 note = {Damage by wood borer insects is often observed on wooden objects or wooden historic buildings. When we guess levels of damage inside the wooden objects, holes on the surface of wood or powders from the holes are important clues in accessing damage by observation. Sometimes “active” infestation is strongly suggested by the emergence of insects from the wooden holes, or by continuous production of wooden powders including insect frass and droppings. Though such observation is important, methods to observe the inside of objects would also be very effective in estimating the level of damage. X-ray CT (computer tomography) scanning is one of such non-destructive methods to look into conditions inside cultural objects. In
this study, we were able to obtain very good images of insects and the damaged parts inside the wooden objects.
 First, as a preliminary test, larvae of a dermestid (Attagenus japonicus) or their casting skins were put into two wooden pieces respectively. Consequently, only larvae were detected very clearly by CT in the wooden piece, but casting skins showed no significant signal. This suggested that active larvae (or insect bodies in similar condition) can be detected by CT probably owing to differences in density.
 Then we observed the damaged structural wooden pieces from Rinnohji temple of Nikko (World Heritage) infested by a rare kind of anobiid, Priobium cylindricum. As a result, insects were detected inside the pieces very clearly. Also clear images of damaged parts inside the wooden pieces were shown. Such information would be important to know the characteristics of damage by the rare insect species, about which we do not have enough information for now.},
