GONZALEZ SAENZ PARDO, Juan Ramón  e  HERNANDEZ ORTIZ, Rubén. Boophilus microplus: current status of acaricide resistance on the Mexican American border and its impact on commerce. Rev. mex. de cienc. pecuarias [online]. 2012, vol.3, suppl.1, pp.1-8. ISSN 2448-6698.

It addresses the importance of exports of live cattle to the United States, highlighting the business value that represents for Mexico's foreign exchange earnings by 700 billion per year for this purpose. Livestock marketing is hampered by sanitary barriers, such as tuberculosis (TB), brucellosis and ticks. A bi-national group of experts to address these issues has been formed. On the matter of ticks, a collaboration program between both countries has been established, in order to identify tick species and traceability of the quarantined cases, from the border to its origin in various Mexican states. A project was generated along the border for the eradication of Boophilus ticks in the Mexican states bordering Texas, consisting of identifying infected farms, acaricide treatment and inspection of cattle for export to the United States. The actions that both countries are doing to eradicate Boophilus ticks on the border and to prevent the arrival of cattle ticks into the export quarantine stations are discussed. The conclusion stresses the need to strengthen and improve these programs.
