Description
Summary:This trial evaluated control practices of Anocentor nitens on equines, using spraying devices and application of acaricide paste formulation in the auricular pavilion and nasal diverticulum. The study was carried out from October 2003 to March of 2008 and the evaluations had been divided in the following stages: Phase 1--out/03 mar/04 and Phases 2, 3, 4 and 5, respectively, correspondents to the month's periods until março/08. It was used score of 0 to 3 to classify infestation levels. From abr/04 to mar/06 was implanted a schedule of acaricide sprayings every seven days and divided in two series. The first one beginning in April 2004 and the second beginning in July, both using six sprayings treatments with pyrethroid chemical base--cypermethrin 0,015%, plus topical treatments applied monthly in the auricular pavilions (powder acaricide). From abril/06 to março/08 was carried out similar schedule treatments, each two months, using an experimental acaricide paste in the auricular pavilion and nasal diverticulum. Phases 2 and 3 did not showed reduction of the parasitic loads of A. nitens compared to the control period. Whereas in Phases 4 and 5 registered significant reduction compared control period and also with the results of Phases 2 and 3, characterizing the effectiveness of the treatment with the acaricide paste formulation. Results demonstrated of A. nitens populations present in the nasal diverticulum are important in the maintenance of the infestations on equines, and necessary attention to this anatomical structure when controlling ticks.
