“…Thus, the hypothesis that females prefer older males despite their reduced fertilization success or viability of their offspring (JONES 2000, JONES & ELGAR 2004 does not seem to apply to C. capitata, at least when there is a choice between young and old males. The data obtained by us is in agreement with other recent studies on different populations of C. capitata (SILVA-NETO et al 2009, SHELLY et al 2011, PAPANASTASIOU et al 2011. Working with the same population used in this study, ANJOS-DUARTE et al (2011b) had found that females did not distinguish between males of 4 and 12 days of age and accepted to mate equally with both; however, they preferred four or 12 days-old males than 20 days-old ones.…”

ABSTRACT. Results of previous investigations trying to ascertain which physiological factors are more important to the mating success of medfly males are controversial. In part, this controversy owes to the fact that each factor was evaluated by an independent study using different experimental designs and populations. In the present study we compare the roles of age and nutritional status (immature and adult phases) on the mating competitiveness of Ceratitis capitata (Wiedemann, 1824) males. Three parameters were used to evaluate the male mating success: calling behavior (pheromone emission), lek participation and copulation (ability to be chosen by a female). Females gave preference to the males that were given a high protein diet in the larval phase. By contrast, females did not give preference to males that had been well-nourished in the adult phase only. The other parameters evaluated followed the same pattern: young males and males that had been fed a high protein diet during their immature phase had a greater participation in leks and called more often than older males and males that had been fed a diet poor in protein during their larval phase.Therefore, we conclude that the mating success of C. capitata males is determined both by age and nourishment during the immature stage.

“…Similarly, in C. capitata, males experienced a drastic decrease in mating performance with age when competing against younger rivals. However, under no choice conditions, males as old as 50-70 d were able to obtain copulations as their younger counterparts (Papanastasiou et al 2011).…”

“…One important issue that complicates comparisons among species and studies is that the terms Byoung^and Bold^do not always mean the same ages. While in some cases the age differences are only a few days, in other cases flies are tested from emergence to senescence (Papanastasiou et al 2011;Benelli et al 2013;Harwood et al 2015). On the other hand, time of sexual maturation differ among species.…”

“…Specially, it can affect copulation duration (Koref-Santibanez 2001;Pérez-Staples et al 2008, mating success (Zuk 1988;Jones 2000;Jones and Elgar 2004;Fricke and Maklakov 2007;Pérez-Staples et al 2010;Papanastasiou et al 2011) and sperm traits (Taylor et al 2001;Pérez-Staples et al 2008;Papanastasiou et al 2011;Costa et al 2012;Decanini et al 2013;Santhosh and Krishna 2013). Females may prefer to mate with young males as they have less deleterious mutations in the germline and are more fertile Price 1995, 1999;Beck and Powell 2000;Beck and Promislow 2007).…”

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.

“…Although age associated changes of male mating success have been addressed in various insect species [18], [22], [23], [24] less attention has been given on effects of age on female sexual and reproductive behaviour [4], [25]. As insects age and senescence prevails the mortality risk increases, fecundity rates decrease [26], and female mating receptivity increases due to progressively limited opportunities of reproduction [27].…”

Condition-Dependent Effects of Mating on Longevity and Fecundity of Female Medflies: The Interplay between Nutrition and Age of Mating

BackgroundIn various species mating exerts direct and indirect effects on female demographic traits ranging from life span shortening to behavioural shifts. A wealth of data regarding effects of nutrition on longevity and reproduction output also exists. Nonetheless, little is known regarding the interaction between the age of mating and nutrition on female fitness.MethodologyWe studied, the effects of protein deprivation and age of mating on female fitness traits, using a wild population of the Mediterranean fruit fly (medfly). We tested the hypotheses that (a) protein availability increases female lifespan and fecundity, (b) female longevity and egg production are independent of mating and the age of mating, and (c) female mating behaviour is independent of their age and nutritional status. Thus, we recorded the mating success and the copulation characteristics, as well as the egg production and survival of females mated at young or at old age and fed a full or a protein-deprived diet.ResultsMating boosts egg production and reduces longevity of protein-fed females. On the contrary, mating increases the longevity of protein-deprived females. Mortality responses (negative or positive) to mating are expressed after a long lag phase. Old females are more receptive and less selective than young females regardless of the food regime.ConclusionsOur findings suggest that condition (nutritional status and age) defines the positive or negative output of mating in female medflies. These results contribute towards understanding the effects of mating, aging, resource allocation and their interactions on survival and female reproduction.
