“…Moreover, several studies of polyandrous species have revealed a refractory period (time when females refuse new mating) between successive matings. The length of this period varies widely, from hours to days depending on the species (e.g., in the parasitoid wasp Spalangia endius : King et al., ; in the fruit fly Batrocera cacuminatta and Batrocera Cucumis : Chinajariyawong, Drew, Meats, Balagawi, & Vijaysegaran, ; in the psyllid Bactericera cockerelli : Guedot, Horton, Landolt, & Munyaneza, ; in the spider Paratrechalea ornata : Klein et al., ; and in Batrocera dorsalis : Wei et al., ). A refractory period between mating can be advantageous in terms of fitness, resulting in the female producing more offspring (Wei et al., ).…”

“…In polyandrous species in which females can store sperm in their spermatheca, sperm competition has been found to be a factor of selection (Carazo, Sanchez, Font, & Desfilis, 2004;King, Saporito, Ellison, & Bratzke, 2005;Klein, Trillo, Costa, & Albo, 2014;Schneider, Zimmer, Gatz, & Sauerland, 2016;Scott, 1986).

In many species, males increase their reproductive success by choosing high‐quality females. In natural populations, they interact with both virgin and mated females, which can store sperm in their spermatheca. Therefore, males elaborate strategies to avoid sperm competition. In the terrestrial isopod Armadillidium vulgare, females can store sperm and produce several clutches. Moreover, this species can be parasitized by Wolbachia, which feminizes genetic males, transforming them into functional females. Our study compared attractiveness and mate choice when a male is exposed to both virgin and experienced females (i.e., females who have produced offspring and rested for 6 months), with or without Wolbachia. Our results revealed that males are more attracted to virgin females than experienced females, even if these virgin females are parasitized. Moreover, the chemical analysis highlighted different odors in females according to their reproductive and infection (Wolbachia‐free or vertically Wolbachia‐infected) status. Males attempted copulation more frequently and for longer with virgin females, even if Wolbachia‐infected, while experienced females refused further copulation. The evolutionary consequences of both male choice and female resistance on their fitness are discussed in this study.

“…We investigated how sperm storage is related to mating duration, and whether females may differentially store sperm depending on gift content and presence in the Neotropical nuptial gift-giving spider Paratrechalea ornata (Trechaleidae). Females from this species are polyandrous [ 36 ] and favour matings and longer copulations with males offering nuptial gifts over males without gifts [ 37 ]. Virgin females are less selective, and sometimes accept matings with males that do not offer gifts [ 34 ].…”

“…Virgin females are less selective, and sometimes accept matings with males that do not offer gifts [ 34 ]. However once mated, females radically become more reluctant to additional matings, even when a gift is offered [ 36 ]. Indeed, mated females exert such strong selection on gift-giving behaviour that males that have been rejected and do not have prey available usually collect and wrap inedible items or “worthless gifts” to obtain a mating [ 34 ].…”

Worthless and Nutritive Nuptial Gifts: Mating Duration, Sperm Stored and Potential Female Decisions in Spiders

In nuptial gift-giving species females sometimes select their potential mates based on the presence and size of the gift. But in some species, such as the Neotropical polyandrous spider Paratrechalea ornate male gifts vary in quality, from nutritive to worthless, and this male strategy can be in conflict with female nutritional benefits. In this species, males without gifts experience a reduction in mating success and duration, while males that offer worthless or genuine nutritive gifts mate with similar frequencies and durations. The female apparently controls the duration of copulation. Thus, there is scope for females to favour males offering gifts and further if these are nutritious, via post-copulatory processes. We first tested whether females differentially store sperm from males that offer the highest nutritional benefits by experimentally presenting females with males that offer either nutritive or worthless gifts (uninterrupted matings). Second, we carried out another set of experiments to examine whether females can select sperm based only on gift presence. This time we interrupted matings after the first pedipalp insertion, thus matching number of insertions and mating duration for males that: offered and did not offer gift. Our results showed that the amount of sperm stored is positive related to mating duration in all groups, except in matings with worthless gifts. Gift presence itself did not affect the sperm stored by females, while they store similar number of sperm in matings with males offering either nutritive or worthless gifts. We discuss whether females prefer males with gifts regardless, if content, because it represents an attractive and/or reliable signal. Or alternatively, they prefer nutritive nuptial gifts, as they are an important source of food supply and/or signal of male donor ability.

“…The external silk layer offers to males a better control of the copula, by allowing them to access the female reaction during the sperm transfer by holding the prey gift with the third leg pair (Costa-Schmidt et al 2008;Nitzsche 2011). The inner content seems to be responsible for the main effect of prey gifts is in terms of copula duration, which seems to be associated to both the quality and the size of the inner content (Bruun et al 2004;Albo and Costa 2010;Albo et al 2011;Klein et al 2014). The multimodal interpretation for those components' effects would be of modulation, since the extra control of the males during this stage may represents an increase of the efficiency of sperm transfer, which is mainly defined by the inner content size and/or quality.…”

Cryptic Female Choice in Arthropods

Reproduction is composed by a series of strategies performed by each sex in order to gain control over the outcome of the entire process. Males' attempts to fertilize the females may deal with a hidden factor: the cryptic female choice, which is the females' ability to control fertilization based on males' sexual performance. A particular kind of reproductive strategy adopted by males of several invertebrate orders involves the transfer of substances or materials during the courtship and/or copulation, also known as nuptial gifts (NG). At least nine spider families have representatives that rely on the transfer of NG, all of them classified as oral gifts. Given its appeal in broad areas of behavioral ecology, NG received great attention in terms of their role in determining the outcome of sexual interactions, but little effort was applied toward the integrate analysis of the entire courtship/copulatory process. NGs are obviously just a stage of the entire mate choice process, and the empirical data available supports the idea of sexual conflict. However, I defend that only an integrated analysis will allow us to understand if NG does play some role as a source of information for cryptic female choice, or if it still remains as a way that males found to mitigate the sexual conflict issues.
