Acaricidal effects of three Labiatae essential oils extracted from ariel parts of Thymus sipyleus Boiss. subsp. sipyleus, Mentha longifolia L., and Dorystoechas hastata Boiss. & Heldr. ex Bentham on 10-day-old Rhipicephalus turanicus Pom. (Acari: Ixodidae) larvae were evaluated by using the larval packet test bioassay. Serial dilutions of the three essential oils were tested from a starting concentration of 1-0.1 % (1.0, 0.5, 0.25, and 0.1 % w/v). Results showed that all essential oils had very similar activity, producing complete mortality (100 %) in all tested concentrations on 10-day-old R. turanicus tick larvae.
