Lovesick: immunological costs of mating to male sagebrush crickets.
A growing body of evidence suggests that resources invested in reproduction often come at the expense of the ability to mount an immune response. During mating, female sagebrush crickets, Cyphoderris strepitans, consume the ends of the male's hind wings and ingest his haemolymph. Previous research has shown that this behaviour impairs the ability of males to secure additional matings. One hypot...
متن کاملLovesick: Immunological Costs of Mating of Male Sagebrush Crickets
A growing body of evidence suggests that resources invested in sexual signals and other reproductive traits often come at the expense of the ability to mount an immune response. Male sagebrush crickets, Cyphoderris strepitans, offer an unusual nuptial food gift to females during mating: females chew on the tips of males' fleshy hind wings and ingest hemolymph seeping from the wounds they inflic...
متن کاملCoping with the cold: temperature and mating activity of male sagebrush crickets Cyphoderris strepitans (Orthoptera: Haglidae)
The effect of temperature on male sexual displays is well documented but its role in mediating the differential mating success of males is less well established. Male sagebrush crickets Cyphoderris strepitans Morris and Gwynne occur in high-elevation sagebrush meadows in mountainous areas of the western U.S.A., and often are observed singing at temperatures as low −8 to −4 °C to attract sexuall...
متن کاملIngestion of male haemolymph and mating propensity of female sagebrush crickets: no evidence of a male-derived antiaphrodisiac
Male sagebrush crickets, Cyphoderris strepitans, offer an unusual nuptial food gift to females during copulation: females feed on the hindwings of males and ingest haemolymph seeping from the wounds they inflict. Previous work has shown that females prevented from wing feeding during initial copulations are more receptive to subsequent matings than females permitted to wing feed. In the present...
متن کاملSize-dependent response to conspecific mating calls by male crickets.
Male sexual displays provide females with information that is crucial to their reproductive decisions. That same information is available to eavesdroppers, with potential consequences for both signaller and receiver. We present empirical evidence for size-dependent responses to intersexual communication by conspecific rivals. Acoustic features of a male house cricket's (Acheta domesticus) matin...
