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.
These insects are known commonly as cochineals, [2] [3] a name that also specifically refers to the best-known species, the cochineal (Dactylopius coccus).

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.
