用500- 20，000只蜱虫B幼虫侵染先前未暴露的未处理牛。microplus，观察蜱的密度依赖性死亡率是否发生在没有获得抗性的牛上。相似比例的幼虫在不同密度下成熟，这与先前发现的对B具有获得性抗性的牛在较高密度下死亡率增加形成对比。微加。在不同的实验中，观察到幼虫成熟的比例之间存在较大差异。
Previously unexposed naive cattle were infested with 500-20,000 larvae of the tick B. microplus, to observe whether density dependent mortality of the tick occurs on cattle which have not acquired resistance. Similar proportions of larvae matured at different densities, which contrasts with previous findings of increased mortality at higher densities on cattle with acquired resistance to B. microplus. Major differences were observed between the proportion of larvae maturing in different experiments.
