Quite a few mites in a number of taxonomic genera feed on bamboo.
In a single examine, 45 species from 23 genera and 9 taxonomic households had been collected from moso rising in Fujian, China. Widespread moso, or tortoiseshell bamboo, Phyllostachys edulis, grows outside in USDA Hardiness Zones 7 to 10.
The mites that do essentially the most injury to bamboo are within the following households:
Stigmeopsis (syn. Schizotetranychus) is a spider mite genus within the Tetranychidae household talked about above.
