Cochineal insects are soft-bodied, flat, oval-shaped scale insects. The females, wingless and about 5 mm (0.20 in) 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 nymphs ...
Opuntia cochenillifera is a species of cactus in the subfamily Opuntioideae. It may have been endemic to Mexico, but has been widely introduced. [1] The first description was in 1753 by Carl Linnaeus as Cactus cochenillifer. Philip Miller renamed it as Opuntia cochenillifera in 1768.
A new strain of the cochineal was introduced from Opuntia stricta collected in Australia in 1997 with encouraging results. The genotype of Dactylopius opuntiae which effectively controlled Opuntia stricta in South Africa was also introduced in Kenya, resulting in the reduction in flowering and fruiting, and leading to the death of the plants.
These insects are known commonly as cochineals, [2] [3] a name that also specifically refers to the best-known species, the cochineal (Dactylopius coccus). The cochineal is an insect of economic and historical importance as a main source of the red dye carmine. It has reportedly been used for this purpose in the Americas since the 10th century. [2]
