Resumo
In an attempt to evaluate the effectiveness of
chlorfenvinphos and cyhalothrin against B. microplus at
the dairy area of the microregion of Goiânia, state of Goiás,
samples of Boophilus microplus engorged females were
collected from cattle in 22 farms in the region. The samples
were all submitted to the immersion test (in vitro method).
The compounds were evaluated at the concentrations of 500
ppm and 45 ppm, respectively, which correspond to the
concentrations commonly indicated by the companies to
control ticks in cattle. The results, determined by the
percentage of reproduction inhibition for engorged females,
showed that chlorfenvinphos was 100% effective, while the
effectiveness of 77,2% detected for cyhalothrin was
considered unsatisfactory to be used as an acaricide in tick
control programs.
