This study evaluates milk producers' knowledge regarding cattle ticks and practices for controlling them. Ninety-three dairymen in Minas Gerais were interviewed. These producers had no information regarding acaricide efficiency tests. To analyze the information, open responses were categorized through "content analysis", and descriptive analysis consisting of extracting the profile highlighted by the highest frequencies. The association between schooling level and knowledge was tested by means of chi-square trend tests. It was observed that 92.3% had no knowledge of the nonparasitic period. For 96.4%, what determined the time to apply treatment was the degree of tick infestation; 93.3% used spray guns to apply the acaricide. In seeking to cross-correlate the biological and control variables with education, cooperative action, length of experience and herd size, it was found that there was a linear association between schooling level and implementation of acaricide solution preparation. The other factors didn't show any significant association. These data demonstrated the need to instruct the producers in relation to the biology and control of Rhipicephalus (Boophilus) microplus. It was concluded that the majority of milk producers were unaware of cattle tick biology and the factors that influence choosing an acaricide, which makes it difficult to implement strategic control.
本研究评估了牛奶生产商对牛蜱的了解以及控制牛蜱的做法。对米纳斯吉拉斯州的93名奶农进行了访谈。这些生产商没有关于杀螨剂效率测试的信息。为了分析这些信息，通过“内容分析”对开放式回答进行分类，并进行描述性分析，即提取出现频率最高的突出特征。通过卡方趋势检验来测试受教育程度与知识之间的关联。结果发现，92.3%的人不知道非寄生期。对于96.4%的人来说，决定治疗时间的是蜱虫感染程度；93.3%的人使用喷枪施用杀螨剂。在试图将生物学和控制变量与教育、合作行动、经验长度和牛群规模进行交叉关联时，发现受教育程度与杀螨剂溶液配制的实施之间存在线性关联。其他因素未显示出任何显著关联。这些数据表明有必要就微小牛蜱（Boophilus microplus）的生物学和控制方法对生产商进行指导。研究得出结论，大多数牛奶生产商不了解牛蜱的生物学特性以及影响选择杀螨剂的因素，这使得实施战略控制变得困难。
