Abstract

This study was carried out with the objective of evaluating the acaricide and insecticide efficacy
of a formulation containing the association spot on of fipronil (6.01%) and permethrin (44.88%), in
control of Rhipicephalus sanguineus sensu lato and Ctenocephalides felis felis in experimentally infested
dogs. Were used in this study twelve beagle dogs were divided in two groups: control and treated.
The dogs were infested with 50 pairs of C. felis felis and 25 pairs of R. sanguineus for evaluation of
efficacy. Infestations were carried out on days -2, +5, +12, +19, +26, +33 for ticks and with fleas on days,
-2 + 5, +12, +19, +26, + 33, + 40, + 47 + 54. On the days, + 2, +7, +14, +21, +28, +35 the evaluations for ticks
were performed and on days, +2, +7, +14, +21, +28, + 35, + 42, + 49, + 56 for fleas. Acaricide efficacy was:
100%; 96.91%; 92.86%; 91.10%; 54.91% and 51.95% for days +2, +7, +14, +21, +28 and +35 respectively,
while pulicidal efficacy was 100% up to day +28 and 97.44% for of day +35, 97.41% for day +42, 82.87%
for day +49 and 75.00% for day +56. Based on the results obtained in this study it is possible to conclude
that the association of fipronil 6.01% and permethrin 44.88% was effective for the control of C. felis felis
and R. sanguineus in artificially infested dogs.
