Native to South America. Naturalised in
southern Africa (in bushveld of Limpopo, Mpumalanga, Gauteng and
North-West). It is a
Category 1 invader plant in South Africa.
Locally referred to incorrectly as Cereus peruvianus. Two
biological control agents, a stem sucking mealiebug and a stem
boring beetle, have brought this weed completely under control in
South Africa (Klein 2011).
Ecological interactions in southern Africa
- Hypogeococcus pungens (Hemiptera: Pseudococcidae).
This is a stem sucking mealiebug that was released in South
Africa in 1983 against Harrisia martinii. It also feeds
on Cereus jamacaru, causing extensive damage (Klein
- Nealcidion cereicola (Coleoptera: Cerambycidae). This
stem boring beetle was originally released in South Africa in
1990 against Harrisia martinii but it also feeds on
Cereus jamacaru, causing considerable damage (Klein 2011).
