Abstract: Objective Objective To investigate the Histiostomas apromyzarum breeding in traditional Chinese medicine Rhizoma Bletillae. Methods Methods The scurf and dust of R. bletillae were obtained by brushing，and the mites samples were separated and identified. Results Results Totally 520 g samples were collected，and 56 adult mites（female?male ratio 0.12）and 18 dormant bodies were obtained from the samples，and they were identified as H. apromyzarum with an average breeding density of 0.14/g. Con Con? ? clusion clusion H. apromyzarum could breed on the traditional Chinese medicine R. bletillae，and the corresponding control mea? sures should be strengthened.
