“…Clear examples of intralocus conflict in haplodiploids are rare, as the study of sexual conflict in haplodiploids has focused more on sex allocation and polyandry (Macke et al 2014, Shuker et al 2009, Beukeboom et al 2009. A notable exception is a study of extreme intralocus sexual conflict in the invasive ant Nylanderia fulva (Eyer et al 2019).…”

In haplodiploids, (1) alleles spend twice as many generations in females as in males, (2) males are never heterozygous and therefore express recessive alleles, and (3) males sire daughters, but no sons. Intralocus sexual conflict therefore operates differently in haplodiploids than in diploids, and shares strong similarities with loci on X (or Z) chromosomes. The common co-occurrence of all three features makes it difficult to pinpoint their respective roles. However, they do not always co-occur in nature, and missing cases can be additionally studied with hypothetical life cycles. We model sexually antagonistic alleles in eight different sex determination systems, and find that arguments (1) and (2) promote invasion and fixation of female-beneficial and male-beneficial alleles, respectively; (2) also improves prospects for polymorphism. Argument (3) harms the invasion prospects of sexually antagonistic alleles (irrespective of which sex benefits), but promotes fixation should invasion nevertheless occur. Disentangling the features helps to evaluate the validity of previous verbal arguments and yields better informed predictions about intralocus sexual conflict under different sex determination systems, including hitherto undiscovered ones.

“…It is thus likely that some of these compounds are involved in the receptivity switch, a hypothesis which still necessitates further investigation. Reported re-mating rates differ among Nasonia species and between different Nasonia strains (Leonard and Boake, 2008;Geuverink et al, 2009). In addition, re-mating appears to increase in strains having been reared in the laboratory over prolonged time (van den Assem and Jachmann, 1999;Burton-Chellew et al, 2007a).…”

The use of chemical cues and signals is essential for communication in insects. Wasps of the genus Nasonia (Hymenoptera, Pteromalidae) are gregarious parasitoids that lay their eggs into puparia of cyclorrhaphous flies. During their life cycle, various kinds of semiochemicals are used: (1) a male abdominal sex pheromone that attracts females and induces site fidelity in males, (2) a female-derived contact sex pheromone eliciting courtship behavior in males, (3) an oral male aphrodisiac eliciting receptivity signaling in females and causing a switch in the females' olfactory preferences, (4) chemicals derived from host habitat and host puparia used in olfactory host finding by female wasps, and (5) chemicals used by females to assess the quality and parasitization status of potential hosts. We review the literature on the chemical ecology of Nasonia spp. following the wasps' life cycle from emergence to oviposition. We depict biosynthetic pathways where available, discuss ecological implications, highlight differences among Nasonia species, summarize insights into their olfactory perception and associative learning abilities, and point out gaps in our understanding of the chemical ecology of these parasitoids to be addressed in future studies.

“…In most parasitoid wasps, including U. rufipes, males do not provide an obvious nuptial gift or paternal care (Godfray 1994). There is an effect of mating on longevity and/or fecundity in a subset of parasitoid wasp studies (King 2002 review;Reumer et al 2007;Santolomazza-Carbone and Pestana 2010), but the effect is not be present in all studies of even a single species, e.g., in N. vitripennis (Geuverink et al 2009;Boulton and Shuker 2015).…”

Mating Status Effects on Sexual Response of Males and Females in the Parasitoid Wasp Urolepis rufipes

Although mate preferences are most commonly examined in females, they are often found in both sexes. In the parasitoid wasp Urolepis rufipes, both female and male mating status affected certain aspects of sexual interactions. Female mating status mattered only in the later stages of mating. Males did not discriminate between virgin and mated females in terms of which they contacted or mounted first. However, once mounted, most virgin females were receptive to copulation, whereas very few mated females were. Whether a male's mating status affected his own sexual response depended on the female's ability to respond and the stage of mating. Examining male behavior toward dead females allowed elimination of the role of female behavior in how males responded. Virgin and mated males are both attracted to dead females as evidenced by their fanning their wings at such females. However, mated males were quicker than virgin males to contact and to mount in an experiment with dead females, whereas there was no such differential response in an experiment with live females. This difference is consistent with greater female sexual responsiveness to virgin males. Male mating status also affected female receptivity to copulate. Once mounted, live virgin females were less likely to become receptive to copulation by mated males than to virgin males, but only in a choice experiment, not in a no-choice experiment.
