Description
Summary:[Display omitted] The objective of this study was to evaluate the acaricidal activity of the volatile oils of three species of Croton, Euphorbiaceae, against the cattle tick Rhipicephalus microplus. The volatile oils were obtained by hydrodistillation, analyzed by GC–MS and GC-FID and their acaricidal activity was evaluated by the larval packet test and adult immersion test. The volatile oils from Croton conduplicatus Kunth, Croton pulegiodorus Baill., and two different collections of Croton grewioides Baill. (CG1 and CG2) showed eucalyptol (24.09%), p-cymene (23.13%) and methyl chavicol (83.59% and 95.38%) as the major compounds, respectively. All the volatile oils tested in this study showed efficacy against larvae and engorged females of Rhipicephalus microplus. Therefore, Croton pulegiodorus volatile oil is promising for a potential acaricidal formulation because of the best activity against both stages of the cattle tick.
