Efecto de los extractos vegetales de Jatropha curcas y Anonna muricata sobre teleoginas de la garrapata común del ganado Ripichephalus (Boophilus) microplus bajo condiciones de laboratorio

Abstract

Rhipicephalus (B.) microplus or common cattle tick is considered the most important ectoparasite of livestock. Traditional and repetitive control of this tick through the use of conventional products has become a serious problem regarding tick’s resistance. For this reason, biological control has emerged as a very promising alternative to control this tick. In the present study, an experiment was designed to assess the effect of plant extracts of J. curcas y A. muricata on Production eggs Index (IPH) and estimated reproduction (ER) of R (B) microplus under laboratory conditions. Each plant extract was assessed in five different concentrations (between 0.1 and 5%); a positive and negative control was used for comparison. Both plants showed biological activity, however, A. muricata showed significantly effect on engorged females of the cattle tick compared with J. curcas, even at lower concentrations (0.5, and 1 %). In conclusion, the results obtained indicate that A. muricata’s seed extracts are promissory to biocontrol the common cattle tick under laboratory conditions.
