Resumo

The resistance of Rhipicephalus microplus to acaricides occurs in almost all regions where it is present and treatments with chemicals are the most frequent. Therefore the monitoring of ticks is crucial to diagnose resistance at an early stage to help slow down the spread of resistance and to obtain knowledge of the distribution of acaricide resistance. The objective of the present work was to know the biological parameters of R. microplus sensitive strain to the main acaricides used. We compared the number and weight of engorged females, as well as the mass of eggs obtained the percentage of hatching and reproductive efficiency of two strains (acaricide-resistant and susceptible) of the tick R. microplus, after passage in cattle. The results showed a reduced capacity to adjust the acaricide-susceptible strain, which presented the lowest number of ticks recovered (p?0.0001), with less weight and egg mass. With respect to reproductive parameters, the ticks susceptible strain showed hatching rate eggs (p=0.0002410) and reproductive efficiency reduced when compared with those of the acaricide-resistant strain.
