The performance of alphamethrin and flumethrin treated and untreated Bonsmara cows and calves grazing in the thornveld of the Eastern Cape Province was compared over a 2 year period. The economically important tick species occurred seasonally but in insufficient numbers to achieve enzootic stability with respect to babesiosis and anaplasmosis. No differences in live mass were observed for the cows, but the untreated calves were heavier at weaning than the acaricide treated group. Markedly lower numbers of ticks occurred on the calves than on the cows. The implications of the findings are discussed in relation to planning alternative tick control strategies for the region.
在两年的时间里，对在东开普省荆棘草原放牧的经α-氯氰菊酯和氟氯氰菊酯处理及未处理的邦斯玛拉牛和小牛的表现进行了比较。具有经济重要性的蜱种季节性出现，但数量不足以在巴贝斯虫病和无浆体病方面实现地方病稳定。母牛的体重未观察到差异，但未处理的小牛在断奶时比杀螨剂处理组更重。小牛身上的蜱数量明显低于母牛。结合为该地区规划替代蜱控制策略对研究结果的影响进行了讨论。
