1. Males of Gryllotalpa australis (Erichson) (Gryllotalpidae) and Teleogryllus commodus (Walter) (Gryllidae) produced their calling songs while confined in respirometers.

2. G. australis males used oxygen during calling at a mean rate of 4.637 ml O2 h\−1, equivalent to 27.65 mW of metabolic energy, which was 13 times higher than the resting metabolic rate. T. commodus males used oxygen during calling at a rate of 0.728 ml O2 h\−1, equivalent to 4.34 mW, which was four times the resting metabolic rate.

3. The sound field during calling by males represents a sound power output of 0.27 mW for G. australis and l.51 \× l0.3 mW for T. commodus.

4. The efficiency of sound production was 1.05\% for males of G. australis and 0.05\% for males of T. commodus. Comparison with other insect species suggests that none is more than a few percent efficient in sound production.

The stridulatory apparatus of Gryllus fulvipennis is described based on light microscopy and SEM. Audiospectrography analysis of the song calls of this species is presented; each one of the chirps is composed of 4 or 3 syllables. The initial syllabes is shorter than the other, and its duration is ca 16 ms, the range of frequency is shorter too. The regularity and constancy of the pattern of syllabes from chirps, support the presumption that the friction is only in one direction.
