Abstract：
This study evaluated the potential repellent and acaricidal effects of 4 essential oils (clove, eucalyptus, lavender, and mint) against the Asian longhorned tick Haemaphysalis longicornis, a vector of various tick-borne diseases in medical and veterinary contexts. Selected for their potential repellent and acaricidal properties, the 4 essential oils were tested on adult and nymph H. longicornis ticks at different concentrations. The experiment assessed mortality rates and repellency, particularly during tick attachment to host skin. There was a significant increase (p<0.05) in tick mortality and repellency scores across all groups. At a 1% concentration, adult tick mortality ranged from 36% to 86%, while nymph mortality ranged from 6% to 97%. Clove oil exhibited notable efficacy, demonstrating high mortality rates of nymphs and adults. Clove oil also displayed strong repellency properties, with a repellency index of 0.05, surpassing those of mint, eucalyptus, and lavender oils. Clove oil showed the highest effectiveness in deterring nonattached adult ticks (90%) and nymphs (95%) when applied to skin. Clove oil was the most effective against adult and nymph ticks, achieving mortality rates of 86% and 97%, respectively, and led to the highest nonattachment rates when applied to skin. In conclusion, essential oils such as clove, eucalyptus, lavender, and mint oils present promising results for tick population control.
摘要：
这项研究评估了4种精油（丁香，桉树,薰衣草,和薄荷）对抗亚洲长角壁虱，医疗和兽医环境中各种蜱传疾病的媒介。因其潜在的驱虫和杀螨性能而被选中，4种精油在成年和若虫长毛蜱上进行了不同浓度的测试。实验评估了死亡率和驱避性，特别是在蜱附着于宿主皮肤期间。所有组的蜱死亡率和驱避性评分均显著增加(p<0.05)。浓度为1%时，成年蜱死亡率从36%到86%，若虫死亡率为6%至97%。丁香油表现出显著的功效，显示若虫和成人的高死亡率。丁香油也表现出很强的驱避性,驱虫指数为0.05，超过薄荷，桉树,和薰衣草油。当应用于皮肤时，丁香油在阻止未附着的成年蜱（90％）和若虫（95％）方面表现出最高的效力。丁香油对成年和若虫蜱最有效，达到86%和97%的死亡率，分别,当应用于皮肤时，导致最高的非附着率。总之,精油如丁香，桉树,薰衣草,和薄荷油为蜱种群控制提供了有希望的结果。
