“…One possible SAC-related function of the movements of the pneumopophyses, suggested by observations of other insects, is that they (at least those with teeth) rub holes in the lining of the female's vagina (Merritt 1989;Crudgington and Siva-Jothy 2000;Flowers and Eberhard 2006). This could allow male seminal products to escape into her body cavity (Gillot and Langley 1981) where they could induce female responses such as sperm transport and resistance to further copulations (Riemann and Thorson 1969;Chen 1984). Previous studies of the reproductive physiology of G. morsitans argue strongly against this alternative, however; introduction of male seminal products into the female's body cavity did not affect ovulation, insemination or remating (Saunders and Dodd 1972;Gillot and Langley 1981).…”

A long-standing mystery in morphological evolution is why male genitalia tend to diverge more rapidly than other structures. One possible explanation of this trend is that male genitalia function as "internal courtship devices," and are under sexual selection by cryptic female choice (CFC) to induce female responses that improve the male's chances of fathering her offspring. Males of closely related species, which have species-specific genital structures, are thought to provide divergent stimulation. Testing this hypothesis has been difficult; the presumed genital courtship behavior is hidden from view inside the female; appropriate experimental manipulations of male and female genitalia are often technically difficult and seldom performed; and most studies of how the male's genitalia interact with those of the female are limited to a single species in a given group, thus limiting opportunities for comparisons of species-specific structures. In this chapter, we summarize data from morphological, behavioral, and experimental studies of six species in the tsetse fly genus Glossina, including new X-ray recordings that allowed visualization of events inside the female during real time. Species-specific male genital structures perform dramatic, stereotyped, rhythmic movements, some on the external surface of the female's abdomen and others within her reproductive tract. Counting conservatively, a female Glossina may sense stimuli from the male's genitalia at up to 8 sites on her body during some stages of copulation. As predicted by CFC theory, these movements differ among closely related species;

“…Andres and Arnqvist (2001) interrupted initial pairs after 30 minutes. Transfer of seminal fluids is complete after 40 minutes (Leopold et al 1971) and the effects of this fluid on female physiology is dose dependent (Riemann and Thorson 1969). Given that allopatry promotes reproductive divergence, the populations may have diverged in the order, timing of transfer, and/or the dosage of components and thus the effects of these chemicals on female physiology may be different.…”

Abstract. Traditional models of sexual selection propose that partner choice increases both average male and average female fitness in a population. Recent theoretical and empirical work, however, has stressed that sexual conflict may be a potent broker of sexual selection. When the fitness interests of males and females diverge, a reproductive strategy that increases the fitness of one sex may decrease the fitness of the other sex. The chase-away hypothesis proposes that sexual conflict promotes sexually antagonistic, rather than mutualistic, coevolution, whereby manipulative reproductive strategies in one sex are counteracted by the evolution of resistance to such strategies in the other sex. In this paper, we consider the criteria necessary to demonstrate the chase-away hypothesis. Specifically, we review sexual conflict with particular emphasis on the chase-away hypothesis; discuss the problems associated with testing the predictions of the chase-away hypothesis and the extent to which these predictions and the predictions of traditional models of sexual selection are mutually exclusive; discuss misconceptions and mismeasures of sexual conflict; and suggest an alternative approach to demonstrate sexual conflict, measure the intensity of sexually antagonistic selection in a population, and elucidate the coevolutionary trajectories of the sexes.

“…After mating, female insects can become temporarily unattractive, they can show reduced receptivity to mating, and they can increase their rate of egg production (e.g., refs. [10][11][12][13][14][15][16][17]. In Drosophila melanogaster females, post-mating responses are elicited by pheromones, sperm, and male ejaculate proteins (reviewed in refs.…”

Mating induces profound changes in female insect behavior and physiology. In Drosophila melanogaster, mating causes a reduction in sexual receptivity and an elevation in egg production for at least 5 days. Injection of the seminal fluid sex peptide (SP) induces both responses in virgin females, but only for 1-2 days. The role of SP in eliciting the responses to mating remains to be elucidated. Functional redundancy between seminal fluid components may occur. In addition, mating with spermless males results in brief (1-to 2-day) post-mating responses, indicating either that there is a ''sperm effect'' or that sperm act as carriers for SP or other seminal fluid components. Here we used RNA interference to suppress SP expression, to determine whether SP is required to elicit full post-mating responses, the magnitude of responses due to other seminal fluid components, and whether SP accounts for the ''sperm effect.'' Receptivity was higher and egg production lower in females mated to SP knock-down males than in controls. Comparison with virgins showed that the responses were brief. SP is therefore required for normal magnitude and persistence of postmating responses. Sperm transfer and use were normal in mates of SP knock-down males, yet their post-mating responses were briefer than after normal matings, and similar to those reported in mates of spermless son-of-tudor males. The prolonged ''sperm effect'' on female receptivity and egg production is therefore entirely attributable to SP, but sperm are necessary for its occurrence.
