Memoria sobre a cultura da Urumbeba e sobre criação da Cochonilha
"Memoria sobre a cultura da Urumbeba e sobre criação da Cochonilha" by M. Thiery de Menonville is a scientific publication written in the late 18th century. The book discusses the cultivation of the Urumbeba plant, a type of cactus significant in the production of Cochonilha, an insect whose dye extract was valuable for trade. It highlights agricultural techniques and observations aimed at improving the economic output of this natural resource in the colonies. The text details the journey and research conducted by Menonville in Mexico, where he studied the Cochonilha and its habitat, the Urumbeba. He describes the challenges faced in transporting the delicate insects and plants, as well as the nuances of their care and cultivation. Furthermore, the book compares different species of Cochonilha and their respective qualities, emphasizing the economic potential of establishing Urumbebals (plantations of Urumbeba) in regions with sandy soil unsuitable for other crops. Menonville's meticulous observations aim to revive and enhance local agricultural practices to leverage the lucrative market for Cochonilha dye, asserting its importance for commerce in Europe and beyond.
