This investigation tested the in vitro acaricidal activity of essential oils and raw extracts of Juniperus communis and Origanum majorana compared with the synthetic acaricide amitraz against various stage of Hyalomma scupense cattle tick. The hydrodistilation technique was used to extract essential oils, while chem. components in the plants were obtained using solvents of increasing polarity (hexane, Et acetate and methanol). The evaluation on H. scupense was performed with the adult immersion test at concentrations ranging from 1.25 to 10 mg/mL and the larval packet test from 0.625 to 10 mg/mL. Qual. anal. of J. communis essential oil showed ¦Á-pinene (52.31%), ¦Ä 3-carene (12.77%), ¦Â-phellandrene (7.60%), 1,8 cineole (6.95%) and ¦Á-terpinenyl acetate (6.58%) as the major chem. components. O. majorana oil was mainly composed of 4-terpineol (23.05%), Cis-Thujan-4-ol (18.30%), ¦Ä-terpinene (13.61%), ¦Á-terpinene (9.16%) and sabinene (7.96%). In adult immersion test, J. communis essential oil, at 10 mg/mL concentration exhibited strong acaricidal efficacy and reproductive inhibitory effects on treated ticks (100%) than O. majorana oil (91.95%). In larval packet test, J. communis oil had 100% mortality at 10 mg/mL, 24 h of exposure, whereas O. majorana oil had 90.64% mortality of H. scupense larvae. J. communis essential oil showed greater efficacy than all tested extracts and amitraz on both female adults and larvae of H. scupense. Quant. anal. showed that J. communis methanolic extract had the greatest ability to extract such phenolic compounds, with a total phenol content of 188.17 (mg gallic acid equivalent/g dry weight) and also had the highest acaricidal activity against engorged females and larvae of H. scupense with LC50 values of 2.46 and 4.12 mg/mL, resp. The results showed that both plants, particularly J. communis considered as potential candidates for biocontrol of H. scupense in the field.
