Conference abstracts... Mexico City, Mexico: Academic Committee ICOPA Congressc2014  aR. microplus is the main hematophagous ectoparasite of cattle in different regions of Brazil. It is the transmitter of cattle tick-borne diseases, and has caused great economic losses due to the spoliation that it causes to the host. The main control method currently used is chemical control, but a growing number of reports indicate an increase in tick populations resistant to various chemical principles present in acaricides. The molecular basis of resistance in R. microplus is not yet entirely known, but many studies indicate some mechanisms. This work aims to present an overview of ticks’ resistance to acaricides and the current situation in Brazil.  aAcaricides  aChemical control  aAcaricida  aBoophilus Microplus  aCarrapato  aControle químico  aTick-borne disease
