Mate Quality and Novelty Influence Post-Copulatory Female Choice in Decorated Crickets, Gryllodes sigillatus
Females of numerous animal taxa can secure important indirect genetic benefits by mating multiply, either by increasing the genetic diversity of their offspring, acquiring ‘good genes’, avoiding genetic incompatibility, or diluting inbreeding effects (Jennions & Petrie 2000; Kokko et al. 2002; Zeh & Zeh 2003). Only by mating with different partners, however, can females secure the diverse ejacu...
متن کاملPost-copulatory mate guarding in decorated crickets
Although post-copulatory mate guarding occurs in a variety of crickets, its adaptive significance remains largely unknown. Mate guarding may function to prevent females from prematurely removing the externally attached sperm ampulla, thereby ensuring maximum insemination. This hypothesis was tested in decorated crickets, Gryllodes supplicans, by comparing ampulla retention times of females guar...
متن کاملHeritable variation in the timing of spermatophore removal, a mechanism of post-copulatory female choice in crickets.
Female crickets can exert post-copulatory mating preferences by prematurely removing a male's spermatophore after copulation, which terminates sperm transfer. Although most models of sexual selection assume that female mating preferences are heritable, there has been little work addressing genetic variation underlying post-copulatory mate choice. We used a paternal half-sib design, in which dif...
متن کاملAcoustic experience shapes female mate choice in field crickets.
Female choice can drive the evolution of extravagant male traits. In invertebrates, the influence of prior social experience on female choice has only recently been considered. To better understand the evolutionary implications of experience-mediated plasticity in female choice, we investigated the effect of acoustic experience during rearing on female responsiveness to male song in the field c...
متن کاملVirgin-malemating Advantage in Sagebrush Crickets: Differentialmale Competitiveness or Non-independent Femalemate Choice?
Female sagebrush crickets (Cyphoderris strepitans) feed on males’ eshy hind wings during copulation and ingest haemolymph oozing from the wounds they in ict. The wounds are not fatal and usually only a portion of the hind wings are eaten at any one mating, so that mated males are not precluded from mating again. However, based on their relative abundance in the population, virginmales have a...
