The efficacy of the natural extract of Verbena officinalis L. and Ruta graveolens L. in vitro monitoring of adult tick Rhipicephalus (Boophilus) microplus was established. The extract of each plant was obtained by maceration. For testing two sizes (small and medium) of adult ticks were exposed to extracts of each plant, by immersion technique. At 24, 48, 72 and 96 h of exposure, mortality was recorded taken as 60% mortality as the effective minimum. Initial tests were conducted with pure extracts, and if efficacy detected, increased dilutions were made to establish the minimum efficiency. Tests were conducted in cool climates conditions. The extract of R. graveolens (rue), showed effectiveness in small and medium tick only with the pure extract V. officinalis (common vervain) was effective on small and medium-tick in dilution 5:10. V. officinalis showed greater efficacy and found that the best results were obtained at higher concentrations. Key words: Biological control, phytotherapy, Ruta graveolens, Verbena officinalis.
