The purpose of this study was to compare the efficacy of six essential oils, sour orange
(Citrus aurantium L.), ginger (Zingiber officinale Roscoe), lemongrass (Cymbopogon citratus
(DC.) Stapf.), litsea (Litsea cubeba (Lour.) Pers.) clove (Eugenia caryophyllata Thunb.), curcumin
(Curcuma longa Linn.) against cattle tick and two of the most efficiency essential oils were test on
cattle skin. The results showed that higher efficiency of 8% lemongrass essential oil was most
significant effective to inhibit the laying of female ticks in the engorged tick period, followed by
ginger oil, curcumin oil, sour orange, litsea oil and clove oil, respectively (p<0.05). And the
increased concentration of essential oil will have the effect of decreasing the oviposition index. At
a concentration of 16% essential oil, the mortality of ticks in the larva stage was found to be higher.
The essential oils 4, 8 and 16% were found 100% mortality rate of ticks. In addition, lemongrass
oil was able to reduce the number of ticks on the cattle from day 1 after spraying on cattle skin and
decreased tick number for at least 14 days compared to the control group.
