Comparative Study of Two Monoterpenes Effect on Rhipicephalus microplus Tick

The cattle tick Rhipicephalus microplus is one of the most important ectoparasites for livestock in tropical and subtropical areas worldwide. This hurts economy milk meat production chain. In addition, it constitutes a vector transmission Anaplasmosis Babesiosis pathogens. control R. populations mainly based on use synthetic acaricides. However, using this method presents danger to humans environment leads emergence resistant populations. situation, searching ecological effective alternatives essential. Thus, plant extracts constitute promising solution, particularly essential oils their active compounds. present study aims assess acaricidal activity two monoterpenes (Thymol 1.8 cineole) abundantly found find an alternative was determined according larval immersion test (LIT). Eight concentrations were tested R software version 4.0.3 used data analysis. Results showed 100 % mortality rates with LC50 LC90 values (0.28 0.64) (0.64 2.66) respectively, thymol cineole time 5 min. For 10 min immersion, all LC decreased monoterpenes. These findings highlight potential as managing tick.
