The '''cochineal''' ({{IPAc-en|ˌ|k|ɒ|tʃ|ɪ|ˈ|n|i:|l|,_|ˈ|k|ɒ|tʃ|ɪ|n|i:|l}} {{respell|KOTCH|ih|NEEL|,_|-|neel}}, {{IPAc-en|USalso|ˌ|k|oʊ|tʃ|ɪ|ˈ|n|i:|l|,_|ˈ|k|oʊ|tʃ|ɪ|n|i:|l}} {{respell|KOH|chih|-}};<ref>{{cite LPD|3}}</ref> '''''Dactylopius coccus''''') is a [[Biology:Scale insect|scale insect]] in the suborder [[Biology:Sternorrhyncha|Sternorrhyncha]], from which the natural dye [[Chemistry:Carmine|carmine]] is derived. A primarily [[Biology:Sessility (motility)|sessile]] [[Earth:Parasitism|parasite]] native to tropical and subtropical South America through North America (Mexico and the Southwest {{wipe|United States}}), this insect lives on [[Biology:Cactus|cacti]] in the genus ''[[Biology:Opuntia|Opuntia]]'', feeding on plant moisture and nutrients. The insects are found on the pads of prickly pear cacti, collected by brushing them off the plants, and dried.

[[File:Carminic acid structure.png|thumb|250 px|Chemical structure of carminic acid, the predator-deterring substance found in high concentration in cochineal insects: The insoluble aluminium and calcium salts of this acid form red and purple dyes called "carmine".]]
The insect produces [[Chemistry:Carminic acid|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 [[Chemistry:Food coloring|colorant in food]] and in lipstick ([[Chemistry:Carmine|E120]] or [[Chemistry:Carminic acid|Natural Red 4]]).

Carmine dye was used in the Americas for coloring fabrics and became an important [[Finance:Export|export good]] in the [[History:16th century|16th century]] during the colonial period. Production of cochineal is depicted in the ''Codex Osuna'' (1565).<ref>{{cite book |title=Nahuatl Community: Cultivation of cacti for the production of the red dye cochineal.

Other species in the genus ''[[Biology:Dactylopius|Dactylopius]]'' can be used to produce "cochineal extract", and are extremely difficult to distinguish from ''D. coccus'', even for expert taxonomists; the scientific term ''D. coccus'' and the vernacular "cochineal insect" are sometimes used, intentionally or casually, and possibly with misleading effect, to refer to other species.{{NoteTag|The primary biological distinctions between species are minor differences in host plant preferences, along with very different geographic distributions.}}

==Etymology==
The word cochineal is derived from the French "''cochenille''", derived from Spanish "''cochinilla''", in turn derived from Latin "''coccinus''" meaning "scarlet-colored", or from the Latin "''coccum''", meaning "berry yielding scarlet dye". A related word [[Biology:Kermes (insect)|''kermes'']] refers to the source of a weaker red Mediterranean dye also called [[Crimson|crimson]], which was used in Europe to color cloth red before cochineal was imported from the New World to Spain in the 1520s. Some sources identify the Spanish source word for cochineal as ''cochinilla'' "wood louse" (a diminutive form of Spanish ''cochino'', cognate with French ''cochon'', meaning "pig").<ref>{{cite web |url=http://www.etymonline.com/index.php?term=cochineal&allowed_in_frame=0 |title=Cochineal |publisher=Online Etymology Dictionary |access-date=2015-05-06 |archive-date=2015-06-01 |archive-url=https://web.archive.org/web/20150601200901/http://www.etymonline.com/index.php?term=cochineal&allowed_in_frame=0 |url-status=live }}</ref>

