According to Mireya Manfrini and Claudio Sosa, Center of Entomological Research, National University of Cordoba, in Argentina, can talk about three groups, specifically according to their possible danger for archives and libraries. In the first group would be subterranean termites, which create their nests on the ground and underground penetrate into the building, damaging timber and paper. Termites that require an environment with high humidity, but adapt well to libraries because the paper offers less resistance which the wood is located in the second group. Finally, dry wood termites are found whose most dangerous representative, the Cryptotermes brevis, lives in beams, furniture, wood floors, etc. and destroys almost the entire interior of the piece that holds them.
Apart from cellulose, they eat leather and parchment, and although they cannot live in a very dry environment, endure well air conditioning. But termites aren’t the only danger. Cockroaches also make much damage and are common in libraries and archives black cockroach, the blonde and American or cucarachon, that you can reach 5 inches in size. The damage they produce books can be very serious, especially in tropical regions, where the paper attracts them by its humidity. In addition, eaten carton, scraping labels on the reverse sides of the books, attacking its binding and soiled paper with their droppings.Also other insects so common as ants, wasps, bees, bumblebees, etc do not directly harm the paper, but indirectly harm it build their nests or put their eggs in it. Butterflies and moths, are its larvae or caterpillars which can attack works, since they possess Masticator oral appliance. A species of cricket, Gryllus the damesticus, also consumes paper, as well as fabric, leather and adhesives and, sometimes, is voracious. Their damage is similar to that produced by cockroaches. Known as books, Trogium lice pulsatorium and Liposcelis divinatorius, tend to be discovered too late, since the damage they produce is not generalized quickly.
