Aceria (genus - on weeds)

This is a large genus of gall mites which contains around 1000 species. The mites feed on the surface of leaves, inflorescences and fruits. The feeding activity induces the formation of tumour-like galls or scarring of the fruit surface. Several are economical pests, however, other species are beneficial biological control agents which infest specific weeds.

For species harmful to crops see Aceria (plant pests).

• Aceria anthocoptes (on weeds)
• Aceria genistae (on weeds)
• Aceria lantanae (on weeds)

• Aceria malherbae (on weeds)
• Aceria solstitialis (on weeds)
