“…Further, risk of sperm competition could be considered equivalent for all males in this experimental setup, since males had the opportunity of choosing between three virgin females from the same batch of insects. Thus, these are strong indications to suggest that the variability in sperm investment of B. oleae males could be attributed to cryptic male choice for females of higher reproductive value (Kelly and Jennions 2011;Pérez-Staples et al 2014). a b Fig.…”

Polygynous males must balance their limited ejaculate resources between current copulations, with putative future ones. Working on olive flies (Bactrocera oleae), our objectives were to determine (a) how males budget sperm to consecutive copulations, (b) what costs consecutive copulations incur, and (c) how male mating history affects female fecundity, fertility, and longevity. We allowed males to copulate with virgin females on successive days and monitored the fertility and fecundity of these females, and the longevity of both sexes. We found that as males gained sexual experience, latency to mate declined significantly, while copula duration increased. The number of sperm stored by females declined according to the sexual history of her mate-as males gained experience, significantly fewer sperm cells were transferred. Mated males suffered a significant longevity cost compared to virgin ones, but this cost was not compounded by additional matings. Male sexual experience affected both female fecundity and fertility. Furthermore, mating with an experienced male incurred a longevity cost to females. We conclude that non-sperm components of the male ejaculate are responsible for reducing female fecundity, fertility, and longevity, and predict that females should prefer to mate with virgin males.

“…Also, sterile males of C. capitata had significantly shorter copulation durations than wild fertile males (McInnis et al, 2002), and in Anastrepha fraterculus (Wiedemann), copulation duration was reduced as a result of irradiation (Allinghi et al, 2007a). 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). However, this has not been assessed in sterile A. obliqua.…”

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.

Studies on how tephritid females can detect differences in the fertility status of males will be useful where SIT is included for their control and will help to elucidate female choice mechanisms during copulation.…”

The sterile insect technique (SIT) has been used successfully for the control of fruit flies. The efficiency of this technique can be significantly reduced when sterile released insects are exposed to adverse conditions and predators, as a great number of sterile insects die before reaching sexual maturity and thus fail to mate with wild females. Treatments with juvenile hormone (JH) analogues such as methoprene (M) significantly reduce the time to reach sexual maturity by sterile Anastrepha ludens (Loew) (Diptera: Tephritidae) males. In this study, we compared the sexual performance of non‐treated sexually mature males with young males that had been sexually accelerated with M. Furthermore, we compared the ability of M‐fed males in inhibiting female remating compared with sexually mature males. Results showed that at 5 days M‐fed males had lower mating success than mature males; however, 6‐day‐old (0.1%) M‐fed males had the same amount of matings as mature 13‐day‐old males. Young 5‐ to 10‐day‐old M‐fed males also had similar number of matings as mature non‐treated 12‐ to 17‐day‐old males. There were no differences in copula duration between treatments. Moreover, there were no differences between the fertility, fecundity or refractory period of females mated with either young male fed M or normal sexually mature males. These results indicated that young males that were sexually accelerated with M have the same sexual performance as non‐treated sexually mature males. Implications of using M as a pre‐release treatment for A. ludens controlled through SIT are discussed.
