 note = {A very rare anobiid species in Japan, Priobium cylindricum, was found by chance in the restoration work of the Sambutsu-do of Rinnohji temple in 2008. Severe damage was found in some structural wooden pieces of the temple. The damage was very severe in hard (heart) wood: a powdery state and many holes of various sizes were seen. However, damage was not clear when seen from the red painted layer of urushi. At another structure, Daiyu-in Nitenmon, anobiids, Trichodesma japonicum and Sculptotheca hilleri, were trapped by adhesive ribbons in 2009. Since adhesive ribbons turned to be effective tools in investigating signs of infestation, extensive survey of insects with adhesive traps (about 27,000 ribbons) in about seventy historic buildings in the Nikko World Heritage site was performed from the end of April to August, 2010. Several species of anobiid were found on the adhesive traps. Some of them had caused infestation at certain buildings.
 At the Sambutsu-do of Rinnohji temple, extensive restoration is now planned for the next ten years. In the process, it is very important to completely eradicate all anobiid insects inside the wooden pieces which would be reused in the restoration. For the purpose, experiments on CO2 treatment and sulfuryl fluoride (Vikane®) fumigation were performed.
 Firstly, tests were performed on actual wooden blocks from the structure damaged by Priobium cylindricum. Effects of the treatments were examined by X-ray CT (computer tomography) scanning, and comparing the 3D images to detect activity of the larvae. Secondly, tests were performed on dense wooden blocks (30 x 30 x 30 cm, about 20kg) with thick urushi painted layer on the surface using test insects Sitophilus zeamais.
 As a result, it was shown that damaged wooden blocks were effectively treated by CO2 treatment and Vikane® fumigation, but they did not achieve 100% mortality of test insects inside the dense wooden blocks with thick urushi layer.
 From these results, it is supposed that eradication of insects in damaged wooden blocks with no urushi painted surfaces is effective, but large-scale fumigation of the whole building would not achieve 100% mortality of anobiid insects inside the wooden blocks covered with thick urushi layer, especially large pillars 15m in height and with diameter of about 70cm.
 It would also be important to use residual insecticide on the surface (or into some depth) of the wooden pieces, which will be used for the restoration of the building, to prevent further invasion and damage by the anobiids.},
