In vivo study of a homeopathic medicine against Rhipicephalus (Boophilus) microplus in dairy cow. Repositório Alice
FIGUEIREDO, A.; FANTATTO, R. R.; AGNOLON, I. C.; LOPES, L. G.; OLIVEIRA, P. R. de; MATHIAS, M. I. C.; ALVES, T. C.; BARIONI JUNIOR, W.; CHAGAS, A. C. de S..
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...

The potential of Acmella oleracea (Jambu) extract in the control of semi-engorged Rhipicephalus sanguineus (Latreille, 1806) (Acari: Ixodidae) female ticks. Repositório Alice
OLIVEIRA, P. R. de; ANHOLETO, L. A.; RODRIGUES, R. A. F.; BECHARA, G. H.; CASTRO, K. N. de C.; MATHIAS, M. I. C..
The present study evaluated the efficacy of Acmella oleracea extract, and the susceptibility of semiengorged R. sanguineus females exposed to different concentrations of the extract, with lethal concentration 50 % (LC50) and confidence interval 95%. The ticks were mounted on Petri dishes and immersed in the different concentrations of the extract, distilled water or ethanol 50% + DMSO 1% for 5 minutes, dried and kept in BOD incubator for 7 days. The results showed the daily mortality rate among semi-engorged R. sanguineus females at different concentrations of the extract. The mortality data obtained in bioassay 2 were subjected to Probit analysis, through which a LC50 of 24,883 mg/ml (limits: 22,331 to 28,003 mg/ml) was determined, at a 95% confidence...
