Abstract:
The emergence of issues like non-target toxicity, drug residues and drug resistance has stressed the need to search for efective alternatives such as botanicals. Hence, the current research was aimed at the evaluation of acaricidal and repellent eficacies 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 eficacies were evaluated at five concentrations (1, 2.5, 5, 10 and 20%) of the C. verum essential oil. Diferent parameters like adult tick mortality, fecundity index, egg hatchability, oviposition reduction, reproductive estimation, product efectiveness, larval mortality and tick repellency were determined. The results indicated a dose-dependent efect of C. verum essential oil showing 20% concentration to be the most efective in view of the acaricidal and the repellent activities. Hence, this essential oil can be considered as a potential candidate for the efective control of cattle tick ( R. microplus).
