A tick collection is defined as a sample of ticks from a single property taken within a 30-day time window. Tick samples taken from the same property but separated by >30 days are treated as distinct collections. All samples were made by USDA-APHIS at 46 properties in southern Texas. Hosts included domestic cattle (cow), stray Mexican cattle that were apprehended on the Texas side of the U.S.-Mexico border (cow^MX), and white-tailed deer (WTD). Collections were partitioned into appropriate datasets for statistical analyses, including: population assignment in STRUCTURE software (S), genetic marker validation tests (V), temporal genetic structure within single properties (T_A), temporal genetic structure within 4 km neighborhoods centered on Prop11 or Prop34 (T_B), genetic differentiation between paired collections of ticks from WTD and cattle (D), and isolation-by-distance (I).
^RCollection was highly resistant to permethrin in larval packet test (see Methods).
^aThe Rm43 collection is comprised of 15 ticks from a source pasture (Prop37) and 33 traceout ticks known to have originated from this property. The traceout ticks were intercepted within a few days of transport to Atascosa Co. (n = 5), Madison Co. (n = 10), and Nagocdoches Co. (n = 18).
^bThe Rm47 ticks were collected from 10 WTD; detailed genetic information on each infrapopulation from these 10 deer is provided in Additional file 2: Table S2.
