Research into the biological control of pereskia has been carried out intermittently since the 1980s. A leaf-feeding flea beetle species, Phenrica guerini, was released during 1991 and became established in various coastal sites in KwaZulu-Natal and the Eastern Cape provinces. Although it can cause considerable damage to leaves locally, it has not exerted any significant degree of control on a large scale.
