“…To date these examples remain limited to intra-specific studies in invertebrates like southern stink bugs ( Nezara viridula ) in which females that mate repeatedly live three or more times longer than females that mate only once or twice [64]. Although we did not detect any positive relationship between polyandry and female mortality across our sample of mammalian species, it is possible that polyandry reduces female survival in some species and increases it in others, which could potentially explain our results.…”

In several taxonomic groups, females mate with several males during a single reproductive cycle. Although there is evidence that polyandry provides some benefits to females, it often involves mortality costs. However, empirical evidences of mortality costs of polyandry have so far been reported only in invertebrates. Whether polyandry has mortality costs in vertebrates is currently unknown. In the present study, we aimed to fill the gap by investigating the relationships between the level of polyandry (measured either by male relative testes mass or the percentage of multiple paternities) and female patterns of mortality across mammals. While we found that the two metrics of female mortality co-varied with pace of life, we did not find any evidence that polyandry leads to either decreased median lifespan or increased aging rate in mammals. We discuss such an absence of detectable mortality costs of polyandry in female mammals in light of recent advances in the study of mammalian reproductive biology and life-history tactics.

“…This is generally not an issue when mass-releasing sterile adult Diptera or Lepidoptera as the larva is usually the damaging life-stage [ 50 ]. Multiple mating by wild female pentatomids [ 51 ] is an important consideration for the success of SIT because they could mate with both sterile and wild males [ 52 ], and it could also stimulate an increase in fecundity [ 53 ]. However, if a suitable overflooding ratio of sterile males is defined and maintained, this should not negatively impact the success of SIT [ 22 , 52 ].…”

Nezara viridula Linnaeus (Hemiptera: Pentatomidae) is a polyphagous pest of a wide range of economically important crops. Because the control of this species and other pentatomids relies primarily on insecticide application, investigation into the Sterile Insect Technique (SIT) is warranted. We aimed to investigate the irradiation biology of N. viridula for the potential application of SIT against this pest. Male and female N. viridula were gamma-irradiated at doses between 4 and 28 Gy and mated with both irradiated and nonirradiated conspecifics. Sterility of the resulting eggs followed a dose-response in each case. Irradiated males crossed with untreated females showed higher F1 egg sterility than crosses where the female was irradiated. The greatest F1 egg sterility was observed when both parents were irradiated. There was no obvious dose-response for the longevity of irradiated males, and for the fecundity of nonirradiated females mated with irradiated males. The fecundity of irradiated females appeared to decrease with irradiation dose. These results can be applied to a potential future application of SIT against N. viridula, but predominantly supports the ongoing development of SIT for Halyomorpha halys Stål (Hemiptera: Pentatomidae) and hemipteran pests in general.

“…Pentatomids are good systems for studies on sexual selection and evolution of genitalia for numerous reasons. Generations are relatively short, copula and oviposition occur at high frequencies, and they have a wide variety of sexual behaviours (Wang & Millar, ; Zahn et al ., ; Silva & Panizzi, ; Fortes & Consoli, ). Most importantly, males and females are promiscuous and both have internal and external genitalia composed by various components that may foster interesting ecological and evolutionary questions.…”

Rapid differentiation and asynchronous coevolution of male and female genitalia in stink bugs

Despite claims that genitalia are among the fastest evolving phenotypes, few studies have tested this trend in a quantitative and phylogenetic framework. In systems where male and female genitalia coevolve, there is a growing effort to explore qualitative patterns of evolution and their underlying mechanisms, but the temporal aspect remains overlooked. An intriguing question is how fast male and female genitalia may change in a coevolutionary scenario. Here, we apply a series of comparative phylogenetic analyses to reveal a scenario of correlated evolution and to investigate how fast male and female external, nonhomologous and functionally integrated genitalia change in a group of stink bugs. We report three findings: the female gonocoxite 8 and the male pygophore showed a clear pattern of correlated evolution, both genitalia were estimated to evolve much faster than nongenital traits, and rates of evolution of the male genitalia were twice as fast as the female genitalia. Our results corroborate the widely held view that male genitalia evolve fast and add to the scarce evidence for rapidly evolving female genitalia. Different rates of evolution exhibited by males and females suggest either distinct forms or strengths of selection, despite their tight functional integration and coevolution. The morphological characteristics of this coevolutionary trend are more consistent with a cooperative adjustment of the genitalia, suggesting a scenario of female choice, morphological accommodation, lock-and-key or some combination of the three.
