Abstract
Cattle ticks (Ixodidae) have caused serious harm to livestock raised in agriculture and animal husbandry and are responsible for severe economic losses. Although chemical products are effective and maintain productivity for a certain period of time, the excessive and uncontrolled use of these synthetic agents poses heavy health losses upon long-term use. However, the need for safer products has stimulated the search for new acaricides such as those obtained from medicinal plants. In the present study, a method based on a transdermal diffusion cell drive system (TDCS) and microwave-assisted extraction (MAE) was evaluated to compare five common Chinese herbs for cattle ticks: rhubarb (Rheum rhabarbarum), blume (Stemona japonica), clove (Syzygium aromaticum), cumin (Foeniculum vulgare), and phellodendronwere (Phellodendron). When ethanol was used as the extraction solvent, the concentration of the extract of clove was 0.45% (w/v), indicating good efficacy. These results indicate that the tested extracts exhibited acaricidal activity and could be considered potential agents for the development of alternative natural acaricides.
