“…Many closely related species differ in the signals involved in sexual communication and mate recognition (Byrne, 1999;Isoherranen et al, 1999;Rafferty & Boughman, 2006;Secondi et al, 2010;Gleason et al, 2012;Giglio & Dyer, 2013;Weiss et al, 2015).

Closely related species often differ in the signals involved in sexual communication and mate recognition. Determining the factors influencing signal quality (i.e. signal's content and conspicuousness) provides an important insight into the potential pathways by which these interspecific differences evolve. Host specificity could bias the direction of the evolution of sexual communication and the mate recognition system, favouring sensory channels that work best in the different host conditions. In this study, we focus on the cactophilic sibling species Drosophila buzzatii and D. koepferae that have diverged not only in the sensory channel used for sexual communication and mate recognition but also in the cactus species that use as primary hosts. We evaluate the role of the developmental environment in generating courtship song variation using an isofemale line design. Our results show that host environment during development induces changes in the courtship song of D. koepferae males, but not in D. buzzatii males. Moreover, we report for the first time that host rearing environment affects the conspicuousness of courtship song (i.e. song volume). Our results are mainly discussed in the context of the sensory drive hypothesis.

“…Males of Anomophotopsis quinteroi CAMBRA and Pseudomethoca melanocephala melanocephala (PERTY) were attracted to and attempted to mate only with females of their own species (Garcia et al 2006). Most studies of airborne chemical pheromones have focused on a single species (but see Weiss et al 2015); therefore, it is unclear whether non-species-specific female pheromones are common in other hymenoptera (Godfray & Cook 1997;Ayasse et al 2001).…”

“…Linsley et al (1955) proposed that males primarily use visual cues, based on the observation that males approached "worn" (i.e., non-virgin) females as frequently as newly emerged females. However, other studies proposed the idea that males locate receptive females by detecting female-released sex pheromones, as is common in other hymenoptera (Ferguson 1962;Manley 1977;Ayasse et al 2001;Keeling et al 2004;Weiss et al 2015).…”

Is love in the air or at first sight? Mate finding cues used by sympatric male velvet ants (Hymenoptera: Mutillidae)

Mate finding has been examined in a wide range of hymenopteran families, with the greatest knowledge from social species and parasitoids used in pest management. Velvet ants (Hymenoptera: Mutillidae) provide a unique system to study mate finding because short‐lived flying males must find solitary, wingless females that have spatially and temporally dispersed emergence. Based on limited field observations, it is thought that male velvet ants may use visual, chemical, and vibratory cues for mate finding, though there have been no controlled experiments to test these hypotheses. Using choice experiments, this study aims to determine the role of visual and airborne chemical cues used in female detection by three sympatric species of Dasymutilla males. We find that visual cues are not used for initial female detection and that airborne chemicals are sufficient for female detection. We also discover that males readily approach females of different species, indicating airborne chemicals are not used for species recognition. Despite the lack of discrimination by males, we determined that the sympatric, morphologically similar species show no genetic introgression, and therefore some other isolating mechanism must be at play after males make initial contact with the females.

“…The males of leaf beetles Pyrrhalta maculicollis and P. aenescens preferentially mate with females bearing conspecific chemical profiles (Zhang et al, 2014). Three species of parasitoid wasps Leptopilina heterotoma, L. boulardi, and L. victoriae use combinations of different chemical cues to identify conspecific mates (Weiss et al, 2015).…”

Chemical cues mediate species recognition in field crickets

et al. 2015

Cuticular hydrocarbons (CHCs) are important in mate choice in many insects, and may be used for species recognition if CHC profiles differ between potentially hybridizing species. In the sibling field cricket species Gryllus campestris and G. bimaculatus, females of G. bimaculatus are tolerant toward G. campestris males and can mate with them. However, G. campestris females are highly aggressive toward heterospecific G. bimaculatus males, and matings between them never happen. We examined whether cricket females might use CHCs to determine the species identity of their potential mates. We firstly analyzed the cuticular chemical profile by gas chromatography and mass spectrometry to assess the potential of CHCs to be used for species recognition in these crickets. We then manipulated females' ability to detect chemical cues by carrying out chemical ablation of the antennae, and measured changes in aggressive responses to heterospecific males. We show that there are significant interspecies differences in CHC expression for both sexes, and that females with chemically ablated antennae reduce aggressive behavior toward heterospecific males. Our findings support the prediction that cuticular semiochemicals can play a key role in reproductive isolation between closely related insect species.
