characterization of permethrin-resistant boophilus microplus (acari: ixodidae) collected from the state of coahuila, mexico.	southern cattle ticks, boophilus microplus (canestrini) (acari: ixodidae), collected in coahuila, mexico, were determined to be resistant to permethrin. discriminating concentration (dc) tests at the lc99 and 2x the lc99 of susceptible ticks produced 0 and 0.5% mortality, respectively, for permethrin. however, measured mortalities for coumaphos and amitraz acaricides were within the expected ranges. polymerase chain reaction analysis of this strain detected a 99% frequency of homozygous resistan ...	2007	17915523
