 note = {Damage by wood borer insects is often observed with wooden objects or wooden historic buildings. X-ray CT (computer tomography) is a non-destructive method　used to look into inside conditions of cultural objects. We tried to observe the change over time of damaged objects using X-ray CT and to detect the activity of some insects. By measuring damaged objects repeatedly, it was found that the activity of some insects was detectable as changes in their position inside the objects.
 Usually, it is not easy to appraise the effect of pest controlling treatment on wood borerinsects in actual damaged wooden pieces. Thus, we tried an application of X-ray CT to learn the effect of treatment in these cases.
 We divided a wooden block which was infected by Priobium cylindricum into two pieces. Only one piece was treated with approximately 60% CO2 for two weeks to eradicate insects. Then the activity of insects in both wooden pieces was observed over time by X-ray CT.
 Changes in the position of insect larvae were clearly shown in the non-treated wooden piece. On the other hand, no change was observed in the treated wooden piece. It was possible to estimate the effect of treatment of insect eradication by comparing the activities of insects over time by X-ray CT.},
