Abstract
Abstract A rust mite not previously reported in the U.S. was observed on Canada thistle (Cirsium arvense [L.] Scop.) growing in Maryland. Based on examination of specimens under light and low-temperature scanning electron microscopy, the mite was identified as the rust mite, Aceria anthocoptes (Nalepa). The mite was found throughout Maryland, in its bordering states, and in two northcentral states (Minnesota and North Dakota). Other Cirsium species growing near Canada thistle infested with A. anthocoptes did not harbor the mite. We conclude that, although only recently discovered in this geographic region, A. anthocoptes is widely distributed in the mid-eastern U.S. and is host specific to Canada thistle.
