CUNHA, Arildo P. Da et al. Strategic control of Amblyomma cajennense (Fabricius, 1787) (acari: ixodidae) on horses, Minas Gerais, Brazil - Part I. Rev. Bras. Parasitol. Vet. [online]. 2007, vol.16, n.4, pp.221-228. ISSN 1984-2961.

The aim of this study was to verify the efficiency of a strategic control program of Amblyomma cajennense in horses under field conditions. Acaricide treatments were applied at seven days intervals and divided in two series, the first one beginning in April 2004 (eight treatments), and the second one beginning in July 2004 (five treatments), aiming to control larvae and nymphs of the tick. A pyrethroid chemical base cypermethrin 0.015% was used for spraying the horses. There was a reduction of 44.85% in the adults infestetion of the tick in the period of October 2004 to March 2005, and 59.74%, in February and March 2005. Results showed the effectiveness of the strategic control. Important administrative and operational procedures can interfere with the practical application of this technology, and should be considered.
