Asian Longhorned Tick, an Invasive Tick in the United States

Abstract

The Asian longhorned tick, Haemaphysalis longicornis, is also known as the cattle tick or bush tick. It is native to East Asia: China, Korea, Japan, and well established in Australia and New Zealand. It is also an invasive tick species in the United States (U.S.). This tick is a serious pest of livestock and wildlife in several countries (Heath 2016, Guan et al. 2010). If the Asian longhorned tick becomes established in Arizona, it could become a serious threat to livestock, wildlife, and pets.
