Autumnal Helpers of Polistes dominulus Represent a Distinct Behavioural Phenotype

  title={Autumnal Helpers of Polistes dominulus Represent a Distinct Behavioural Phenotype},
  author={Alessandro Cini and Leonardo Dapporto},
Division of labour is a major feature of insect societies. Behavioural differences can be present also during non-colonial stages of the life cycle, when it is difficult to discriminate between distinct behavioural phenotypes and by-products of differences in overall activity levels. We used the social wasp Polistes dominulus to address this issue. In pre-hibernating aggregations some individuals (helpers) perform external tasks by collecting food and providing it to cluster mates. Such helpers… 
Differential Gene Expression and Protein Abundance Evince Ontogenetic Bias toward Castes in a Primitively Eusocial Wasp
hypotheses of 1) larval developmental pathway divergence that can lead to caste bias in adults and 2) nutritional differences as the foundation of the pathway divergence are supported.
Behavioural and neurogenomic responses of host workers to social parasite invasion in a social insect
These results provide the first evidence of early behavioural and neurogenomic responses of host workers toward the presence of an inquiline social parasite in a social insect.
Sight in a Clique, Scent in Society: Plasticity in the Use of Nestmate Recognition Cues Along Colony Development in the Social Wasp Polistes dominula
For the first time in a social insect, the differential use of visual and chemical cues for nestmate recognition in two different phases of colony is shown, which supports the hypothesis of a plastic, reliability-based use of recognition cues in this species according to the different colonial contexts.
Social parasitism and the molecular basis of phenotypic evolution
How comparisons of social parasites and their free-living hosts may provide unique insights into the molecular basis of phenotypic evolution is discussed, and hypotheses on the molecular based of phenotypes in the evolution of social parasitism are defined.


Wasps in the shadow: Looking at the pre-hibernating clusters of Polistes dominulus
The influence of cluster formation and social networks on the main aspects of wasp social behaviour, such as the consequences on kin-assortment (philopatry and tolerance level), variation in chemical recognition, division of labour, and helping behaviour are evaluated.
Prehibernating aggregations of Polistes dominulus: an occasion to study early dominance assessment in social insects
It is demonstrated that in a given pair, it is more likely that the dominant wasp in autumn becomes the alpha female in spring after the nest foundation phase occurred, and it is showed that dominant females in clusters have both larger body size and ovaries.
A diapause pathway underlies the gyne phenotype in Polistes wasps, revealing an evolutionary route to caste-containing insect societies
It is shown that two signatures of diapause characterize the development of gyne offspring in Polistes metricus, which challenges the view that workers and gynes represent behavior options equally available to every female offspring and exemplifies how social insect castes can evolve from casteless lineages.
Sociality outside the nest: helpers in pre-hibernating clusters of Polistes dominulus
It is shown that the death of workers and the abandonment of the nest do not imply the end of the social phase in Polistes dominulus, and that many social interactions also occur in pre-hibernating clusters.
Dominance interactions in young adult paper wasp (Polistes dominulus) foundresses: a playlike behavior?
The authors investigated the occurrence of a playlike behavior in young individuals of a paper wasp, finding that dominance behavior in aggregations shares several features with mammalian play fighting.
Post-eclosion sensitivity to social context inPolistes dominulus Christ females (Hymenoptera, Vespidae)
The behavioural and biological data obtained here show that when exposed to the new social environment, females from young colonies were able to lengthen their life span and become gynes.
Reproductive caste determination in eusocial wasps (Hymenoptera: Vespidae).
Correlative and experimental studies indicate that differences in nutrition during larval development are often the basis of pre-imaginal caste determination, which has important implications for the roles of subfertility and manipulation by nest mates in the evolution of eusocial behavior.
Bivoltinism as an Antecedent to Eusociality in the Paper Wasp Genus Polistes
An explanatory framework for caste evolution in the eusocial wasp genus Polistes (Vespidae) is presented and it is shown that this mechanistic framework can reproduce colony-level characteristics of Poliste and that social castes can emerge from solitary regulatory pathways.
The Behavior of Hibernating Polistes Wasps.

I make only a meagre offering, for I can throw light on the habits of only one species of Polistes, P. annularis, and give some incomplete notes on a few other species, which, however, show certain tendencies.
Polistes paper wasps : emergence of a model genus
This special issue is the product of a second conference, held at the Tufts University European Center at Taillores, France in spring 2005, and aims to position Polistes wasps as a model genus within the biological sciences.
