“…As in other species (Boomsma & Sundström, 1998; Awad et al. , 2015), the observed uneven SHB paternity might constitute one of the costs of mating for males, but there are no data yet on sperm competition and whether males can adjust the amount of sperm transferred, such as based on mating status or quality of a female or a number of rival males present (Wedell et al. , 2002; Joyce et al.…”

“…Nevertheless, multiple matings are a widespread phenomenon in insects (Ridely, 1988) and have been observed in several invasive species such as ladybugs, Harmonia axyridis (Coleoptera: Coccinellinae), grain beetles, Tenebrio molitor (Coleoptera: Tenebrionidae), red flour beetles, Tribolium castaneum (Coleoptera: Tenebrionidae) (Worden & Parker, 2001; Awad et al. , 2015; Rafter et al. , 2017).…”

“…There are number of costs associated with multiple matings, such as increased risk of injury and predation, as well as disease transmission (Chapman et al, 1995;Westendorp & Kirkwood, 1998;Arnqvist & Nilsson, 2000;Crudgington & Siva-Jothy, 2000;Kawagoe et al, 2001). Nevertheless, multiple matings are a widespread phenomenon in insects (Ridely, 1988) and have been observed in several invasive species such as ladybugs, Harmonia axyridis (Coleoptera: Coccinellinae), grain beetles, Tenebrio molitor (Coleoptera: Tenebrionidae), red flour beetles, Tribolium castaneum (Coleoptera: Tenebrionidae) (Worden & Parker, 2001;Awad et al, 2015;Rafter et al, 2017). For instance, multiple matings by females may facilitate invasions by protecting against the effects of inbreeding depression (Cornell & Tregenza, 2007) or by reducing costs of mating with incompatible or infertile males (Watson, 1991).…”

Multiple mating by both sexes in an invasive insect species, Aethina tumida (Coleoptera: Nitidulidae)

Multiple mating by both sexes is common among sexually reproducing animals. Small hive beetles (SHB), Aethina tumida, are parasites of bee nests endemic to sub-Saharan Africa and have become a widespread invasive species. Despite the considerable economic damages they can cause, their basic biology remains poorly understood.Here we show that male and female small hive beetles can mate multiple times, suggesting that costs for mating are low in this species. In an invasive A. tumida population in the United States, a combination of laboratory experiments for males and paternity analysis with eight polymorphic DNA microsatellite markers for field-caught females were used to estimate the number of mating by both sexes. The data show that females and males can mate multiple times-females mated with up to eight males, whereas males mated with at least seven females. The results also showed that A. tumida displayed a skewed paternity, although this was not consistent among the tested females. Thus, first or last male advantage seem to be unlikely in A. tumida. Our observations that individuals of both sexes of A. tumida can mate multiple times opens new research avenues for examining drivers of multiple mating and determining the role it may play in promoting biological invasions.

“…Multiples studies have focused on the striking warning signal polymorphism observed in some ladybeetles (family Coccinnelidae). For instance, Osawa and Nishida (1992) and Awad et al (2015) showed that polymorphism in the elytra coloration of Harmonia axyridis is maintained either by seasonal mating variation or assortative mating (respectively; Osawa and Nishida, 1992;Awad et al, 2015). In Adalia bipunctata, in contrast, the polymorphism is maintained by assortative mating coupled with inheritance of female preference (Majerus et al, 1982), showing negative frequency-dependent mating selection (i.e., females prefer the rare morph; O'Donald and Majerus, 1984).…”

Multimodal Aposematic Signals and Their Emerging Role in Mate Attraction

et al. 2018

Chemically defended animals often display conspicuous color patterns that predators learn to associate with their unprofitability and subsequently avoid. Such animals (i.e., aposematic), deter predators by stimulating their visual and chemical sensory channels. Hence, aposematism is considered to be "multimodal." The evolution of warning signals (and to a lesser degree their accompanying chemical defenses) is fundamentally linked to natural selection by predators. Lately, however, increasing evidence also points to a role of sexual selection shaping warning signal evolution. One of the species in which this has been shown is the wood tiger moth, Arctia plantaginis, which we here put forward as a promising model to investigate multimodality in aposematic and sexual signaling. A. plantaginis is an aposematic diurnal moth which exhibits sexually dimorphic coloration as well as sex-limited polymorphism in part of its range. The anti-predator function of its coloration and, more recently, its chemical defenses (even when experimentally decoupled from the visual signals), has been well-demonstrated. Interestingly, recent studies have revealed differences between the two male morphs in mating success, suggesting a role of coloration in mate choice or attraction, and providing a possible explanation for its sexual dimorphism in coloration. Here, we: (1) review the lines of evidence showing the role of predation pressure and sexual selection in the evolution of multimodal aposematic signals in general, and in the wood tiger moth in particular;(2) establish gaps in current research linking sexual selection and predation as selective pressures on aposematic signals by reviewing a sample of the literature published in the last 30 years; (3) highlight the need of identifying suitable systems to address simultaneously the effect of natural and sexual selection on multimodal aposematic signals; and (4) propose directions for future research to test how aposematic signals can evolve under natural and sexual selection.

“…While warning coloration has been generally studied as an antipredator strategy (Poulton 1890;Ruxton et al 2004), it can also be under sexual selection via intra-sexual competition or female choice (Summers et al 1999;Jiggins et al 2001;Crothers et al 2011;Crothers and Cummings 2013;Cummings and Crothers 2013;Rojas et al 2018). Ladybird beetles, Harmonia axyridis, have been shown to maintain polymorphism in the elytra coloration by either seasonal mating variation (Osawa and Nishida 1992) or assortative mating (Awad et al 2015) whereas wing coloration in Heliconius butterflies has been shaped by sexual selection via mate choice and assortative mating (Jiggins et al 2001;Merrill et al 2014;Finkbeiner et al 2014). In anurans, Oophaga pumilio females have been shown to choose males based on their coloration Cummings 2008, 2009), and males seem to behave differently depending on their own colors; males from more conspicuous populations are more active (Pröhl and Ostrowski 2011), vocalize from more exposed sites (Rudh et al 2011), and tend to be more aggressive and explorative (Rudh et al 2013) than their duller counterparts.…”

Territoriality and parental care are complex reproductive behaviors found in many taxa from insects to mammals. Parental care can be carried out by the female, the male, or both, depending on the species. Territoriality, in contrast, is predominantly displayed by males. Different selective pressures imposed on individuals from the sex performing territorial or parental care behaviors may also lead to sexual differentiation in other life-history traits. Due to their territorial behavior and their diversity of parental care behaviors, Neotropical poison frogs are an excellent study system to investigate whether behavioral traits can influence sexual differentiation in intrinsic or extrinsic traits of individuals. Here, we evaluate whether territorial and parental care behaviors mediate sexual differentiation in ecological (habitat use) and phenotypic (coloration, morphology) traits in the critically endangered Lehmann’s poison frog (Oophaga lehmanni), a species in which males defend territories while females provide parental care. We found sex differences in habitat use and morphological traits, but not in coloration. Males use trunks and green leaves as perches more frequently and are found on higher substrates, than females. We found no sex differences in body size, but females have longer arms than males, which is probably associated with their parental duties (climbing trees to feed the tadpoles). Altogether, our results provide evidence that selection pressures act differently on male and female traits, and that territoriality and parental care may promote the evolution of sexual differentiation in dendrobatids. Long-term wildlife observations are essential to identify important life-history traits and to evaluate hypotheses about the behavioral ecology and conservation of this and other vertebrate species.
