The article “Principles for the technical curatorship of the entomological collection of the Museum of Zoology of the University of São Paulo”, prepared by the team from the Museum's Laboratory of Systematics, Evolution and Biology of Hymenoptera, lists issues of major relevance for absolutely current and central discussions about the importance - not always recognized - of all types of collections, including entomological ones. As the authors conclude, “the collections represent accumulated knowledge about past and present biodiversity, providing valuable information for policy decisions and scenario projections, in addition to constituting an inexhaustible source of essential information”2 for future challenges.
