ABSTRACT The objective of the present study was to determine the efficacy of cottonseed oil (CSO) against cattle tick (Rhipicephalus microplus). CSO was characterized through GC-HRMS and the acaricidal activity of CSO was evaluated through larval packet test and adult immersion test. The ticks were exposed to different concentrations 0.1, 0.5, 1.5, 2.5 5, 7.5, 10 and 12.5% of cottonseed oil. GC-HRMS analyses revealed the presence of fatty acid, vitamins, sterols, and other compounds. It was found that 10 and 12.5% concentrations of cottonseed oil were effective in killing 100% of larvae and adult ticks. It can be developed in the form of acaricidal formulation for controlling cattle tick in comparison to existing synthetic drugs.

第一份关于蜱（Acari：Ixodidae）控制棉籽油（Gossypium Sp.）活性的报告

摘要 本研究的目的是确定棉籽油 (CSO) 对牛蜱 (Rhipicephalus microplus) 的功效。CSO通过GC-HRMS表征，CSO的杀螨活性通过幼虫包试验和成虫浸泡试验评价。蜱暴露于不同浓度的棉籽油 0.1、0.5、1.5、2.5、5、7.5、10 和 12.5%。GC-HRMS 分析揭示了脂肪酸、维生素、甾醇和其他化合物的存在。发现 10% 和 12.5% 浓度的棉籽油可有效杀死 100% 的幼虫和成虫。与现有的合成药物相比，它可以以杀螨剂的形式开发，用于控制牛蜱。
