Polidori, Carlo Giordani, Irene Wurdack, Mareike Tormos Ferrando, José Asís Pardo, Josep Daniel Schmitt, Thomas 2017 [EN]Females of most aculeate Hymenoptera mate only once and males are therefore under a strong competitive pressure which is expected to favour the evolution of rapid detection of virgin females. In several bee species, the cuticular hydrocarbon (CHC) profile exhibited by virgin females elicits male copulation attempts. However, it is still unknown how widespread this type of sexual communication is within Aculeata. Here, we investigated the use of CHCs as mating cues in the digger wasp Stizus continuus, which belongs to the family (Crabronidae) from within bees arose. In field experiments, unmanipulated, recently emerged virgin female dummies promptly elicit male copulation attempts, whereas 1–4 days old mated females dummies were still attractive but to a much lesser extent. In contrast, old (10–15 days) mated female dummies did not attract males at all. After hexane-washing, attractiveness almost disappeared but could be achieved by adding CHC extracts from virgin females even on hexane-washed old mated females. Thus, the chemical base of recognition of females as appropriate mating partner by males is coded in their CHC profile. application/pdf http://hdl.handle.net/10366/146421 eng Elsevier 24 Ciencias de la vida 2401 Biología Animal (Zoología) Post-mating shift towards longer-chain cuticular hydrocarbons drastically reduces female attractiveness to males in a digger wasp info:eu-repo/semantics/article TEXT Gredos.
