Abstract

Una de las causas principales de pérdida de patrimonio histórico en los museos es el ataque de insectos. En el Museo del Convento de los Descalzos (Lima, Perú) este problema es muy agudo, especialmente en sus libros corales, que datan de los siglos XVII a XIX, debido a los materiales utilizados en su fabricación. Algunos tratamientos para desinsectar objetos requieren compuestos que pueden dañarlos o que son tóxicos. Una alternativa no agresiva y efectiva para la desinsectación es el tratamiento anóxico. En este caso, los libros fueron introducidos en bolsas de aluminio plastificado llenas de nitrógeno y con un inhibidor de oxígeno. La efi-cacia del tratamiento fue confirmada con placas radiográficas de los libros. Este método de desinsectación, poco costoso y fácilmente adaptable, fue exitoso y constituye una buena manera de detener el deterioro por infestación de xilófagos, tanto de los libros corales como de otros objetos de valor artístico e histórico. __________ One of the main causes of loss of historical heritage in museums is an insect attacks. At the Museo del Convento de los Descalzos in Lima, Peru, this is a severe problem, particularly in its choral books, which date from the 17th to 19th centuries, due to the materials used in their manufacture. Some disinfestation treatments for objects require compounds that either damage them or are toxic. A non-aggressive and effective alternative to disinfestation is anoxic treatment. In this case, the books were placed in laminated aluminum bags filled with nitrogen and an oxygen inhibitor. The treatment's efficiency was confirmed through X-ray images of the books. This inexpensive and easily adaptable disinfestation method was successful and constitutes a noteworthy way to stop the deterioration caused by xylophagous infestation, both of choral books and other objects of artistic and historical value.
