“…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.…”

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.

“…In the coenagrionid Ischnura elegans , female-deprived males were induced to engage in same-sex activities (van Gossum et al 2005). Both in the pteromalid Lariophagus distinguendus and in the tephritid B. oleae , no advantages were found, since it was reported that male-male courtships are due to weak sex discrimination based on olfactory ambiguity (Ruther and Steiner 2008; Benelli et al 2013). Based on the present study, P. concolor functionally increased courtship intensities.…”

The role of male-male courtship in parasitic Hymenoptera is poorly known. A laboratory study was conducted to assess if Psyttalia concolor (Szépligeti) (Hymenoptera: Braconidae) male courtship can be affected by a previous experience in courting young conspecifics of both sexes. Two experiments were performed to evaluate the effect of experience in courting young wasps on both male courtship and male-male competition behavior. Results showed that a courting experience on both sexes can modify some sexual traits in a P. concolor male, without affecting its success in mating. When approaching virgin females, a P. concolor male that had a previous courtship experience with young wasps of either sex showed shorter latency times, more wing fanning, and longer courtship durations with respect to the control male. The hypothesis that a previous courting experience may allow a P. concolor male to refine its courtship behavior and to enhance courtship intensity in subsequent encounters with females was discussed.

“…As alternative control tools to the chemical insecticides, several biological control agents such as certain braconid species (Wang et al. ; Benelli and Canale ; Canale and Benelli ) as well as plant essential oils (Canale et al. ) were tested with promising results for the control of the olive fly.…”

The olive fly, Bactrocera oleae (Rossi), is the main pest of olive, a host tree that thrives under conditions of high and direct sun exposure. Although the effect of the olive fruit on the reproduction of the fly has been studied to some extent, there is little knowledge on the effect of light. In the present work, we studied the effect of the presence of olive fruit and light intensity on mating and subsequent egg production of olive flies at 25°C and a photoperiod regime of L : D 16 : 8. The results showed that contact of the adults with the fruit, or exposure to fruit odours, favoured both the extent and the duration of mating. This effect was higher at low than at high light intensity. However, egg production following female access to olive fruit was more favoured by high light intensity. Our results also showed that fruit contact and/or volatile fruit stimuli significantly affect mating and egg production of the olive fly, and that this influence is modulated by light conditions. The results contribute to a better understanding of the reproductive behaviour and population dynamics of the olive fly. On a more practical scale, the results provide important insights into how to improve mass rearing of the fly.
