Insect infestations seriously threaten the safety of organic cultural relics and ancient buildings. Every year, the Palace Museum spends a large amount of money and time on the prevention and control of cultural relics pests, but there is still no systematic and targeted method. The Hall of Mental Cultivation is a representative and important building in the Forbidden City. Through three years of pest investigation, the species, occurrence mechanism and development trend of the main pests were discovered. During the investigation, more than 10 species of insects were trapped. Pests of cultural relics included carpet beetle (Anthrenus picturatus hintoni Mroczkowski and Thylodrias contractus Motschulsky), silverfish (Ctenolepisma villosa), powder post beetle (Lyctus brunneus Stephens), booklice (Loposcelis bostrychophila), spider beetle (Ptinus japonicus Reitter and Gibbium aequinoctiale Boieldieu) and clothes moth (Tinea pellionella), among which the Anthrenus picturatus hintoni Mroczkowski was the primary pests. Abundant resources of organic cultural relics, suitable temperature, humidity and light environment, and the existence of cypress are favorable factor for the occurrence of pests. Analysis of these triggers is helpful for Integrated Pest Management. The period with the largest number of active pests in the Hall of Mental Cultivation is July and August. April, May are the rapid growth period, and the influence of the carpet beetles on the overall change trend is significant. Combined with the living habits of main insect pest——carpet beetles, the killing time of different killing means can be effectively grasped: fumigation should be in July and August when the maximum amount, while chemical spray should be combined with the flowering period of trees (March to May).
