SUMMARY:

The objective of this study was to evaluate the in vivo efficacy of the product based on eprinomectin 2%, administered by injection, at the recommended dose for its use in cattle experimentally infested with ticks (Rhipicephalus microplus) kept in individual pens, and the ability to tick in naturally infested animals (field test). The therapeutic and residual effects against R. microplus were evaluated by counting all female ticks shed from each bovine from day D+1 to day D+23 based on the average of three consecutive counts (days D-3, D-2 and D-1) and on days D+1 to D+45, respectively. The reproductive index and viability of teleogens from day D+1 to D+45 were also evaluated. Significant differences were observed from D+1 to D+23; from D+5 to D+23. However, the product was not effective for residual action. The results showed that within the animal category studied and under the experimental conditions described, that the product based on eprinomectin 2%, administered by the injectable route, was effective for the treatment of cattle experimentally infested with ticks, presenting levels of acaricide efficacy above 95 %, for 23 days.
