“…In C. capitata , virgin females live longer than non-virgin females (Chapman et al 1998), while female Drosophila that mate at high frequencies have shortened life spans (Fowler and Partridge 1989), largely due to the transfer of toxic Sfps (Chapman et al 1995). Both C. capitata and Drosophila females mate multiply (Markow 1996, Kraaijeveld and Chapman 2004) and it has been suggested that the reduced female longevity after mating is a side-effect of evolutionary conflict between the sexes (Chapman et al 1995). Ae.…”

Male Mating History and Body Size Influence Female Fecundity and Longevity of the Dengue Vector Aedes aegypti

Male reproductive success is dependent on insemination success and reproductive output. During mating, male mosquitoes transfer not just sperm, but also seminal fluid proteins that may have profound effects on mated female biology and behavior. In this study, we investigated the role of male body size and mating history on semen depletion, female longevity and reproductive success in Aedes aegypti L. Small and large males were mated in rapid succession with up to five females. Our results indicate that large males had greater mating capacity than small males. A reduction in fecundity by more than 50% was observed in females that were fourth to mate with small males in comparison to females that mated earlier in sequence. For females mated to large males, this reduction became evident for females that mated fifth in sequence. No loss of fertility (measured as hatch rate) was observed in females that were 3rd-5th in mating sequence compared to females mated to virgin males. When females were maintained on a low-quality (5% sucrose) diet, those mated to virgin males had a greater longevity compared to females mated third in sequence. We conclude that small males experience more rapid seminal depletion than large males, and discuss the role of semen depletion in the mated female. Our results contribute towards a better understanding of the complexity of Ae. aegypti mating biology and provide refined estimates of mating capacity for genetic control efforts.

“…An indirect observation supporting this hypothesis is the lower percentage of Israeli females ovipositing (15% in September and 30% in AprilÐMay). In C. capitata females, the receptivity to a second mating has been reported to negatively correlate with female age (Chapman et al 1998, Kraaijeveld andChapman 2004). Moreover, mated males seem to be more efÞcient at inhibiting remating than virgin males (Vera et al 2002).…”

“…The C. capitata control programs based on SIT rely on the release of mass-reared, sterilized males into the target wild population, which should mate with wild females reducing the production of viable offspring (Knipling 1955). Kraaijeveld and Chapman (2004) showed that the low mating competitiveness of sterile males increases the probability of fertile matings. Although a high remating rate may exacerbate the problem of the low mating success of sterile males, the level/direction of paternity skew may add further uncertainties to be considered along with population variation in the overall mating behavior.…”

“…Whether remating and sperm use could be inßu-enced by geographic or genomic variation is still an open question. Moreover, from an applied perspective, different levels of polyandry may locally have an effect on the efÞcacy of the sterile insect technique (SIT) (Kraaijeveld and Chapman 2004), which is currently the most commonly applied control strategy against C. capitata (Krafsur 1998).…”

In many insect species, females can mate more than once and store sperm from more than one male. An assessment and understanding of polyandry in the field can be important for pest species with a high colonization potential, such as the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), which is also highly polyphagous and among the most destructive agricultural insects. The use of polymorphic microsatellite markers, combined with different statistical approaches, provides evidence that polyandry occurs in two C. capitata natural populations, one population from the Greek island of Chios and one population from Rehovot, in Israel. The observed different level of polyandry is discussed in relation to the genetic diversity, seasonality, and demography of the two populations. When polyandry is present, paternity analysis also indicates that one male, presumably the last, tends to sire most of the progeny. Polyandry and paternity skew may have important implications for the evolution of the species, in terms of maintenance of the genetic variability. Moreover, these aspects of the mating behavior, i.e., remating frequency and paternity skew, may locally affect the sterile insect technique, the most commonly applied control strategy against C. capitata.

“…In general, the sperm of irradiated males have a lower fertilizing ability than those of normal males (Simmons 2001). In Mediterranean fruitfly, Ceratitis capitata, irradiated males mate less successfully with both virgin and nonvirgin females and are less effective at preventing or inhibiting female remating than normal males (Kraaijeveld and Chapman 2004).…”

P 2 , the proportion of offspring sired by the second male to mate, is an indicator of the outcome of postcopulatory sexual selection, which occurs through sperm competition and/or cryptic female choice. We determined the appropriate dose of gamma radiation for sterilization of adult males and, using the sterile male technique, measured P 2 in the adzuki bean beetle, Callosobruchus chinensis. Adult males of C. chinensis were almost completely sterilized when irradiated at 80 Gy. Thus, we obtained sterile males through irradiation at this dose. Neither the probability of female first mating nor the probability of female remating was affected by whether females were paired with normal or sterile males. The P 2 calculated from the hatching success of eggs laid by females that mated both with normal and sterile males did not differ between reciprocal mating sequences, indicating that the sterilization has no effect on sperm fertilizing ability. The P 2 was estimated at 0.25. This study shows that female remating in C. chinensis means the coexistence of sperm from two males and thus the occurrence of postcopulatory sexual selection within the female reproductive tract, resulting in first-male sperm precedence.
