Abstract EN
The adult immersion test (AIT) was used to evaluate the efficacy of acaricide molecules used for control of Rhipicephalus microplus on 106 populations collected in five municipalities in the state of Rondônia in the Brazilian South Occidental Amazon region.
The analysis of the data showed that the acaricide formulations had different efficacies on the tick populations surveyed.
The synthetic pyrethroids (SPs) acaricides were the least effective (48.35–76.84%), followed by SP + organophosphate (OP) associations (68.91–81.47%) and amidine (51.35–100%).
For the macrocyclic lactones (MLs), the milbemycin (94.84–100%) was the most effective, followed by spinosad (93.21–100%) and the avermectins (81.34–100%).
The phenylpyrazole (PZ) group had similar efficacy (99.90%) to the MLs.
Therefore, SP acaricides, including associations with OP, and formulations based on amidine presented low in vitro efficacy to control the R.
microplus populations surveyed.
