“…Mating plugs blocking the female reproductive tract have been found in a number of insects (Thornhill and Alcock, 1983;Lachmann, 1998). In Lygus hesperus a mating plug was also described when Strong et al (1970) noted a substance "which fills the genital pouch after mating, similar to that found only in the medial pair of male accessory glands", although this was not identified as a mating plug or as part of a spermatophore. Mating plugs have also been described in Rhodnius bugs (Davey, 1960).…”

“…So far, sex pheromone emission has not been related to female mating status in this group of insects, although polyandry is found in some mirids (Smith, 1977;Chatte rjee, 1983;Strong et al, 1970), as well as in pentatomid bugs (Mitchell and Mau, 1969;McLain, 1985;Kawada and Kitarnura, 1983;Wang and Millar, 1997). In Lygocorispabulinus (L.), (Heteroptera: Miridae) polyandry has been observed in the laboratory, also on consecutive days (Groot et al 1998).…”

Lygocorispabulinus females are polyandrous under laboratory conditions (Groot et al., 1998). As the insect mating system affects sexual communication and thus sexual behavior as a whole, we studied sperm transfer, storage and displacement in L. pabulinus. To be able to fully understand these processes, detailed information on the female reproductive tract is essential. Therefore, we first studied the female genitalia in detail. The bursa copulatrix consists of four plates, and a spermatheca is connected anteriorly to the bursa. At copulation a spermatophore is formed in the spermatheca. The spermatophore is compartmentalized, consisting of a spermcontaining portion, a large sperm-free portion and a mating plug. After 24 h the spermatophore has partially disintegrated. The mating plug is still intact but reduced in size. Sperm are found throughout the spermatheca and in the median and lateral oviducts where fertilization most likely takes place. The amount of male-derived substances transferred to females during first matings was ca. 5.2% relative to male body weight. To understand the effects of matings on the sexual communication, we determined sexual attraction of mated females at long and close range. At long range females were unattractive for only 1-2 h after mating, while they remained attractive at close range. Mated males were not attracted to virgin females for 2 h after mating, and only 23% of the tested males mated again within 24h. Together, these results suggested a high paternal investment that may affect reproductive output. To determine if this is the case, and hence if multiple matings affect fecundity andlor longevity, we conducted two oviposition experiments. From these experiments no positive effects on total fecundity or longevity in multiply mated females were apparent.

“…Females of the western tarnished plant bug, Lygus hesperus Knight, are polyandrous, mating repeatedly throughout their lives to ensure a steady supply of sperm and to maintain an elevated rate of oviposition (Strong et al, 1970; Brent, 2010a; Brent and Spurgeon, 2011; Brent et al, 2011). Mating also causes these females to become less attractive than virgins to males (Strong et al, 1970; Brent, 2010a).…”

“…Mating also causes these females to become less attractive than virgins to males (Strong et al, 1970; Brent, 2010a). A sex-pheromone has been identified for this species (Byers et al, 2013), but there is no evidence that the release rate of this chemical blend is affected by the mating status of a female.…”

Passive mechanisms of mate guarding are used by males to promote sperm precedence with little cost, but these tactics can be disadvantageous for their mates and other males. Mated females of the plant bug Lygus hesperus are rendered temporarily unattractive by seminal fluids containing myristyl acetate and geranylgeranyl acetate. These antiaphrodisiac pheromones are gradually released from the female’s gonopore, declining until they no longer suppress male courtship. Because starting quantities of these compounds can vary widely, the repellant signal becomes less reliable over time. Evidence was found of a complimentary mechanism that more accurately conveys female mating status. Once inside the female, geranylgeranyl acetate is progressively converted to geranylgeraniol then externalized. Geranylgeraniol counteracts the antiaphrodisiac effect despite having no inherent attractant properties of its own. This is the first evidence for such an anti-antiaphrodisiac pheromone, adding a new element to the communication mechanisms regulating reproductive behaviors.DOI: http://dx.doi.org/10.7554/eLife.24063.001

As a prerequisite to the elucidation of the sex pheromone of the green capsid bug Lygocoris pabulinus (L.), we studied the bug's reproductive development and behaviour. When kept under long‐day conditions (L18:D6) at 25 °C, both males and females start to copulate 4 days after the final moult. Second matings occur in some females, even on consecutive days. The premating period is 10 min on average and copulation lasts 1 to 2 min. At long range, when males are attracted to traps baited with live females, we did not observe a specific calling position of the females. At short range, a characteristic courtship behaviour of the females was not observed either. Males showed a characteristic vibration of the abdomen, which was repeated several times before copulation. This behaviour can be used as a bioassay to test potential sex pheromone compounds.
