Lovesick: 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 کاملLovesick: 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 کاملSexual selection on cuticular hydrocarbons of male sagebrush crickets in the wild.
Cuticular hydrocarbons (CHCs) play an essential role in mate recognition in insects but the form and intensity of sexual selection on CHCs has only been evaluated in a handful of studies, and never in a natural population. We quantified sexual selection operating on CHCs in a wild population of sagebrush crickets, a species in which nuptial feeding by females imposes an unambiguous phenotypic m...
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...
