Abstract

Ticks, particularly the Rhipicephalus which are the most prevalent and invasive affect 80 % of the cattle population worldwide. Through transmission of pathogens, tick worry and physical damage to the hides, ticks cause economic loss of billions of dollars each year with 1 billion US dollars loss per annum reported only in Latin-America. These losses can be minimized only by successful management of Rhipicephalus ticks. Various strategies like chemical control, vaccination and biological control are aimed at control of Rhipicephalus ticks. There are some serious limitations associated with them like tick resistance, drug toxicity, antigenic variations etc. In contrast to these issues related with chemical tick control, the botanicals particularly the essential oils obtained from aromatic plants of medicinal importance are eco-friendly and non-toxic to most host. In recent years, essential oils-based control of cattle ticks has gained considerable attraction of scientists all over the world as depicted from this review. A comprehensive effort has been made to critically analyze the role of essential oils in controlling Rhipicephalus ticks with particular emphasis on the mode of action of bioactive compounds both as repellents and acaricides. Furthermore, we have pointed out the most important challenges which need to be addressed for development and commercialization of an essential oil based anti-tick product.

摘要

蜱虫,特别是最普遍和最具侵袭性的璃眼蜱,影响了全球 80%的牛群。通过传播病原体、蜱虫引起的担忧以及对牛皮的物理损害,每年造成数十亿美元的经济损失,仅拉丁美洲就报告了每年 10 亿美元的损失。只有成功管理璃眼蜱才能将这些损失降到最低。各种策略,如化学控制、疫苗接种和生物控制,旨在控制璃眼蜱。这些方法存在一些严重的局限性,如蜱虫耐药性、药物毒性、抗原变异等。与化学蜱虫控制相关的这些问题相反,植物提取物,特别是从药用重要芳香植物中提取的精油,对大多数宿主无毒且环保。近年来,基于精油的牛蜱虫控制引起了全世界科学家的极大关注,正如本综述所述。我们已经做出了全面的努力来批判性地分析精油在控制璃眼蜱中的作用,特别强调了生物活性化合物作为驱避剂和杀蜱剂的作用模式。此外,我们还指出了为开发和商业化基于精油的抗蜱产品需要解决的最重要的挑战。
