“…The difference between both situations could be interpreted as male-male interactions acting against female preferences (Verspoor et al 2015). Here, we showed that when females were given a choice between differently aged males, younger females preferred younger males, whilst older females were less selective.…”

“…In systems where males do not provide parental care, we expect older males to invest more in their ejaculate in terms of sperm or accessory gland products (AGPs) compared to younger males, as older males will have reduced remaining lifetime for future reproductions (Brooks and Kemp 2001;Benowitz et al 2013). For example, in Drosophila pseudoobscura and Drosophila subobscura, females prefer to mate with older males and these females produce more offspring, a direct benefit possibly due to increased investment in sperm, seminal fluids or both (Avent et al 2008;Verspoor et al 2015). In many insects, both sperm and/or AGPs transferred during mating inhibit females from remating (Gillott 2003;Wedell 2005).…”

Female Age Determines Remating Behavior in Wild Mexican Fruit Flies

Male and female age are important factors that can influence mating and remating behavior. Females can discriminate against or prefer older males, but there have been relatively fewer studies on how female and male age influence female remating. Here we showed in wild flies of the Mexican fruit fly Anastrepha ludens (Loew), that when females were given a choice between males of different ages, younger females preferred to mate with younger males over older males, while older females were less selective. Also, when given a choice between males of different ages, older females had longer copulation durations than younger females. On the other hand, older males and females had lower mating success, compared with young and middleaged flies under no choice conditions. However, middle-aged females mated faster compared to young females and young males mated faster compared to middle-aged males. Male age did not influence female remating, while female age strongly determined female remating, with no females remating when they were old. It is unclear if female receptivity mechanisms are switched off at older ages, or if females are reluctant to remate due to possible costs of mating. We discuss our results in terms of how male and female age can influence mating decisions.

Abstract.Recently, there has been rapidly growing interest in the effects of the microbiota on host physiology and behaviour. Due to the nutritional value of bacteria, gut microfl ora may be particularly important in species that present nuptial gifts during courtship. Here, we explore whether the presence or absence of gut microbiota in males and females of the nuptial gift-giving species Drosophila subobscura (Collin, 1936) alters mating behaviour in terms of female preference, male investment, and female fecundity. We found that females that had been fed antibiotics, compared to females with intact gut bacteria, were more willing to mate with a male that had been fed normally. However female fecundity was higher when both males and females lacked gut bacteria compared to both individuals having a full complement of gut bacteria. This implies that the presence of the microbiota acts to reduce female fecundity in this species, and that male gut bacterial content infl uences female fecundity. Our results provide further evidence to the growing consensus that the microbiota of an individual may have important effects on both reproductive behaviour and physiology, and suggest that it may also contribute to the nutritional value of the nuptial gift in this system.
