Many female insects mate more than once although the adaptive significance is often unclear. We studied the frequency of mating, the fate of the spermatophore, and progeny production of individual females as a function of single or double matings in the house cricket, Acheta domesticus, and the field cricket, Gryllus integer. Females of both species may mate repeatedly and often eat the externally attached spermatophore. In A. domesticus, doubly mated females produced significantly more offspring than did single maters, the difference resulting largely from the failure of 12.5% of the single maters to leave progeny. Singly and doubly mated G. integer did not differ regarding nymph production, but 50% of the singly mated females did not reproduce. Remating by female crickets partly functions in offsetting the probability of a failed initial mating. Nymph production increased significantly with the time the spermatophore was attached in singly mated A. domesticus. Spermatophore consumption by the female was not affected by male "guarding" behaviour, and the interval between mating and eating of the spermatophore may often be shorter than the time required for maximum insemination. It is suggested that acquisition of nutrition may be an additional function of female repeated matings.

AbstractBehaviors are often correlated within broader syndromes, creating the potential for evolution in one behavior to drive evolutionary changes in other behaviors. Despite demonstrations that behavioral syndromes are common across taxa, whether this potential for evolutionary effects is realized has not yet been demonstrated. Here we show that populations of field crickets (Gryllus integer) exhibit a genetically conserved behavioral syndrome structure despite differences in average behaviors. We found that the distribution of genetic variation and genetic covariance among behavioral traits was consistent with genes and cellular mechanisms underpinning behavioral syndromes rather than correlated selection. Moreover, divergence among populations’ average behaviors was constrained by the genetically conserved behavioral syndrome. Our results demonstrate that a conserved genetic architecture linking behaviors has shaped the evolutionary trajectories of populations in disparate environments—illustrating an important way by which behavioral syndromes result in shared evolutionary fates.

Evidence of natural selection for certain aspects of mating efficiency in swine are advanced based on preliminary studies with thirty-one sires, fiftyeight dams and their progeny. Selective fertilization was conclusively demonstrated. Variations in male and female mating behaviour were sufficiently large to indicate considerable non-randomness of mating frequency under the conditions of multiple sire mating (i.e. group exposure of dams to selected sires). The combined effects of the separate phenomena of selective fertilization and mating behaviour are discussed in relation to their evolutionary significance in animal breeding.
