Boophilus microplus populations in Mexico have developed resistance to pyrethroid acaricides. However, the extent of resistance is not known. Recent development of molecular-based resistance assays by the USDA, ARS now make it possible to investigate and locate pyrethroid-resistant populations of B. microplus. The objective of this research is to complete a detailed epidemiological study in Mexico of pyrethroid-resistant B. microplus. The data gathered will allow the USDA to better assess the risk of obtaining pyrethroid resistant B. microplus within United States territory and aid in the choice of the proper acaricde for the eradication of these populations.