==Dactylopius coccus==
===Life cycle===
[[File:Dactylopius coccus (Barlovento) 04 ies.jpg|thumb|A cluster of females]]
Cochineal insects are soft-bodied, flat, oval-shaped scale insects. The females, wingless and about {{convert|5|mm|abbr=on}} long, cluster on cactus pads. They penetrate the cactus with their beak-like mouthparts and feed on its juices, remaining immobile unless alarmed. After mating, the fertilised female increases in size and gives birth to tiny [[Biology:Nymph|nymph]]s. The nymphs secrete a [[Physics:Wax|wax]]y [[White|white]] substance over their bodies for protection from water loss and excessive sun. This substance makes the cochineal insect appear white or grey from the outside, though the body of the insect and its nymphs produces the red pigment, which makes the insides of the insect look dark purple. Adult males can be distinguished from females in that males have wings, and are much smaller.<ref name="Eisner">{{Cite book | last=Eisner | first=T. |  title=For Love of Insects | year=2003 | publisher=Belknap Press of Harvard University Press | location=Cambridge, Massachusetts | isbn=0-674-01827-3 | url-access=registration | url=https://archive.org/details/isbn_9780674018273 }}</ref>

[[File:Cochineal on opuntia.jpg|thumb|Cochineal on opuntia in California]]
The cochineal disperses in the first nymph stage, called the "crawler" stage. The juveniles move to a feeding spot and produce long wax filaments. Later, they move to the edge of the cactus pad, where the wind catches the wax filaments and carries the insects to a new host. These individuals establish feeding sites on the new host and produce a new generation of cochineals.<ref name="urb">{{cite web | last=Olson |first=C. | title= Cochineal | work= Urban Integrated Pest Management | url= http://ag.arizona.edu/urbanipm/insects/cochineal.html | archive-url= https://web.archive.org/web/20051119071257/http://ag.arizona.edu/urbanipm/insects/cochineal.html | archive-date= November 19, 2005 | access-date=July 19, 2005 }}</ref> Male nymphs feed on the cactus until they reach sexual maturity.

===Host cacti===
[[File:Cochenille z01.jpg|thumb|right|Cochineals on cacti in [[Earth:La Palma|La Palma]], Canary Islands]]
''Dactylopius coccus'' is native to tropical and subtropical South America and North America in Mexico, where their host cacti grow natively. They have been widely introduced to many regions where their host cacti also grow. About 200 species of ''Opuntia'' cacti are known, and while it is possible to cultivate cochineal on almost all of them, the most common is ''[[Biology:Opuntia ficus-indica|Opuntia ficus-indica]]''.<ref name="oxa">{{cite web | title=Cultivation of Cochineal in Oaxaca | work=Go-Oaxaca Newsletter | url=http://www.go-oaxaca.com/newsletter/cochineal.html | access-date=July 15, 2005 |archive-url=https://web.archive.org/web/20080608102822/http://www.go-oaxaca.com/newsletter/cochineal.html |archive-date=June 8, 2008}}</ref> ''D. coccus'' has only been noted on ''Opuntia'' species, including ''O. amyclaea'', ''O. atropes'', ''O. cantabrigiensis'', ''O. brasilienis'', ''O. ficus-indica'', ''O. fuliginosa'', ''O. jaliscana'', ''O. leucotricha'', ''O. lindheimeri'', ''O. microdasys'', ''O. megacantha'', ''O. pilifera'', ''O. robusta'', ''O. sarca'', ''O. schikendantzii'', ''O. stricta'', ''O. streptacantha'', and ''O. tomentosa''.<ref name="mex" /> Feeding cochineals can damage and kill the plant. Other cochineal species feed on many of the same ''Opuntia'', and the wide range of hosts reported for ''D. coccus'' likely is because of the difficulty in distinguishing it from other ''Dactylopius'' species.<ref>{{cite book |title=Atlas of the Scale Insects of North America, Volume VII |last=Ferris |first=G. Floyd |year= 1955|publisher= Stanford University Press|isbn=0-8047-1667-6 |pages=85–90 }}</ref>

===Predation===
Several natural enemies can reduce the population of the insects on hosts. Of all the predators, insects seem to be the most important group. Insects and their larvae such as [[Biology:Pyralidae|pyralid moth]]s (order [[Biology:Lepidoptera|Lepidoptera]]), which destroy the cactus, and predators such as lady bugs ([[Biology:Coleoptera|Coleoptera]]), various [[Biology:Diptera|Diptera]] (such as [[Biology:Syrphidae|Syrphidae]] and [[Biology:Chamaemyiidae|Chamaemyiidae]]), lacewings ([[Biology:Neuroptera|Neuroptera]]), and ants ([[Biology:Hymenoptera|Hymenoptera]]) have been identified, as well as numerous parasitic wasps. Many birds, human-[[Biology:Commensalism|commensal]], rodents (especially rats), and reptiles, also prey on cochineal insects.<ref name="mex" />

