Distribution, systematics and endangerment
Opuntia cochenillifera is believed to have originally come from Mexico , but is now common in warmer areas around the world.
The first description according to the rules of binary nomenclature was in Species Plantarum as Cactus cochenillifer by Carl von Linné . Philip Miller assigned it in 1768 to the genus Opuntia established by him . For a long time, numerous authors considered Joseph zu Salm-Reifferscheidt-Dyck 's classification in the now no longer recognized genus Nopalea necessary (as Nopalea cochenillifera ).
In the Red List of Threatened Species of the IUCN , the species is called " Data Deficient (DD) ", i. H. with insufficient data. The future development of the populations is unknown.
use
Opuntia cochenillifera is one of the most important host plants for the female cochineal scale insects (especially Dactylopius coccus ), from which the pigment carmine is made. 140,000 insects are necessary to produce 1 kilogram of carmine powder.
In Mexico and Central America , Opuntia cochenillifera is used as an antifungal agent. Furniture was made from their wood .
