Journal ArticleDOI
Conserved class of queen pheromones stops social insect workers from reproducing.
Annette Van Oystaeyen,Ricardo Caliari Oliveira,Luke Holman,Jelle S. van Zweden,Carmen Romero,Cintia Akemi Oi,Patrizia d'Ettorre,Mohammadreza Khalesi,Johan Billen,Felix L. Wäckers,Jocelyn G. Millar,Tom Wenseleers +11 more
TL;DR: The results show that queen pheromones are strikingly conserved across at least three independent origins of eusociality, with wasps, ants, and some bees all appearing to use nonvolatile, saturated hydrocarbons to advertise fecundity and/or suppress worker reproduction.
Journal ArticleDOI
The origin and evolution of social insect queen pheromones: Novel hypotheses and outstanding problems
Cintia Akemi Oi,Jelle S. van Zweden,Ricardo Caliari Oliveira,Annette Van Oystaeyen,Fabio S. Nascimento,Tom Wenseleers +5 more
TL;DR: It is provided compelling evidence that these pheromones should best be seen as honest signals of fertility as opposed to suppressive agents that chemically sterilize the workers against their own best interests.
Journal ArticleDOI
Fifteen shades of green: The evolution of Bufotes toads revisited.

TL;DR: Across the radiation of Palearctic green toads, a stepwise progression of reproductive isolation through time is pinpointed, with a threshold below which hybridizability is irrespective of divergence, above which species barely admix and eventually evolve different mating calls, or can successfully cross-breed through allopolyploidization.
Journal ArticleDOI
Dual Effect of Wasp Queen Pheromone in Regulating Insect Sociality
Cintia Akemi Oi,Annette Van Oystaeyen,Ricardo Caliari Oliveira,Jocelyn G. Millar,Kevin J. Verstrepen,Jelle S. van Zweden,Tom Wenseleers +6 more
TL;DR: It is shown that in the common wasp, Vespula vulgaris, the pheromone that signals egg maternity and enables the workers to selectively destroy worker-laid eggs is in fact the same as one of the sterility-inducing queen signals that was identified earlier.
Journal ArticleDOI
The origin and evolution of queen and fertility signals in Corbiculate bees
Ricardo Caliari Oliveira,Cintia Akemi Oi,Mauricio Meirelles Castro do Nascimento,Ayrton Vollet-Neto,Denise A. Alves,Maria Lúcia C. Campos,Fabio S. Nascimento,Tom Wenseleers +7 more
TL;DR: A phylogenetic analysis of fertility-linked compounds across 16 species of solitary and eusocial bee species suggests that queen signals in Corbiculate bees are likely derived from ancestral fertility- linked compounds present in solitary bees that lacked reproductive castes.
