Females and nymphs secrete and cover themselves with white waxy filamentous secretions.
The red crawlers are armed with long filaments on the posterior part of their abdomen. Reproduction of this species is usually sexual, the sex ratio female: Each female excretes an ovisacinto which it lays an average dactyllopius eggs. Some crawlers settle nearby, but most move to the highest point of the cladode to be wind-dispersed, their wax threads providing buoyancy.
The females attach themselves to the plants and remain there for the rest of their lives.
The short-lived males pupate to opuntias winged adults. The feeding of the scale induces yellow areas on the cladode within a few weeks, subsequently causing its drop. The pest is capable of killing small cacti within months, or a large cactus within two years.
It is a major pest of cactus plantations in South America, and has recently invaded Israel. On the other hand, D.

Attacked cacti that are still alive after two years should be removed, and the cochineal-infested cladodes destroyed. Some species of Opuntiaor clones thereof, are fully or partially resistant to the scale.
Several organic compounds have been applied against the pest, including neutral detergent concentrations, cassava starch, liquid wastes, terpenoids, mineral oils and neemwhich was the most efficient.
A pyrethroid and an organophosphate also provide control of the cochineal. Predators of the families ChamaemyiidaeCoccinellidae and Hemerobiidae attack the pest in Mexico.
