Schwiebea is a genus of mites in the family Acaridae. It is among the largest in the family with over 60 species.

Description

Adults of Schwiebea are distinguished from other mites by: the absence of many setae, the reduction of supracoxal seta of leg I to a tiny spine, and the absence of Grandjean's organ. Additionally, the propodosomal sclerite has a posterior indentation/incision for up to 50% of its length. Females have a spermatheca (organ for receiving and storing sperm) and its morphology is important for distinguishing species.

Habitat

Schwiebea have been collected from various habitats including vegetation (clover roots, a verbena field, peony rose, Gerbera roots, yams, taro seeds), leaf litter, peat moss, caves, insect rearing containers and even some aquatic environments (fish farms, aquariums, swimming pools). Some species attach phoretically to arthropods such as bark beetles, millipedes and ticks.

Reproduction

Some species of Schwiebea are all-female and reproduce by parthenogenesis, while others use sexual reproduction. Parthenogenesis is thought to have evolved at least three times within the genus.

Pest status

One species, S. similis, is a pest of American ginseng in China. A scientific study found it can also feed on other crops to varying extents, including garlic, potato and Chinese yam.
