“…In M . domestica It has been proposed to be due to the reduced rate of transfer of accessory gland material in later matings (Leopold et al, 1971). Though L. cuprina males also transfer less accessory gland material with repeated mating, the rate of transfer seems to have no role in determining the duration of copulation in this species.…”

Three manipulations of the male contribution to copulation were used to investigate what determines the switch-off of female receptivity that follows mating in Lucilia cuprina.Multiple matings by males led to a reduction in their effectiveness at switching-off females: the first twelve matings caused more than 50% of females to be switched-off 1 day after mating, while the first four matings caused more than 50% of females to be switched-off for 7 days after mating. Males mated up to twenty-three times and on average ten times during 10 h of continuous access to virgin females. The number of sperm transferred declined logarithmically through a series of matings as did the quantity of material transferred from the male accessory gland (measured as radiolabelled material) through the first six matings. Overnight isolation of multiply-mated males led to considerable recovery of their ability to switch-off females, and to limited renewal of their ability to transfer sperm. Castrated males transferred similar quantities of accessory gland material to females as did sham-operated males during their first five matings and in their first three matings switchedoff 95% of females for 1 day but only 48% for 7 days.When normal mating pairs were separated at increasing intervals after coupling, an increasing proportion of females were switched-off at 1 or 7 days afterward. 7 days after 2 min matings no females were switched-off though 40% of the number of sperm transferred in a full mating had been transferred by this time.The proposed explanation for these data is that both the initial switch-off and its duration are determined by the quantity of a receptivity-inhibiting substance that normally enters the female haemolymph after being injected by the male into the wall of the bursa copulatrix. It is proposed that when castrated males mate, an absence of sperm results in most accessory gland secretion entering the empty spermathecae (rather than the wall of the bursa as usually occurs) and hence being unable to reach the haemolymph and exert its influence. The effective dose of the receptivity-inhibiting substance is measured on a logarithmic scale.

“…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.

“…Waage 1979) and most recently, male accessory gland proteins (Acps) (reviewed in Chapman et al 2000). Acps have been shown not only to increase female oviposition rates (Heifetz et al 2000), facilitate sperm storage (Neubaum & Wolfner 1999;Chapman et al 2000), and incapacitate sperm from previous males (Harshman & Prout 1994;Prout & Clark 2000), but also to reduce mating receptivity (Manning 1962;Leopold et al 1971;Obata 1988;Eady 1995;Miyatake et al 1999) and increase mortality rates (Chapman et al 1995) in mated females. While males stand to benefit from each of these functions, some are clearly deleterious for females.…”

Until very recently, most studies of sperm competition have focused on variation in male competitive ability. However, we now know that a number of reproductive traits, including oviposition rate, use of stored sperm and receptivity to mating, vary with female condition. Because females can play an active part in the movement of sperm within their reproductive tract, sperm competition may be influenced by female condition. Existing studies of sperm competition in fruitflies ignore the effects of female condition, using females that are 3-4 days old and in their reproductive prime. But condition will decline as a female senesces. Here, we examine the effect of female age on the outcome of sperm competition in three strains of the fruitfly, Drosophila melanogaster. Previous studies have shown that female age influences preference for mates and male ejaculation strategies. In this study, we find that when males are mated to females that are older than 17 days, last-male sperm precedence decreases significantly. These results could lead to a greater understanding of the physiological mechanisms that regulate the outcome of sperm competition.
