چکیده
Abstract This study aimed to chemically characterize the essential oils (EOs) of Cinnamomum zeylanicum (cinnamon) and Eremanthus erythropappus (candeia) evaluate their acaricidal activity, together with that major compounds cinnamyl acetate derivative, against Rhipicephalus microplus. Essential oil were identified through gas chromatography. The larval packet test (LPT) at concentrations ranging from 0.31 10.0 mg/mL adult immersion (AIT) between 2.5 60.0 performed. (E)-cinnamaldehyde α-bisabolol in cinnamon (86.93%) candeia (78.41%) EOs, respectively. In LPT, EOs (E)-cinnamaldehyde, resulted 100% mortality 2.5, 5.0, AIT, percentage control values > 95% observed for 60.0, 20.0, 20.0 mg/mL, respectively, whereas showed low activity. We conclude high acetylated derivative presented less activity on R. microplus engorged females.
