In vitro acaricide potential of the oil from andiroba seed (Carapa guianensis) was evaluated on engorged females of Anocentor nitens (n=210) and Rhipicephalus sanguineus (n=140) manually collected, from horses and dogs naturally infested, respectively. Five dilutions, 100%, 50%, 30%, 25%, and 10% of andiroba seed oil in deionized water, using tween 80 as dispersant, were employed for the engorged females immersion test. For A. nitens test, three repetitions were made with each dilution, using 10 engorged females for each treatment, and two repetitions for R. sanguineus test. Two control groups were used for each tick species, one with deionized water and another one with tween 80 and deionized water. After the tests, the females were kept in the laboratory under room temperature. Engorged female mortality and oviposition reduction were observed with infertile eggs, showing 100% of efficacy in the two species in all tested dilutions. The obtained data demonstrated the potential use of andiroba seed extract against A. nitens and R. sanguineus.
