Recognition of courtship song in the field cricket, Teleogryllus oceanicus
Article Abstract:
The courtship song of crickets plays a significant role in their mating by evoking mounting responses in females. The effectiveness of the chirp lies in its characteristic temporal pattern. The trill is only partially effective on its own, whereas the chirp component alone can induce normal mounting responses. Amplitude modulation of the chirp rarely affects normal responses. The calling and aggression songs being structurally similar to the courtship, chirps evoke similar responses when played back in a courtship context.

Genotypic variation in calling song and female preferences of the field cricket Teleogryllus oceanicus
Article Abstract:
A common-garden breeding experiment is conducted to determine whether differences between the songs of two populations from the extremes of the geographical and phenotypic distribution have a genetic basis. Differences in the total song duration and the proportion of the long-chirp element in the song remained after five generations of common-garden breeding, indicating that the populations had diverged genetically for these traits.
