Abstract

The article presents the results of the experience of entomological research of the Library’s book depositorys. The dependence of the state of preservation of documents on the intensity of use, storage conditions and the causes of aging are traced. Physicochemical and biological factors dangerous for the library fund are pointed out in particular inadequate lighting, the presence of dust and harmful gases, microscopic fungi, insects. Particular attention is paid to the dependence of individual resistance of paper to adverse effects on its quality. Favorable conditions for the development of biological factors that pose a threat to documents from the Library fund in terms of their material components are outlined. The reasons for the weakening of the mechanical properties of written memorabilia, the vector of the danger of loss of information content are shown. The importance of preventive and conservation measures are underlined: maintenance of normative ecological regime in book collections, observance of optimal humidity-temperature and sanitary-hygienic regimes, systematic thorough cleaning and ventilation of book depositorys, as well as control over the state of new receipts conducting periodic entomological surveys of all premises. A review of the professional literature on the protection of library collections from entomological damage are doned, standards for bioregulation, control of certain pests, restoration of entomologically damaged objects. The results of monitoring of 20 library premises according to 72 samples are presented, in which permanent residents were found: leather beetles, sinoids (book lice), ants, grinder beetles, fleas, pseudoscorpions and spiders. Hypothetical reasons for the appearance of these pests in the library and promising ways to avoid them are formulated. The system of book depository inspections, fund cleaning methods, selection of methods of pest control with the help repellents, fumigation or vacuum treatment have been developed. The article presents the results of entomological research of the Library's bookstore premises. Based on the professional literature and own findings, the vectors of biodamage prevention are outlined and the measures necessary to control insects are considered. Keywords: entomology, protection of library fund, insect pests of memos on paper and parchment.
