specimens obtained by personnel of the United States Department of Agriculture-Animal and Plant Health Inspection Service-Cattle Fever Tick Eradication Program from infested cattle and wildlife along the Texas/ Mexico border were submitted for identification, as required by the program. A geographic information system database was developed that incorporates location, collection, and infestation records. Submitted ticks came from 11 Texas counties and were comprised of 19.5% R. (B.) annulatus and 80.5% R. (B.) microplus. Maps produced from this study locate and define the parapatric boundary between R. (B.) annulatus and R. (B.) microplus.
1999 年 10 月 1 日至 2010 年 9 月 30 日期间，共向国家兽医服务实验室提交了 790 份牛无浆体蜱，即环形泰勒焦虫（Say）和微小牛无浆体蜱（Canestrini）的侵染标本，对其进行了物种鉴定和全球定位系统坐标定位。这些侵染标本是由美国农业部动植物卫生检验署牛无浆体蜱根除计划的工作人员从德克萨斯州/墨西哥边境受侵染的牛和野生动物身上采集的，根据该计划的要求，需要对其进行鉴定。本研究开发了一个地理信息系统数据库，其中包含位置、采集和侵染记录。提交的蜱虫来自德克萨斯州的 11 个县，其中 19.5%为环形泰勒焦虫，80.5%为微小牛无浆体蜱。本研究制作的地图定位并定义了环形泰勒焦虫和微小牛无浆体蜱的邻域边界。
