Insects are the most important class of the animal kingdom in terms of the number of species and include 2/3 of the known species. In addition to the abundance of species, they also rank first among animal groups in terms of the level of distribution and reproductive power of species.
Living in different climatic and geographical conditions is a normal and almost universal thing for insects due to their small size and very diverse adaptations. The high reproductive power and wide distribution level and the possibility of various adaptations of the morphometric, physiological and biological type have made these animals one of the resistant and invincible vital factors in nature.
Meanwhile, historical-cultural collections, given their special conditions, are no exception to this rule and require specialized studies in this field. In the initial and field studies of the library of the Niavaran Archaeological-Cultural Collection, severe insect pests were observed, so that the carpets of the collection were damaged due to the attack of insect pests. Therefore, in the first step, the pests of the collection were examined and identified, and then the damaged parts were disinfected. In this article, the various steps from diagnosis and identification to disinfection will be presented.
