Search behaviour and mate choice by female field crickets, Gryllus integer

Article Abstract:

Female field crickets, Gryllus integer, could potentially use a search tactic involving the recall of potential mates, according to research designed to establish whether females are capable of recalling, in the absence of a signal, the location of a previously encountered male under conditions in which two males are sampled while seeking a mate. It was found that females that come into direct contact with a male and then sample an additional potential mate a short distance away are likely to be capable of returning to mate with the individual encountered first when there is no audible signal.

Evidence for adaptive chances in egg laying in crickets exposed to bacteria and parasites

Article Abstract:

A study was conducted to investigate the changes in egg laying will crickets injected with bacteria and parasites will adapt. Results reveal that crickets exposed to a pathogen and/or a parasite increased their reproductive output the day after they were exposed to the infection. It was proven that this behavior is not effected by physical stress nor an undetermined response to the infection. Rather, the increase in egg output is a form of adaptive behavior caused by the crickets' anticipation that their chances for future reproduction are low.

Phenotypic variation in the mating preferences of female field crickets, Gryllus integer

Article Abstract:

A study has been conducted to examine mating behaviour in female field crickets, Gryllus integer, in relation to the male's ability to produce trilled calling song. Females preferred male calling songs with more pulses per trill and shorter inter-trill intervals and increased with the number of pulses per trill in the song. They also preferred stronger trills and a higher proportion of missing pulses.
