Repellent Effects of the Essential Oil of Lavendula Angustifolia Against Adults of Hyalomma Marginatum Rufipes

J S Afr Vet Assoc. 2007 Sep;78(3):149-52. doi: 10.4102/jsava.v78i3.307.


The repellent effects of the essential oil of Lavendula angustifolia on adults of Hyalomma marginatum rufipes was studied at concentrations of 5, 10 and 20% v/v. A suitable tick climbing bioassay based on the questing behaviour of ticks was used to test for repellency. High percentage repellency (range 70-100) was shown at all concentrations of the essential oil of L. angustifolia, although at 5% v/v it only persisted for the first 40 minutes compared with 120 minutes at other concentrations (10 and 20% v/v). The repellent strength of L. angustifolia compared well (P > 0.05) with that of DEET (N,N-diethyl-m-toluamide), a commercial reference repellent, for the 2-hour period of the study.
