Resumo:  tThe tick Rhipicephalus (Boophilus) microplus (Canestrini, 1887) (Acari: Ixodidae) causes large economiclosses to cattle breeders and its control is hampered by problems of resistance to the main commercialsynthetic acaricides and the risk of residues in animal products. Alternative controls are important for thesustainability of cattle breeding in tropical regions, principally for organic milk production. This studyevaluated the efficacy of a homeopathic preparation to control natural tick infestations. The evaluationswere conducted with 24 taurine dairy cows during 12 months. The homeopathic medicine (30 CH + Sulfur30 CH) was administered in a proportion of 1:100 (v/w) in a formulation with sugar, added to 30 kg ofmineral salt. This preparation was supplied along with concentrated feed (2 kg/animal/day). The controlgroup received the same feed mixture without the medicine. The groups were kept in separate pad-docks. Data were collected on body weight, packed cell volume and number of engorged female tickson each animal. Temperature, relative humidity and rainfall were recorded. Engorged females were col-lected from each group for in vitro comparison of reproductive parameters, and semi-engorged ticks formorpho-histological analysis. The mean results of body weight, packed cell volume and tick number werenot statistically different between the control and treated groups: 616.5 kg and 618.6 kg; 27.9% and 27.3%;and 12.19 and 13.58 ticks, respectively. In the in vitro analyses, the average weights of the ticks (0.18 and0.17 g) and eggs (0.07 and 0.06 g), larval hatching rate (70.1 and 76.6%) and reproductive efficiency index(54.3 and 60.6%) of the control and treated groups, respectively, also were not statistically different. Fur-thermore, no alteration in the ovaries was detected by microscopic analysis. Therefore, the homeopathicmedicine was ineffective to control R. (B.) microplus, although the inclusion of agro-ecological practicesmight enhance its effect of homeopathy in controlling tick infestations.
