Abstract

s many tick populations of Rhipicephalus (Boophilus) microplus can be resistant to drugs in the municipality of Itamaraju, Bahia, Brazil, an in vitro immersion test was carried out, from January to November 2008, in ticks from 22 dairy farms using the nine most used acaricides in the market. Fipronil had 99% efficacy, Chlorpyriphos+Cypermethrin high-cis 92%, Amitraz+Chlorpyriphos 90.7%, Diclorvos+Chlorpyriphos 81.4%, Cypermethrin+Chlorpyriphos+Citronelol 49.2%, Amitraz 49.0%, Cypermethrin+Ethion 39.9%, Deltamethrin 33.9%, Cypermethrin 21.1%. There was a range from one to five efficient acaricides (≥ 95%) in each property. The results show that there is a wrong use of acaricides by the farmers and a high degree of resistance by ticks.
