Studies were carrred out on the sounds produced by Japanese pine sawyer larvae. The duration of sounds alternating with silent phases, intervals between sound-units, and wave form and intensities of sound-units were studied, and larval sound producing behavior was observed. The duration of one continual sound production did not exceed five min and shortened with the progression of larval development. Intervals between two sound-units were approximately two sec and nearly constant throughout larval development. Sound-units lasted nearly 0.04 sec in length and consisted of more than 10 wave trains which were around 0.001 sec in length. The intensity of sound pressure exceeded 40 dB and the sounds were clearly audible at more than 15 m from the sound source in a pine stand during good weather conditions. Larvae were also observed revealed to produce sound from a posture contacting mandibles with gallery walls.
