description This work was performed to evaluate two different schemes of treatment with systemic biocides to control Rhipicephalus microplus in northwestern Argentina. Treatments were applied from late winter to late spring to act on the small 1st spring generation of R. microplus, precluding the rise of the larger generations of autumn. In the scheme 1, calves were treated with fluazuron on days 0 and 49, and with fipronil on day 105. In the scheme 2, calves were treated with ivermectin 3.15%, fluazuron and fipronil on days 0, 28 and 83, respectively. The number of ticks observed on control group was significantly higher than the number of ticks in the treated groups. The percentage reduction in numbers of ticks with the control scheme 1 was more than 90% during practically all study period. The treatment applied in the scheme 2 provided values of reduction higher than 90% in September, October, December, January and February, but not in November (87.49%) and March (88.78%). The results showed that both treatments schemes achieved an acceptable control level, but complementary studies are needed to determine if the R. microplus ticks detected in early autumn could increase in time to high levels.

En este trabajo se evaluaron dos esquemas de tratamientos con biocidas sistémicos para el control de Rhipicephalus microplus en el noroeste de Argentina. Los tratamientos se aplicaron desde fines del invierno a fines de la primavera para limitar el surgimiento de la generación con mayor abundancia de garrapatas en el otoño del siguiente año. En el esquema 1, los terneros fueron tratados con fluazurón los días 0 y 49, y con fipronil el dìa 105. En el esquema 2 los terneros fueron tratados con ivermectina 3,15%, fluazurón y fipronil los días 0, 28 y 83, respectivamente. El número de garrapatas sobre el grupo control fue significativamente más alto que en los grupos tratados. El porcentaje de reducción de la carga parasitaria en el esquema 1 fue superior al 90% durante casi todo el período de estudio, y en el esquema 2 los valores fueron superiores al 90% en septiembre, octubre, diciembre, enero y febrero, pero no en noviembre (87,49%) y marzo (88,78%). Los resultados indican que los dos esquemas de tratamientos proveen aceptables niveles de control, pero se necesitan estudios adicionales para determinar si son suficiente para suprimir el riesgo del surgimiento de un pico mayor de abundancia de R. microplus a mediados o fines del otoño.
