Spatial distribution of R. microplus and R. annulatus samples utilized in this study. (A) Distribution of both R. microplus and R. annulatus in the tick eradication quarantine area (TEQA) and the maximum extent of the temporary preventative quarantine areas (TPQAs) from 2007–2012. (B) historical distribution of cattle fever ticks before the CFTEP, and (C) location of our study area. The blue triangles in panel C mark three livestock feed lots where traceback ticks from Starr County were transported and later eradicated in April 2008.
