<p>In this study, we demonstrate that substrate-borne vibrations induced tonic immobility or startle responses in the adults of the sap beetle Phenolia（Lasiodites）picta（MacLeay）. Most of the tonic immobility and startle responses were induced by large accelerations of vibrations with 8.0 and 16.0 m/s2 at frequencies of 60 and 120 Hz. We also observed that tonic immobility and startle responses during walking were affected by three different intervals（1.0, 4.0, and 9.0 s）of pulsed vibrations with 1.0-s durations at 120 Hz and 8.0 m/s2. All intervals of vibrations showed increased numbers of tonic immobility and startle responses, and they showed decreased durations of walking, compared with control stimulus with continuous vibrations and that without vibrations. In addition, long interval of 9.0 s induced highest rate of tonic immobility and startle responses per pulsed vibration among the three intervals. A negative relationship with walking durations was detected in the numbers of tonic immobility and startle responses. These results suggest that short intervals of vibrations decrease the induction of tonic immobility and startle responses due to habituation.</p>
