Abstract

The efficacy of the acaricides diazinon, coumaphos and cypermethrin against Boophilus microplus was evaluated in an attempt to study the susceptibility of this ixodid tick in the dairy region of Goiânia, GO. For this study it was collected engorged female ticks in 22 farms from March until June, 1996. In a laboratory the ticks were submitted to a conventional immersion method as an in vitro test. The acaricides and the respective concentration tested were as follows: diazinon 500 ppm, coumaphos 500 ppm and cipermethrin 150 ppm. The results showed an efficacy of 94.13% for diazinon, 91.20% for coumaphos and only 69.14% for cypermethrin.

KEY-WORDS: Boophilus microplus; acaricide; cattle; organophosphorus; pyrethroids.