===Farming===
A [[Biology:Nopal|nopal]] cactus farm for the production of cochineal is traditionally known as a ''nopalry''.<ref>{{cite web |url=http://www.webster-dictionary.net/definition/Nopalry |title=definition of ''nopalry'' from Webster Dictionary. Accessed Nov. 4, 2009 |publisher=Webster-dictionary.net |access-date=November 13, 2009 |archive-date=July 16, 2011 |archive-url=https://web.archive.org/web/20110716144733/http://www.webster-dictionary.net/definition/Nopalry |url-status=live }}</ref> The two methods of farming cochineal are traditional and controlled. Cochineals are farmed in the traditional method by planting infected cactus pads or infesting existing cacti with cochineals and harvesting the insects by hand. The controlled method uses small baskets called Zapotec nests placed on host cacti. The baskets contain clean, fertile females that leave the nests and settle on the cactus to await fertilization by the males. In both cases, the cochineals must be protected from [[Earth:Predation|predation]], cold, and rain. The complete cycle lasts three months, during which time the cacti are kept at a constant temperature of 27&nbsp;°C (81&nbsp;°F). At the end of the cycle, the new cochineals are left to reproduce or are collected and dried for dye production.<ref name="oxa" />

[[Image:Cochinel Zapotec nests.jpg|right|thumb|Zapotec nests on ''O. ficus-indica'']]
To produce dye from cochineals, the insects are collected when they are around 90 days old. Harvesting the insects is labour-intensive, as they must be individually knocked, brushed, or picked from the cacti and placed into bags. The insects are gathered by small groups of collectors who sell them to local processors or exporters.<ref name="foo">{{cite web | author=Foodnet | title=Tropical commodities and their markets | url=http://www.foodnet.cgiar.org/market/Tropcomm/part2c2.htm | access-date=July 14, 2005  | archive-url=https://archive.today/20120731165220/http://www.foodnet.cgiar.org/market/Tropcomm/part2c2.htm | archive-date=July 31, 2012 }}</ref>

In regions dependent on cochineal production, pest control measures are taken seriously. For small-scale cultivation, manual methods of control have proved to be the safest and most effective. For large-scale cultivation, advanced pest control methods have to be developed, including alternative bioinsecticides or traps with [[Biology:Pheromone|pheromone]]s.<ref name="mex" />

====Failed farming in Australia====
''Opuntia'' species, known commonly as prickly pears, were first brought to {{wipe|Australia}} in an attempt to start a cochineal dye industry in 1788. Captain Arthur Phillip collected a number of cochineal-infested plants from Brazil on his way to establish the first European settlement at Botany Bay, part of which is now [[Place:Sydney|Sydney]], New South Wales. At that time, Spain and Portugal had a worldwide cochineal dye monopoly via their New World colonial sources, and the British desired a source under their own control, as the dye was important to their clothing and garment industries; it was used to color the British soldiers' red coats, for example.<ref>{{cite web |url=http://www.northwestweeds.nsw.gov.au/prickly_pear_history.htm |title=Prickly Pear in Australia |publisher=Northwestweeds.nsw.gov.au |date=June 26, 1987 |access-date=November 13, 2009  |archive-url=https://web.archive.org/web/20091030181043/http://www.northwestweeds.nsw.gov.au/prickly_pear_history.htm |archive-date=October 30, 2009 }}</ref> The attempt was a failure in two ways: the Brazilian cochineal insects soon died off, but the cactus thrived, eventually overrunning about {{convert|100000|sqmi|km2|sigfig=3|abbr=on}} of eastern Australia.<ref name="Greenfieldp188">{{Harvnb|Greenfield|2005|p=188}}.</ref> The cacti were eventually brought under control in the 1920s by the deliberate introduction of a South American moth, ''[[Biology:Cactoblastis cactorum|Cactoblastis cactorum]]'', the larvae of which feed on the cactus.<ref name="Greenfieldp188" />

