“… 1. Pre‐reproductive death: instances where females die before becoming functionally reproductive [long physiological maturation period (van Buskirk, 1987; Anholt, 1991), adult diapause (Popov & Veerman, 1996; Baer & Schmid‐Hempel, 2005; Kobayashi & Osakabe, 2009), migration events (Torres‐Vila & McNeil, 2001; Zhao et al., 2009), or limited access to resources essential for breeding (Ahnesjö et al., 2001)]. 2. Mating failure: instances where females become functionally reproductive adults but fail to mate due to lack of opportunity (Rhainds et al., 1995a; Sharov et al., 1995).…”

Empirical and experimental studies reporting the probability that some females remain unmated in field populations of insects (defined herein as mating failures) are reviewed in more than 100 species. The techniques used to quantify mating failures in the field are summarized, as well as factors that influence the probability that females mate during their lifetime. The existing empirical data provide partial support for hypotheses generated by theoretical models, although the trends observed in field populations are far more diverse and complex than predictions derived from ecological theory, e.g., the effect of population density on female mating success at small and large spatial scales is opposite. Mating success of females increases with the ratio of males in the population, but the relation between emergence time, sex ratio, and female mating success is variable. Females have evolved a broad range of physiological and behavioural adaptations to reduce mating failures, and exhibit a flexible context‐dependent response to constraints limiting mating success. The large number of studies in Lepidoptera suggests a higher mating success in butterflies than moths. Examples of high rates of mating failure include species with gynogenous reproduction, long range migration, pre‐reproductive maturation, male‐biased sex ratio, acquisition of resources essential for reproduction, and female flightlessness. Species with sessile females that mate and oviposit near their emergence site provide model systems to investigate the causes and demographic consequences of female mating failure.

“…Leon‐Beck & Coll () revealed that Orius laevigatus (Fieber) females are monandrous and males of the species are polygamous. In contrast, Kobayashi & Osakabe () demonstrated that Orius sauteri (Poppius), Orius strigicollis (Poppius), and Orius nagaii Yasunaga females displayed multiple mating with several males. If the genus Orius includes both polyandrous and monandrous species, it is worthwhile to compare the mating systems of closely related species in order to help clarify the evolution of polyandry.…”

We compared the mating systems and genital morphology of three Orius species dominant in Japan: Orius sauteri (Poppius), Orius minutus (L.), and Orius strigicollis (Poppius) (Heteroptera: Anthocoridae). In all three species, the males were polygamous and could inseminate at least three females at a rate of one female per day. Compared to the other two species, the O. minutus males had a lower rate of success in three consecutive mating orders. The mated females laid the same number of eggs irrespective of mating sequence. Orius minutus and O. strigicollis females were found to be monandrous, and they re‐mated with another male only when the 1st mating failed. In contrast, O. sauteri females were polyandrous and accepted a 2nd male even when the 1st mating was successful. Multiple mating with a single male did not increase their fecundity, and it decreased the hatching success of eggs. Mating with multiple males did not affect the fecundity or hatching success. Our scanning electron microscopy observation suggested that the genitalia of O. minutus and O. strigicollis were more similar in shape. The similarities in mating system and morphology between O. minutus and O. strigicollis support a close phylogenetic relationship.

“…In Dunedin, not only did we observe several live nymphs and adults of both sexes, but also two copulating pairs at night, when temperatures were comparable to other sites (+3.3˚C). This suggests N. annulata is capable of continuous reproduction throughout the year, rather than mating seasonally, as is observed in many other insects (Kobayashi & Osakabe 2009;Tauber et al 1986).…”
