The Museum of Nature and Archaeology (MUNA) in Tenerife will host a free talk on September 15, 2026, focusing on the historical and economic heritage of prickly pear cacti and cochineal in the Canary Islands, and the current crisis caused by a Mexican wild cochineal plague.

The conference, titled "The dye that created a landscape and the plague that transforms it," will take place in the auditorium of the MUNA at 7:00 PM. Admission is free until full capacity is reached.
Prickly pear cacti and traditional cochineal (Dactylopius coccus) have been a historical, cultural, and economic pillar for the Canary Islands, both for their fruit and for obtaining carmine dye. However, this heritage is now threatened by the emergence of the Mexican wild cochineal (Dactylopius opuntiae), an invasive species that devastates crops by suffocating the plant and altering the island's ecosystem.
The talk will cover the current situation of both species, their impact on the Canarian landscape, and the potential solutions being considered to mitigate the effects of the plague.
