Social parasitism of Polistes dominulus by Polistes nimphus (Hymenoptera, Vespidae)
Insectes Sociaux, 2004Interspecific facultative social parasitism is well known in ants and in bumble-bees, but it is rarer in wasps. This form of parasitism is traditionally considered to be an intermediate stage in the evolution of obligate interspecific parasitism, where the parasites are no longer able to nest alone.

Polistes dominulus (Hymenoptera: Vespidae) larvae possess their own chemical signatures
Journal of Insect Physiology, 2007Social insects use cuticular hydrocarbons (CHCs) as recognition cues in a variety of social contexts, such as species and nestmate recognition. Discrimination of nestmates is an important requisite to avoid exploitation by unrelated individuals. In social wasps, use of CHCs in nestmate recognition has been demonstrated only among adults, whereas very ...

Insectes Sociaux, 2002
We present a method of extracting DNA from medium-sized paper wasps without sacrificing the animal. From the distal half of a single leg, enough DNA is extracted for 125 PCR reactions. This DNA - collected from Polistes dominulus and P. fuscatus– amplifies as well as DNA extracted from larger amounts of tissue taken from sacrificed animals, and the ...

Alternative mating tactics in males of Polistes dominulus (Hymenoptera: Vespidae)
Behavioral Ecology and Sociobiology, 1988In summer, males of Polistes dominulus form large aggregations at sunny landmarks. We identified two size-correlated behavioural categories: residents (R) and transient (T). R males, which constitute 20%–25% of the total population, are larger than T males, territorial, aggressive, and more site-faithful, while T males range more widely, are non ...

Thermoregulation in the primitively eusocial paper wasp, Polistes dominulus
Insectes Sociaux, 2009Regulation of wing muscle temperature is important for sustaining flight in many insects, and has been well studied in honeybees. It has been much less well studied in wasps and has never been demonstrated in Polistes paper wasps. We measured thorax, head, and abdomen temperatures of inactive Polistes dominulus workers as they warmed after transfer ...

Factors influencing the adoption of artificial nests in Polistes dominulus (Christ)
Behavioural Processes, 2001Nest recognition is critical to the sociality of wasps. Studies on Polistes have shown that is essentially based on chemoreception. Moreover, wasps are also able to recognise the nest's contents and this could also participate in nest recognition. By the method of the artificial nest adoption, we examined which natural nest stimuli (hydrocarbons from ...

Larval sex identification in the paper wasp Polistes dominulus (Vespidae, Hymenoptera)
Insectes Sociaux, 2007Identifying the sex of larvae is important in social Hymenoptera. Until now for Polistes wasps it has been necessary to genotype larvae at microsatellite loci, and assign their sex based on homozygosity at these loci. In our study on the paper wasp Polistes dominulus we have found morphological differences between larval sexes that can be used for ...

Autumnal Helpers ofPolistes dominulusRepresent a Distinct Behavioural Phenotype
Annales Zoologici Fennici, 2009Division 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.

Dynamics of colony development in Polistes dominulus : a modeling approach
Behavioral Ecology and Sociobiology, 1996A simple model based on feedback mechanisms is developed to describe the dynamics of brood production and colony development of primitively eusocial paper wasps. The presence of pupae and empty cells stimulate egg laying, which varies between a basic rate and a physiological maximum.
