内蒙古包头市牛场寄生蜱的调查

蜱类刺吸家畜的血液,除了传播多种病原体外,还会引起牛的产奶量、产肉量下降。调查内蒙古包头地区17家牛场蜱虫的感染情况、蜱虫染蜱率、染蜱指数、体表寄生蜱的分布及蜱的季节消长规律,结果显示包头地区牛场蜱虫感染率偏低,仅有1家肉牛场有微小牛蜱感染。肉牛体表寄生此蜱主要集中在腹部鬃毛密集处,颈部肉垂处,次为两前腿和两后腿区间,占总数的85%以上。该蜱活动时间4~11月,高峰期是5月上旬、8月上旬和9月下旬。并针对蜱虫成虫活动高峰时间应采取防治措施,用1%敌百虫溶液、0.02%蜱虱敌溶液对牛体表及畜舍寄生的蜱进行喷洒杀灭,两种药物均可有效地杀灭微小牛蜱,动物健康也未见异常,可用于包头地区动物体表及圈舍蜱的杀灭药物。
