| Research Abstract |
I investigated vibrational responses and associated sense organs in the Japanese pine sawyer beetle, Monochamus alternatus. This beetle showed behavioral responses, such as freezing, to vibrations with low frequencies below 1 kHz. The femoral chordotonal organ was found to detect low-frequency vibrations. Weakened pine trees that are suitable for oviposition of the beetle emit spontaneously low-frequency vibrations. The beetle can detect the vibration from the tree and select the tree for oviposition.
