Abstract

The objective of this study was to evaluate the acaricidal effect in vitro of the ethanolic extract of Hyptis suaveolens leaves on engorged females of Rhipicephalus sanguineus. A total of 150 engorged females ticks were collected manually from dogs naturally infested in Bom Jesus-PI, Brazil. To perform the immersion test on engorged females, 3 dilutions of the ethanolic extract were tested at concentrations of 0.1, 1.0 and 10.0%, obtained from the toxicity test against Artemia salina. Ten engorged females were used for each treatment. The tests were performed in triplicate. For the negative control, distilled water was used and, for the positive control, was used Cypermethrin. Efficacy of 29.93%, 32.71%, and 30.63%, respectively, were observed at the tested concentrations. The data obtained in this study revealed that the ethanolic extract of the leaves of H. suaveolens in the tested concentrations does not presents acaricidal activity for females of Rhipicephalus sanguineus, according to standards of the Ministry of Agriculture
