Memoria sobre a cultura da Urumbeba e sobre criação da Cochonilha

A 1777 expedition set out from the coast of Brazil to study a hardy cactus the locals call Urumbeba, known in Mexico as Nopal. The observer records how the plant thrives on sandy soil and can be cultivated along the beaches north of Rio de Janeiro, offering a new source of food, timber and, most importantly, a home for a tiny but valuable insect. The narrative blends practical farming advice with vivid descriptions of the landscape, showing how the cactus could transform marginal lands into productive farms.

The report then turns to the cochineal insect that lives on the cactus, long prized in Europe and Asia for its brilliant red pigment. By detailing the methods needed to raise and protect the bugs, the author argues that Brazil could break a monopoly once held by Mexico and create a lucrative export. The early observations promise a fresh avenue for colonial commerce while illustrating the challenges of transplanting a foreign ecosystem to a new continent.
