A survey was conducted in some historic buildings in Nikko in 2009 using adhesive traps to clarify insect species that cause damage on historic buildings. Some characteristic species of Anobiidae were found as timber pests. Priobium cylingricum was trapped at Sambutsu-do of Rinnohji temple while Trichodesma japonicum and Sculptotheca hilleri were trapped at Daiyu-in Nitenmon. Large-scale survey in historic buildings in Nikko was conducted in 2010. About 27,000 adhesive traps were used for surveys in the loft and basement space of 72 historic wooden buildings. As a result,reality of living conditions of the Anobiids that can harm the buildings in the whole area was revealed. Hadrobregmus pertinax and Oligomerus japonicus, which were not found in the previous year, were also found in 2010. It is assumed that Anobiidae inhabit the entire Nikko area. The distribution of pests in some major buildings have been scrutinized by previous large-scale survey data. As a result, some correspondences have been found with the results of visual survey of damage to building materials. Interesting ecological characteristics of wood-boring beetles were shown from the data, including light attraction. Those data can be useful for future treatments such as fumigation,as well as for restoration and conservation. |
