Abstract

The numbers of bush ticks, Haemaphysalis longicornis, on Bos taurus steers in south east Queensland was recorded regularly from July 1971 until January 1974. The steers had no prior exposure to the tick. The parasitic tick population was large during the first year, but declined to low levels in the second and third years, apparently as a result of the steers acquiring resistance to tick feeding.

摘要

1971年7月至1974年1月期间,昆士兰州东南部定期记录了饲养在那里的肉牛(Bos taurus)身上长角血蜱(Haemaphysalis longicornis)的数量。这些肉牛此前未接触过这种蜱虫。寄生蜱虫数量在第一年很多,但在第二年和第三年降至低水平,这显然是因为肉牛对蜱虫叮咬产生了抗性。