====Failed farming in Ethiopia====
The nopal pear has been traditionally eaten in parts of northern Ethiopia, where it is utilized more than cultivated. Carmine cochineal was introduced into northern Ethiopia early in the 2000s to be cultivated among farming communities. Foodsafe exported 2000 tons of dried carmine cochineal over 3 years.{{Citation needed|date=January 2021}}

A conflict of interest among communities led to closure of the cochineal business in Ethiopia, but the insect spread and became a pest. Cochineal infestation continued to expand after the cochineal business had ended. Control measures were unsuccessful and by 2014 about {{convert|16000|ha|mi2}} of cactus land had become infested with cochineal.<ref>Tesfay Belay Reda. 2014.

====Biocontrol in South Africa====

There has been a population of ''Dactylopius'' insects on prickly pear cactuses around Cuyler Manor in Uitenhage; several cochineal species were introduced to South Africa{{When|date=September 2023|reason=source leaflet doesn't say}}, with use encouraged as a biocontrol for different invasive cactus plant species.<ref>{{Cite report|date=2002 |title=Cochineal insects (Dactylopius species)|last=Klein|first=Hildegard|url=https://www.arc.agric.za/arc-ppri/Fact%20Sheets%20Library/Cochineal%20insects%20Dactylopius%20spp.pdf |publisher=Agricultural Research Council (South Africa) - PPRI Leaflet Series: Weeds Biocontrol, No. 2.2 }} ISBN 1-86849-168-4<!--ISBN listed in leaflet, but doesn't work, not useful as template parameter-->}}</ref>

Cochineal dyes are one of three groups of red insect dyes, all of which are anthraquinone derivatives. The major color components in their respective chemical structures are [[Chemistry:Carminic acid|carminic acid]] (in cochineal dyes), kermesic acid (in [[Biology:Kermes (dye)|kermes dye]]) and laccaic acids (in [[Biology:Lac (resin)|lac]] dye).<ref name="Cooksey">{{cite journal |last1=Cooksey |first1=C.

The dye bonds best with animal fibers rather than plant fibers and was most effective for dying wool from alpacas and other ''[[Biology:Camelidae|Camelidae]]'', rabbit fur, and feathers. It was also used on cottons and plant-based fabrics, to less effect.  Some examples of early cloth have survived in extremely dry areas in Peru.  In addition, the use of cochineal is literally illustrated in drawings on codices and maps. Production of cochineal dyes became well-developed under Nazca culture, and beautiful examples of woven cloth colored by cochineal remain from Moche and Wari culture.<ref name="Phipps"/>{{rp|12–25}}<ref name="Orna">{{cite journal |last1=Orna |first1=Mary Virginia |title=Chemistry and Art: Ancient textiles and medieval manuscripts examined through chemistry |journal=Educación Química |date=1 July 2011 |volume=22 |issue=3 |pages=191–197 |doi=10.1016/S0187-893X(18)30133-2 |language=es |issn=0187-893X |doi-access=free }}</ref>

====Use as pigment====
Prior to the Spanish invasion, Aztecs also used cochineal pigments in their manuscripts.  The 16th century ''Florentine Codex'' contains a variety of illustrations with multiple variations of the red pigments. Specifically in the case of ''achiotl (light red)'', technical analysis of the paint reveals multiple layers of the pigment although the layers of the pigment is not visible to the naked eye. Therefore, it proves that the process of applying multiple layers is more significant in comparison to the actual color itself. Furthermore, the process of layering the various hues of the same pigment on top of each other enabled the Aztec artists to create variations in the intensity of the subject matter. A bolder application of pigment draws the viewer's eye to the subject matter which commands attention and suggests a power of the viewer. A weaker application of pigment commands less attention and has less power.

