ALVAREZ, Víctor; LOAIZA, Jorge; BONILLA, Roberto  and  BARRIOS, Mariano. Control in vitro de garrapatas (Boophilus microplus; Acari: Ixodidae) mediante extractos vegetales. Rev. biol. trop [online]. 2008, vol.56, n.1, pp.291-302. ISSN 0034-7744.

Control in vitro tick (Boophilus microplus; Acari: Ixodidae) through plant extracts. Hydro-alcohol extracts of ten tropical plants were tested by the immersion method on mature ticks (Boophilus microplus Canestrini 1887). The biological evaluation was made with raw hydro alcoholic extracts (R-OH) to determine the most promissory compounds, which later were fractioned in their polar and non-polar parts. The polar parts showed a significantly inferior effect. The species that produced the highest mortality were Zizigium aromaticum, Morus alba, Piper nigrum and the mixture of Allium sativum- Z. aromaticum (all non-polar); on oviposition: M. alba, P. nigrum and the mixture of A. sativum - Z. aromaticum (all non-polar); on eclosion: P. nigrum, Z. aromaticum, Echinacea angustiofilia, Poligonum punctatum, M. alba and the mixture of A. sativum- Z. aromaticum (all non-polar): on control percentage: P. nigrum, E. angustifolia, P. punctatum and M. alba (all non-polar, except for M. alba in which both fractions showed important activity); and finally, on the percentage of oviposition inhibition: P. nigrum, E. angustifolia, P. punctatum, Gliricidia sepium and M. alba.
