| Summary: | In this thesis I investigate acoustic signalling and mate choice in the field crickets Giyllus bimaculatus and Gryllus campestris. I measured female response to calling song and courtship song In G. bimaculatus to address a number of questions. I looked at intrinsic factors affecting female mate choice by measuring female response to calling song throughout their reproductive lives and examining the effect of mating. I found that female choosiness but not magnitude of response to calling song was affected by age. I also found that non-virgin females were as choosy as virgin females but responded less. These results suggest that female choice is temporally plastic and that choosiness is costly. |
