First report on ticks (Acari: Ixodidae) controlling activity of cottonseed oil (Gossypium Sp.)

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.
