Keywords:Metastigmata, Boophilus microplus, Pest control, Calves, Brazil
The experimental strategic control of the cattle-tick Boophilus microplus on calves (3/4 Holstein x 1/4 Zebu) from Viçosa was studied by the application of Amitraz, in five spraying done at 28 days intervals from October, 1990 to February, 1991. The stablishment of the strategic control system lead to a reduction in adult tick infestation of the animals, but it did not control the increase of the tick number on these animals when meteorological conditions for development of the ticks were satisfactory in the Spring of 1991.
