“…In such a femalebiased condition, females would favor multiple matings because of the increased risk of mating with males who have exhausted their sperm supplies after many matings. Studies with quasi-gregarious species, where each individual develops in a separate host but females produce femalebiased sex ratios (because the hosts are distributed in clumps), have shown that females accept multiple matings and have indicated that a certain percentage of females mate with sperm-depleted males (Jacob and Boivin 2005;Santolamazza-Carbone and Pestana 2010). Furthermore, our model predicts that an evolutionarily adaptive change would be for males to partition their sperm budgets to deliver sperm to a large number of females (we verified that our general predictions are unchanged for populations with local patches consisting of a restricted number of individuals).…”

Sperm Economy between Female Mating Frequency and Male Ejaculate Allocation

Why females of many species mate multiply is a major question in evolutionary biology. Furthermore, if females accept matings more than once, ejaculates from different males compete for fertilization (sperm competition), which confronts males with the decision of how to allocate their reproductive resources to each mating event. Although most existing models have examined either female mating frequency or male ejaculate allocation while assuming fixed levels of the opposite sex's strategies, these strategies are likely to coevolve. To investigate how the interaction of the two sexes' strategies is influenced by the level of sperm limitation in the population, we developed models in which females adjust their number of allowable matings and males allocate their ejaculate in each mating. Our model predicts that females mate only once or less than once at an even sex ratio or in an extremely female-biased condition, because of female resistance and sperm limitation in the population, respectively. However, in a moderately female-biased condition, males favor partitioning their reproductive budgets across many females, whereas females favor multiple matings to obtain sufficient sperm, which contradicts the predictions of most existing models. We discuss our model's predictions and relationships with the existing models and demonstrate applications for empirical findings.

“…Females rendered unreceptive as a result of the post‐copulatory ritual, as shown for Aphytis melinus (DeBach) (Allen et al., 1994), may benefit further from the post‐copulatory ritual if it prevents additional matings, which could make females adjust the sex ratio of her offspring toward more or only sons (Flanagan et al., 1998; Jacob & Boivin, 2005; Santolamzza‐Carone & Pestana, 2010).…”

Males and females of the parasitoid wasp Ooencyrtus kuvanae (Howard) (Hymenoptera: Encyrtidae) emerge en masse from gypsy moth, Lymantria dispar dispar (L.) (Lepidoptera: Noctuidae: Lymantriinae), host egg masses. Males engage females in a brief pre‐copulatory ritual, mate, and then execute a post‐copulatory ritual. We investigated mechanisms, functions, and fitness consequences of the pre‐ and post‐copulatory ritual by high‐speed cinematography, gas chromatographic‐mass spectrometric analyses of volatile constituents on the insects’ integument, and behavioral assays. Our data indicate that the mechanisms of the pre‐ and post‐copulatory ritual are physical interactions rather than pheromone transfer. During the pre‐copulatory ritual, the males put females into a trance‐like state that persists for some time after copulation. Males attained a mating with in‐trance females 9.5 times faster than with females that had come out of trance. Mated females with post‐copulatory ritual experience did not remate, whereas females lacking that experience did. The total number of offspring and daughters did not differ between females with or without post‐copulatory ritual experience or in relation to the duration of that ritual. The post‐copulatory ritual functions as a form of mate guarding in that the male accelerates awakening of the in‐trance female, which then rejects mating attempts by other males, ensuring his paternity.

“…Male offspring of the polyandrous vole Myodes glareolus (Schreber) (Rodentia, Cricetidae) and Teleogryllus oceanicus (Le Guillou) (Orthoptera: Gryllidae) are competitively superior to male offspring produced by monandrous parents (Kawazu et al, 2014 ; McNamara et al, 2014 ). However, offspring of other species, including Cadra cautella (Walker) (Lepidoptera: Pyralidae) and Anaphes nitens (Girault) (Hymenoptera: Mymaridae), do not appear to derive any benefit from female multiple matings (McNamara & Elgar, 2008 ; Santolamazza‐Carbone & Pestaña, 2010 ).…”

Polyandry, which is widespread throughout many taxonomic groups, occurs when females mate with more than one male (Byrne & Whiting, 2011). However, females will often incur various costs of mating through increased risk of injury, disease, and predation (Ivy & Sakaluk, 2005). Nevertheless, the mating frequency of females often exceeds the number of copulations required for fertilization.In fact, a single mating is frequently sufficient for females to fertilize their entire complement of eggs and to maximize their reproductive
