E-mail: scott.fabio@gmail.com The purpose of the study was to evaluate the efficacy of association abamectin 0.6% and fluazuron 3.0% in control of Rhipicephalus microplus in naturally infected cattle. Were selected 20 calves that were kept in paddocks, crossbreeds Gir x Dutch, distributed in the same proportion, male and female, per experimental group, composing ten animals per group. The control group animals received no treatment, while animals in the medicated group received the formulation within the association in a single dose of 600mcg of abamectin and 3 mg of fluazuron per kg of body weight by route “pour-on”. In the days +7, +14, +21, +28, +35, +42, +49, +56, +63, +70, +77, +84, +91 were performed the counting of total number of engorged females in each animal for purposes of the evaluation of acaricide effectiveness. Statistical analysis between the average engorged females recovered between the groups control and treated showed that there was a significant difference (p = 0.05) for all subsequent time taken to treatment. The test product showed acaricide effectiveness results of 96.30% for 7 days; 96.90% for day +14; 95.98% for day +21; 96.83% for 28 days; 98.32% for 35 days; 96.12% for the day 42; 96.15% for the day +49; 98.8% for 56 days; 97.18% for 63 days, 99.12% for 70 days; 97.18% for day +77; 98.04% for the day +84 and 77.50% for the day +91. The association abamectin 0.6% with fluazuron 3.0% was effective at controlling R. microplus in cattle naturally infected for up to 63 days. |
