Some members of the genera Metatachardia, Tachardiella, Austrotacharidia, Afrotachardina, Tachardina, and Kerria are raised for commercial purposes, though the most commonly cultivated species is Kerria lacca. These insects secrete a waxy resin that is harvested and converted commercially into lac and shellac, used in various dyes, cosmetics, food glazes, wood finishing varnishes and polishes.[citation needed]
Commercially-used species include:
- Kerria lacca – true lac scale
- Paratachardina decorella – rosette lac scale
- Paratachardina pseudolobata – lobate lac scale
