The aim of this study was to evaluate the capacity of pure and nanostructured cinnamon oil to control the infestation and reproductive efficiency of Rhipicephalus microplus on dairy cows. In vitro (stage I)-engorged female ticks were immersed in concentrations of 1.0, 5.0 and 10% of cinnamon oil on its pure form, and 0.5, 1.0, and 5.0% of the nanostructured form. 10% cinnamon oil (pure form) showed 100% efficacy, whereas concentrations of 1 and 5% were 62 and 97% efficacious, respectively. Nanocapsules and nanoemulsions containing cinnamon oil at 5% showed 95 and 97% efficacy, respectively. In vivo (stage II)-16 naturally tick-infested cows were divided into four groups of four animals each: Group A was composed of dairy cows sprayed with Triton (control); Group B was composed of dairy cows sprayed with cinnamon oil in its pure form (5%), whereas groups C and D were composed of dairy cows sprayed with nanocapsules and nanoemulsions, respectively, containing cinnamon oil at 0.5%. The ticks on each animal were counted on days 0, 1, 4 and 20 after spraying. Animals sprayed with pure and nanoencapsulated cinnamon oil carried significantly fewer ticks on days 1 and 4 post-treatment and were free of ticks on day 20 post-treatment. Ticks collected from these dairy cows (24 h after application) had impaired oviposition and larval inhibition, resulting in 90.5 and 100% efficacy when using pure and nanocapsules, respectively. In conclusion, the pure and nanostructured forms of cinnamon oil interfered with tick reproduction, whereas a significant acaricidal effect was found when applied onto cattle.
