ABSTRACT
The emergence of issues like non-target toxicity, drug residues and drug resistance has stressed the need to search for effective alternatives such as botanicals. Hence, the current research was aimed at the evaluation of acaricidal and repellent efficacies of the Cinnamomum verum bark essential oil against the Rhipicephalus microplus ticks of cattle. Moreover, the C. verum essential oil was also analysed using GC-FID analysis which revealed the cinnamaldehyde as its major component. The acaricidal and the repellent efficacies were evaluated at five concentrations (1, 2.5, 5, 10 and 20%) of the C. verum essential oil. Different parameters like adult tick mortality, fecundity index, egg hatchability, oviposition reduction, reproductive estimation, product effectiveness, larval mortality and tick repellency were determined. The results indicated a dose-dependent effect of C. verum essential oil showing 20% concentration to be the most effective in view of the acaricidal and the repellent activities. Hence, this essential oil can be considered as a potential candidate for the effective control of cattle tick (R. microplus).
