Evaluation of lavender, eucalyptus and orange essential oils as alternative repellents against the Ixodes ricinus tick

Popis výsledku v původním jazyce

Essential oils are considered to be a user and environment friendly alternative of synthetic repellents. Therefore, in this study we evaluated repellent effects of three (lavender, eucalyptus and orange) essential oils, with no allergen or mutation data reported, and of DEET against adult females of Ixodes ricinus. Performed bioassay showed that repellency of all investigated non-synthetic oils decreased over time, while the effects of DEET remained relatively stable during the whole experiment. Initial repellency (after 5 minutes) of investigated samples was found to be moderate to high: 65 % (orange) to 85 % (lavender). At the end of the investigation (after 80 minutes), Lavender oil still showed the highest repellency effect of the tested oils (45%). At this point, Eucalyptus oil repelled only 15 % of ticks and orange essential oil did not show any repelling effect against ticks since the 20 minute mark. In contrast, the efficiency of DEET ranged between 95–100 % throughout the whole experiment. In conclusion, this study revealed, that tested oils act as repellents, but they could not be considered to be equal to or as stable as the synthetic DEET. Further investigation into the technology process optimization, which could lead to increasing the effectivity of essential oils, is thus needed. On the other hand, essential oils, especially lavender, showed interesting potential to become an alternative repellent for shorter outdoor activities.
