Abstract:

The larvae of the Coleoptera beetle live inside the wood, digging through the wood to obtain food, which can damage the wooden components of wooden structures or ancient buildings and even cause the collapse of buildings in a short time. Therefore, damage of Coleoptera longhorned beetles highly concerned by the ancient building protection, survey, and maintenance department. Systematic research on the longhorned beetles that endanger the wooden components of antient buildings has important guiding significance for the special survey of biological diseases and the design of preventive protection schemes in the protection and investigation of wooden structures of ancient buildings. This article inquired about the reports of longhorn beetles in ancient buildings and residential houses all over the country, summarized the species, distribution, living habits, and host wood species of longhorn beetles that endangered the wooden components of ancient buildings in China, and sorted out the damage identification technology and damage classification of longhorn beetles, analyzed damage risk and preventive measures of longhorn beetles in wooden buildings or ancient buildings. The main conclusion are as follows: 1) the main species of longcorned beetles that damage the wood components of buildings in China are Trichoferus campestris, Eurypoda antinata, Stromatic longicorne and Chlorophorus didema. 2) All the wooden components of ancient buildings in China are at the damage risk from longcorned beetles. 3) The important measures to prevent the damage of longcorned beetles on buildings are wood protection before the processing of wood components, including log peeling, drying treatment, preventive treatment and other measures. 4)Ancient buildings should be regularly inspected and monitored for pests, so that pests can be found and eliminated timely.
