Variability in call structure and pairing success of male field crickets, Gryllus bimaculatus: the effects of age, size and parasite load
Article Abstract:
The effects of age, size and parasite load on the call structure and pairing success in male field crickets (Gryllus bimaculatus) is investigated. Results show that females prefer older males, and this is ironical because mating success decreases with age. Moreover, males with lower levels of gregarine infections are more likely to be paired, but this is true only for young males. Finally, the syllable ratewithin male calls is negatively related to male size, and male size does not influence pairing success.

Male potential reproductive rate influences mate choice in a bushcricket
Article Abstract:
Nutrient limitation imposes a limit on the paternal investment in bushcrickets, Requena verticalis. This limitation induces males to be more discriminating in their mate choice. Males discriminate against older females assumed to have mated previously. The analysis of the influence of male fitness and the variance in female quality on the mate choice of male bushcrickets reveal that costs and not benefits determine mate choice.

Immune function reflected in calling song characteristics in a natural population of the cricket Teleogryllus commodus
Article Abstract:
The calling song parameters in a natural population of the cricket Teleogryllus commodus are examined. The connection between sexual signaling and immune function in a natural population of insects and lends support to the immunocompetence handicap hypothesis.
