Cochineal

Cochineal \Coch"i*neal\ (k[o^]ch"[i^]*n[=e]l; 277), [Sp. cochinilla, dim. from L. coccineus, coccinus, scarlet, fr. coccum the kermes berry, G. ko`kkos berry, especially the kermes insect, used to dye scarlet, as the cochineal was formerly supposed to be the grain or seed of a plant, and this word was formerly defined to be the grain of the Quercus coccifera; but cf. also Sp. cochinilla wood louse, dim. of cochina sow, akin to F. cochon pig.] A dyestuff consisting of the dried bodies of females of the Coccus cacti, an insect native in Mexico, Central America, etc., and found on several species of cactus, esp. Opuntia cochinellifera.

Note: These insects are gathered from the plant, killed by the application of heat, and exposed to the sun to dry. When dried they resemble small, rough berries or seeds, of a brown or purple color, and form the cochineal of the shops, which is used for making carmine, and also as a red dye.

Note: Cochineal contains as its essential coloring matter carminic acid, a purple red amorphous substance which yields carmine red.

Douglas Harper's Etymology Dictionary
cochineal

1580s, from French cochenille (16c.), probably from Spanish cochinilla, from a diminutive of Latin coccinus (adj.) "scarlet-colored," from coccum "berry (actually an insect) yielding scarlet dye" (see kermes). But some sources identify the Spanish source word as cochinilla "wood louse" (a diminutive form related to French cochon "pig").\n

\nThe insect (Coccus Cacti) lives on the prickly pear cactus in Mexico and Central America and is a relative of the kermes and has similar, but more intense, dying qualities. Aztecs and other Mexican Indians used it as a dyestuff. It first is mentioned in Europe in 1523 in Spanish correspondence to Hernán Cortés in Mexico. Specimens were brought to Spain in the 1520s, and cloth merchants in Antwerp were buying cochineal in insect and powdered form in Spain by the 1540s. It soon superseded the use of kermes as a tinetorial substance. Other species of coccus are useless for dye and considered mere pests, such as the common mealy bug.

Wikipedia
Cochineal

The cochineal ( or ; Dactylopius coccus) is a scale insect in the suborder Sternorrhyncha, from which the natural dye carmine is derived. A primarily sessile parasite native to tropical and subtropical South America as well as Mexico and Arizona, this insect lives on cacti in the genus Opuntia, feeding on plant moisture and nutrients. These insects are found on the pads of prickly pear cacti, then are brushed off and dried.

The insect produces carminic acid that deters predation by other insects. Carminic acid, typically 17-24% of dried insects' weight, can be extracted from the body and eggs, then mixed with aluminium or calcium salts to make carmine dye, also known as cochineal. Today, carmine is primarily used as a colorant in food and in lipstick.

The carmine dye was used in Central America in the 15th century for coloring fabrics and became an important export good during the colonial period. After synthetic pigments and dyes such as alizarin were invented in the late 19th century, natural-dye production gradually diminished. Health fears over artificial food additives, however, have renewed the popularity of cochineal dyes, and the increased demand has made cultivation of the insect profitable again, with Peru being the largest exporter. Some towns in the Mexican state of Oaxaca are still working in handmade textiles using this cochineal.

Other species in the genus Dactylopius can be used to produce cochineal extract, but they are extremely difficult to distinguish from D. coccus, even for expert taxonomists, and the latter scientific name (and the vernacular "cochineal insect") is therefore commonly used when one is actually referring to other biological species. The primary biological distinctions between species are minor differences in host plant preferences, in addition to very different geographic distributions.
