为了将声发射（AE）监测应用于竹粉柱甲虫（dinoderus minuusus）在竹竿内的摄食生物学的无损连续分析，有必要明确其摄食活动与声发射产生之间的关系。在本研究中，研究了大蠊幼虫和成虫的行为。在显微镜下直接观察毛竹（Phyllostachys bambusoides）试样的声发射，同时对附着在共振频率为150 kHz的声发射传感器上的试样进行声发射测量。幼虫或成虫的下颌骨在进食活动中表现出“咀嚼运动”。当幼虫或成虫用下颌骨咀嚼标本时，检测到AE撞击。在测量条件下，产生AE击中的下颌骨咀嚼运动占幼虫咀嚼运动总量的26 - 42%，占成虫咀嚼运动总量的27 - 43%。另一方面，当幼虫或成虫不咀嚼标本时，几乎没有检测到AE命中。因此，声发射的产生与d.m minuus下颌骨的咀嚼运动相对应。
In order to apply acoustic emission (AE) monitoring to the non-destructive and continuous analysis of the feeding biology of the bamboo powder-post beetleDinoderus minutusinside bamboo culms, it is essential to clarify the relationship between their feeding activity and AE generation. In this study, the behavior of the larva and adult ofD.minutusin a madake (Phyllostachys bambusoides) specimen was directly observed by a microscope, while AE measurement of the specimen attached to an AE sensor (150 kHz resonant frequency) was conducted simultaneously. The mandibles of the larva or the adult exhibited “chewing movements” when it was in feeding activity. AE hits were detected as the larva or adult chewed the specimen with its mandibles. Under the measurement conditions employed, chewing movements of the mandibles that produced AE hits accounted for 26–42 % of the total chewing movements for larvae, and 27–43 % for adults. On the other hand, when the larva or adult was not chewing the specimen, almost no AE hits were detected. Therefore, the generation of AE corresponded to the chewing movements of the mandibles ofD.minutus.
