Title: Food fight: Sexual conflict and the evolution of nuptial food gifts.

Abstract: Sexual conflict occurs whenever the reproductive strategy pursued by one sex poses a selective disadvantage to the other. In crickets, the evolutionary interests of the sexes often collide over the paternity of offspring: because the ejaculate of a male typically remains outside the female's body after mating in the form of an externally attached spermatophore, female are well positioned to determine the fate of their mates' gametes through their selective removal of males' spermatophores. Because it is in the interests of males to have all of their sperm utilized in fertilizations, female spermatophore removal is often at odds with the reproductive interests of their sexual partners. Nuptial food gifts, an integral feature of the mating systems of a wide variety of insects, may be a frequent conduit by which males attempt to influence the mating behavior of females against females' own reproductive interests. Recent work in my laboratory suggests that the food gifts offered by male decorated crickets contain substances that are designed specifically to appeal to females' tastes, but which also contained receptivity-inhibiting compounds. These results support a recent suggestion that food 'gifts' are in fact 'Medea' gifts, male refractory-inducing substances disguised as nutritional offerings.
