Schlechtendalia chinensis, the Chinese sumac aphid, is an aphid species, and the only species in the genus Schlechtendalia.[1]
The species produce galls on the Chinese sumac (Rhus chinensis). The gall is called Chinese gall, Galla Chinensis or wu bei zi (五倍子) in Chinese. It is rich in gallotannins, a type of hydrolysable tannins. The infestation by Chinese sumac aphids can lead to a gall which is valued as a commercial product. Chinese galls are used in Chinese medicine to treat coughs, diarrhea, night sweats, dysentery and to stop intestinal and uterine bleeding.[2]
