This experiment was carried out to tudy the bioacaricidal efficacy of ethanolic extract from the leaves of Hyptis suaveolens (L) Poit (Lamiaceae) against engorged females of Rhipicephalus (Boophilus) microplus. 100 engorged females of R. (B.) microplus were manually collected from a naturally infested herd. The females were subjected to the immersion test at three concentrations of the ethanolic extract: 0,1; 1,0 and 10µg/mL, with two replications in each reatment. It was ound efficacy of 10% in all concentrations. The data found in this study show that the ethanolic extract from the leaves of H. Suaveolens do not have bioacaricidal activity at the used concentrations.
