Rhipicephalus microplus）为硬蜱科扇头蜱属下的一个种，在经济上地位重要，因为牠会寄生在多个家畜的物种的身上，例如：牛只、水牛、马、驴、山羊、鹿、 猪及部份野生动物。本物种主要在亚洲生活，但亦有见于澳大利亚部份地区、马达加斯加、 加勒比海及中、南美洲（包括墨西哥）。本物种过往亦曾出现于美国，但自从美墨边境严格运行检查之后，在美国的出现机率大幅陆低。1917年，时任美国路易斯安那州州长的Ruffin Pleasant签署法令，以铲走在当地牛只生长的本物种

Rhipicephalus microplus (formerly Boophilus microplus) is an economically important tick that parasitises a variety of livestock species; it is known as the cattle tick or southern cattle tick. It has been recorded on "cattle, buffalo, horses, donkeys, goats, sheep, deer, pigs, dogs and some wild animals". It is found in Asia, parts of Australia, on Madagascar, in southeastern Africa, in the Caribbean, South and Central America and Mexico. Having formerly been present in the United States, it has since been eradicated there, except for sporadic occurrences in a buffer zone along the Mexican border.