====Comparable colors====
In Europe, there was no comparable red dye or pigment. The closest color was ''[[Biology:Kermes (dye)|Kermes]]'' (technically, [[Crimson|crimson]]), one of the oldest organic pigments. Its key ingredient, kermesic acid, was also extracted from an insect, ''[[Biology:Kermes vermilio|Kermes vermilio]]'', which lives on ''[[Biology:Quercus coccifera|Quercus coccifera]]'' oaks native to the Near East, and the European side of the Mediterranean Basin. Kermes was used as a dye and a laked pigment in ancient Egypt, Greece, Armenia and the Near East.<ref>Barber, E. J. W. (1991). ''Prehistoric Textiles''.

====Colonial export====
The Spanish conquest of the Aztec Empire in the 16th century introduced new colors to peoples on both sides of the Atlantic. The Spanish were quick to exploit the vibrant, intense color of cochineal for new trade opportunities. [[Chemistry:Carmine|Carmine]] attained great status and value in Europe.<ref name=":0" /><ref name = Eiland55/>

During the colonial period, with the introduction of sheep to Latin America, the use of cochineal increased. It provided the most intense color and it set more firmly on woolen garments compared to clothes made of materials of pre-Hispanic origin such as [[Biology:Cotton|cotton]] or [[Biology:Agave|agave]] and [[Biology:Yucca|yucca]] fibers. In general, cochineal is more successful on protein-based animal fibres (including silk) than plant-based material.<ref name = Eiland55/>

During the colonial period in Latin America, many indigenous communities produced cochineal under a type of contract known as Repartimiento de Mercancías. This was a type of "contract forwarding" agreement, in which a trader lent money to producers in advance, with a "[[Finance:Call option|call option]]" to buy the product once it was harvested.  Communities with a history of cochineal production and export have been found to have lower poverty rates and higher female literacy, but also smaller indigenous populations.<ref>{{cite journal |author1=Diaz-Cayeros, Alberto |author2=Jha, Saumitra |year=2012 |title=Contracts and Poverty Alleviation in Indigenous Communities: Cochineal in Mexico |journal=Global Trade |url=http://eh.net/eha/wp-content/uploads/2013/11/Diazetal.pdf |access-date=2015-01-30 |archive-date=2015-01-30 |archive-url=https://web.archive.org/web/20150130222123/http://eh.net/eha/wp-content/uploads/2013/11/Diazetal.pdf |url-status=live }}</ref>

==== Production elsewhere ====
In 1777, French botanist Nicolas-Joseph Thiéry de Menonville, presenting himself as a botanizing physician, smuggled the insects and pads of the ''Opuntia'' cactus to Saint Domingue. This particular collection failed to thrive and ultimately died out, leaving the Mexican monopoly intact.{{sfn|Schiebinger|2004|p=44}} 
After the Mexican War of Independence in 1810–1821, the Mexican monopoly on cochineal came to an end. Large-scale production of cochineal emerged, especially in Guatemala and the Canary Islands; it was also cultivated in Spain and North Africa.<ref name = Eiland55/>

====Competition from artificial dyes====
The demand for cochineal fell sharply in the middle of the 19th century, with the appearance of artificial dyes such as [[Chemistry:Alizarin|alizarin crimson]]. This caused a significant financial shock in Spain as a major industry almost ceased to exist.<ref name="behan"/> The delicate manual labour required for the breeding of the insect could not compete with the modern methods of the new industry, and even less so with the lowering of production costs. The "''tuna'' blood" dye (from the Mexican name for the ''Opuntia'' fruit) stopped being used and trade in cochineal almost totally disappeared in the course of the 20th century. For a time, the breeding of cochineal was done mainly for the purposes of maintaining the tradition rather than to satisfy any sort of demand.<ref name="coc">{{cite web|last=Hernández |first=O. |title=Cochineal |work=Mexico Desconocido Online |url=http://www.mexicodesconocido.com.mx/notas/7600-Cochineal |access-date=July 15, 2005  |archive-url=https://web.archive.org/web/20071016060906/http://www.mexicodesconocido.com.mx/notas/7600-Cochineal |archive-date=October 16, 2007 }}</ref>
