Abstract
The objective of this study was to determine the effect of lemongrass (Cymbopogon citratus) alcoholic extracts on the control of Boophilus microplus in naturally infested Holstein cows. Twelve animals were allocated in three groups of four animals. Group 1 was treated with amitraz at 0.025%, Group 2 was treated with lemongrass extracts at 1.36% and Group 3 with the same product at 2.72% of the plant. Engorged ticks were evaluated on animals with length superior to 4.0 mm, before (mean of days -3, -2, -1) and at 1, 2, 3, 4, 5, 6, 7 and 14 days after treatment. The mean efficacy of amitraz was 97.93%. Lemongrass extract at 2.72% reduced tick infestation by 40.3, 46.6 and 41.5% on day 3, 7 and 14 post-treatment, respectively.Entities:
