in vitro acaricidal effect of tannin rich plants against the cattle tick rhipicephalus boophilus microplus acari ixodidae
Veterinary Parasitology, 2011Co-Authors: A Fernandezsalas, Miguel Angel Alonsodiaz, R Acostarodriguez, J F J Torresacosta, C A Sandovalcastro, R I RodriguezvivasAbstract:Abstract The objectives of this study were to evaluate the in vitro acaricidal effects of lyophilized extracts of four tannin rich plants (Acacia pennatula, Piscidia piscipula, Leucaena leucocephala and Lysiloma latisiliquum) against diverse stages of Rhipicephalus (Boophilus) microplus, and to asses whether tannins were involved in the acaricidal effect using polyethylene glycol (PEG) to block tannins. Larval immersion (LIT) and adult immersion (AIT) tests were used to evaluate the acaricidal effect of each of the lyophilized extracts against larval and adult stages of R. microplus respectively. Larvae and adult ticks were exposed to increasing Concentrations of each plant extract (0, 1200, 2400, 4800, 9600 and 19,200 μg ml−1) for 10 min. Larval mortality was recorded at 48 h post-incubation. Adult mortality was recorded daily over 14 days, at which point their reproductive efficiency was evaluated. PEG was added to the extracts to verify whether tannins were involved in the acaricidal effect. The effect on egg laying inhibition and larval mortality was analyzed using the GLM procedure in SAS. A Kruskal–Wallis test was used to assess the effect of PEG on LIT results. Calculation of the Lethal Concentration 50 (LC50) was performed using a probit analysis. All extracts reduced the viability of R. microplus larval stages (P 0.05). Lysiloma latisiliquum extract inhibited egg hatching of R. microplus (P

Tannin-rich plant extracts from A. pennatula, P. piscipula, L. leucocephala and L. latisiliquum showed potential acaricidal activity. Further in vivo studies are needed to confirm this finding.
