Conteúdo: 	The objective of the study was to investigate the efficacy of cypermethrin, chlorpyrifos and piperonyl butoxide based pour-on and spray acaricides for the control of Rhipicephalus microplus in a naturally infested cattle herd. Fifty eight male Brangus cattle in the rearing phase were divided into treated (28) and untreated (30) groups. The treated group was subdivided in treated with a pour-on acaricide (13) and treated with a spray acaricide (15). Every 18 days, tick counts, acaricide treatment, weighing and clinical observation were performed on the animals, totaling four evaluation time points. The adult immersion tests were used for in vitro analysis of the study population to different chemical bases was assessed for primary results. Tick counts were separately compared between groups at each time point using the Kruskal-Wallis and Wilcoxon tests. Significantly fewer number of ticks were observed on the treated group compared to control group and also on the sprayed subgroup compared to pour-on subgroup (p<0.05). Our results indicate that the chemical treatment evaluated directly affects the number of ticks parasitizing animals and that products employing a spray application method may be more effective in controlling cattle ticks.
