ABSTRACT

The Rhipicephalus (Boophilus)microplus is responsible for considerable losses in Brazilian cattle. The control of such parasites has been done mainly with the use of acaricides, and the isopathy is an alternative. The objective of this work is to analyze the efficiency of the use of isopathy as an alternative tool to control the cattle tick. We used 18 cows of the European race, kept in extensive livestock system in the municipality of Canguçu, Rio Grande do Sul, Brazil. The animals were divided into control group (Lot A) and group treated with isopathy (Lot B). Mineral salt was used as a vehicle for the administration of isopathy, Lot A received mineral salt with placebo (sugar) and Lot B received mineral salt with isopathy. The animals were artificially infested with 10 thousan larvae of R. (B.)microplus , and in the days 20, 21 and 22 post-infestation engorged females were counted and collected. The ticks from each batch were randomly divided into nine groups of ten subjects each for analysis of biological parameters and subsequent calculation of the Nutritional Index and the Effectiveness Reproductive Index. For comparison of average engorged females from each group were employed ANOVA and LSD Test. The animals treated with isopathy showed a 53.4% reduction in the average number of ticks when compared with the untreated group (p = 0.001). As for biological standards, there was no statistical difference. It is concluded that the use of isopathy was able to reduce infestation of R. (B.)microplus , showing up as a promising alternative to control this ticks.
