The relationship between lice infestation and leather damage was investigated in a trial involving 61 cattle, half of which were treated with ectoparasiticides for lice control either in their first or second year. Hides from the lice-free and lousy calves were removed manually at an abattoir, tanned and inspected for lice-related damage, commercially referred to as light spot and/or fleck. In both the first- and second-year animals there was a significant difference between the hides of the lousy and lice-free animals, confirming that the chewing louse Bovicola bovis is a cause of winter light spot. There was also a difference between the two groups in the levels of scratch damage. After the infested animals had been treated with fenvalerate and eprinomectin to kill all the lice, the damage to the hides had not been fully reversed 13 weeks later.
在一项涉及61头牛的试验中，研究了虱子感染与皮革损伤之间的关系。其中一半牛在第一年或第二年接受了用于控制虱子的杀外寄生虫剂治疗。在屠宰场手动剥下无虱和有虱小牛的皮，进行鞣制，并检查是否有与虱子相关的损伤，商业上称为亮点和/或斑点。在第一年和第二年的动物中，有虱和无虱动物的皮革之间存在显著差异，证实咀嚼虱牛血虱是冬季亮点的一个原因。两组在刮伤损伤程度上也存在差异。在用氰戊菊酯和伊维菌素治疗受感染动物以杀死所有虱子后，13周后皮革的损伤并未完全恢复。
