In the Brazilian South Central Amazon, where the state of Rondonia is located, the dairy cattle herds are typically Infested with Rhipicephalus micro plus. These ticks cause serious problems related to reduced milk production and the pathologies transmitted by them. Objective: The aim of the study was to help dairy farmers in Rondonia reach more informed decisions on carrapaticides, based on the results of the adult Immersion test (Arr), a relatively quick test that is able to identify tick populations susceptible to different carrapaticide bases. Material and methods: Between March 2006 and October 2008, engorged female ticks were collected from 106 dairy herds in the state of Rondonia. The tests followed the method described by Drummond et al. (1973), and evaluated the active ingredients amitraz; cypermethrin, cypermethrin +dichlorvos; cypermethrin +dichlorvos+citronelal; deltamethrin, 1% fipronil and 2.46% spinosad, 1% fipronil doramectin; 1% ivermectin, 1% abamectin and 1% moxidectin. In preparing the fipronil solutions, 625 mg of technical fipronil was dissolved in 80 mL of acetone P.A. diluted in 120 mL of sterile distilled water. To evaluate the avermectin solutions, the adult females were immersed for 30 minutes in the solutions prepared as described by Sabatini et al. (2001). Results and discussion: The carrapaticides based on cypermethrin (62.23% % 6.83) and deltamethrin (67.10% % 4.70) were least effective in the AIT, while the associations of pyrethroid+organophosphate (74.08% % 4.10) and pyrethroid+ organophosphate +citronelal (78.08% % 4.10) had intermediate efficacy. The products based on amidin had higher efficacy (77.20% % 15.53) than the pyrethroid carrapaticides, but with a smaller confidence interval. In the group of macrocyclic lactones, milbemycin (99.94% % 0.51) and the spinosins (99.96% % 0.23) showed high efficacy in the AIT, as did the phenylpyrazole group (99.90% % 0.74). Conclusions: The low efficacy of the pyrethroid and amidin carrapaticides in Rondonia can be associated with the presence of R. microplus populations resistant to these molecules. All the macrocyclic lactones tested showed high efficacy and can be utilized in programs to control the R. microplus populations evaluated.
