“…The effects of male sterility on female remating vary among fruit fly species. Sterile males of A. serpentina and C. capitata are less likely to inhibit female remating (Gavriel et al., ; Landeta‐Escamilla et al., ), while no difference was found for A. fraterculus , Anastrepha ludens (Loew, 1873), B. cucurbitae and B. tryoni (Abraham et al., , ; Arredondo, Tejeda, Ruiz, Meza, & Pérez‐Staples, ; Haq et al., ; Radhakrishnan et al., ).…”

Female remating is a widespread behaviour, reported in several insect species. This behaviour can affect the efficiency of sterile insect technique (SIT); however, little is known about the postcopulatory behaviour of some pest species considered as candidates to be controlled by this technique, such as Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae). In this study, we investigated the effects of male and female sterilization on mating and remating behaviour of D. suzukii. First, we tested the occurrence of multiple mating in different combinations between sterile and fertile males and females. Then, we tested the effects of male and female sterility on female propensity to mate and remate. We found an overall low remating rate by D. suzukii females. Male sterility did not influence mating and remating likelihood; however, copula duration of sterile males was shorter compared to fertile males. On the other hand, sterile females were less likely to mate. Our findings encourage further research regarding the use of SIT to control D. suzukii.

“…Insemination success declines with male age (Harwood et al 2015), sperm viability tends to decline with age in wild flies (Herrera-Cruz M. unpublished data) and older females (35 d-old) have a tendency to store more sperm . Although the exact mechanism by which males inhibit female remating is unknown in this species, there seems to be a synergic effect of both sperm and AGPs (Abraham et al 2014(Abraham et al , 2016.…”

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.

“…Likewise, when sterile males competed with wild males from plum, sterile males had significantly shorter matings compared to wild males (Rull et al, 2012). Reduced copulation duration may be due to the lower quantity of sperm that is transferred by the sterile males [e.g., in A. ludens, Bactrocera tryoni (Froggatt), and Bactrocera cucurbitae (Coquillett), but not A. fraterculus] (Kuba & It o, 1993;Allinghi et al, 2007b;Radhakrishnan et al, 2009;Abraham et al, 2013Abraham et al, , 2016. Reduced copulation duration may be due to the lower quantity of sperm that is transferred by the sterile males [e.g., in A. ludens, Bactrocera tryoni (Froggatt), and Bactrocera cucurbitae (Coquillett), but not A. fraterculus] (Kuba & It o, 1993;Allinghi et al, 2007b;Radhakrishnan et al, 2009;Abraham et al, 2013Abraham et al, , 2016.…”

Nevertheless, the relationship between copula duration and sperm transfer is not always linear (e.g., see Harmer et al, 2006;P erez-Staples et al, 2007;Costa et al, 2012;Abraham et al, 2016). Certainly, for wild A. obliqua males, there is a linear relationship between copula duration and sperm transfer (P erez-Staples & Aluja, 2006;P erez-Staples et al, 2014).…”

Anastrepha obliqua (Macquart) (Diptera: Tephritidae), commonly known as the West Indies fruit fly, is a pest species of mango, plum (both Anacardiaceae), and other commercial crops in various countries in the Neotropics, including Mexico, Central and South America, and the Caribbean islands. Currently, the sterile insect technique (SIT) is used to control this pest. Here, the sexual competitiveness of mass-reared sterile A. obliqua males was evaluated against wild males in field cages. In the first experiment, fertile mass-reared males had similar sexual performance as fertile wild males reared on mango and tropical plum. In the second experiment, sterile mass-reared males had better sexual performance than sterile wild males recovered from mango and tropical plum. In the third experiment, fertile wild males recovered from mango had better sexual performance than sterile mass-reared males. The relative sterility index (RSI) was 0.32, indicating low acceptance of sterile males by wild females. The induced sterility index estimated by Fried's test produced a coefficient of 0.4, indicating that irradiation affected the sexual performance of the mass-reared males, which had reduced sexual performance compared to wild males. We discuss our results in the context of mass-rearing and sterilization as part of the SIT programs used to control A. obliqua.
