The European paper wasp Polistes dominula has invaded many parts of the globe and often displaces similar native species. Factors contributing to this remain unclear but may include longer seasonal activity period, natural enemy release, greater colony productivity and smaller body size. Since its discovery in South Africa in 2008, the local abundance of P. dominula has increased greatly. In invaded habitats, it is now much more common than the native P. marginalis. Here we determine some of… 
Nesting Ecology and Colony Survival of Two Invasive Polistes Wasps (Hymenoptera: Vespidae) in New Zealand
Findings of this research suggest that P. dominula will not pose a threat to species inhabiting forested areas, and biodiversity managers should focus their efforts on suburban and coastal environments as native species in these areas will require the greatest protection.
Bioclimatic Modelling Identifies Suitable Habitat for the Establishment of the Invasive European Paper Wasp (Hymenoptera: Vespidae) across the Southern Hemisphere
Two models were created to investigate the potential range expansion of Polistes dominula Christ (Hymenoptera: Vespidae) in the southern hemisphere and found significant range expansion by P. dominula is possible across its more southern invaded ranges.
Invasive paper wasps have strong cascading effects on the host plant of monarch butterflies
This study demonstrates a strong trophic cascade initiated by an invasive predator, the recent arrival of the invasive paper wasp Polistes dominula Christ, associated with substantial declines in local butterfly abundance in New Zealand.
The native and exotic prey community of two invasive paper wasps (Hymenoptera: Vespidae) in New Zealand as determined by DNA barcoding
Social wasps are invasive in many regions around the world. In their new communities, introduced predators such as these wasps may be beneficial as consumers of exotic pests, but they will also
A Potential Role for Phenotypic Plasticity in Invasions and Declines of Social Insects
This review explores the relationship between phenotypic plasticity, invasion biology, and vulnerability to global change in social insects and suggests ways in which considerations of phenotyping plasticity may help in managing social insect populations.


Genetics, behavior and ecology of a paper wasp invasion : Polistes dominulus in North America
A review of this ongoing invasion of the European paper wasp Polistes dominulus into North America in terms of population genetic variation in P. dominulus, and data from comparative studies where the two species are sympatric and possible mechanisms contributing to the differences between them is reviewed.
The comparative biology of two sympatric paper wasps in Michigan, the native Polistes fuscatus and the invasive Polistes dominulus (Hymenoptera, Vespidae)
The biology of the invasive Polistes dominulus and the native P. fuscatus was compared at a field site in Rochester, Michigan over a two-year period and found that P. dominulus is likely replacing P.fuscatus in many areas of southeastern Michigan via indirect or exploitative competition.
A ten-year comparative study of the population dynamics and parasitoidism in the native paper wasp Polistes fuscatus and the invasive P.dominulus
Historical evidence indicates that the parasitoid, D. cavus, is a major factor in stabilizing the populations of the sympatric P. dominulus and P. fuscatus, and the historical pattern of decreasing displacement of P. domulus corresponded temporally with a significant decline in the productivity and a significant increase in Dibrachys cavus infestation.
Extreme Polygyny: Multi-seasonal “Hypergynous” Nesting in the Introduced Paper Wasp Polistes dominulus
Genetic and morphological data indicate the presence of multiple reproductively active females of varying relatedness, as well as many nonbreeding females, including probable early-produced offspring in one spring colony from Los Angeles, California, USA.
The comparative biology of two sympatric paper wasps, the native Polistes fuscatus and the invasive Polistes dominulus (Hymenoptera, Vespidae)
Polistes dominulus (Christ), an old world paper wasp, was introduced accidentally into the eastern coast of the United States in the late 1970s and has been rapidly spreading westward, displacing the native P. fuscatus (F.) through exploitative competition.
Rapid Range Expansion of the Invasive Wasp Polistes dominula (Hymenoptera: Vespidae: Polistinae) and First Record of Parasitoids on this Species and the Native Polistes marginalis in the Western Cape Province of South Africa
Biological control initiatives are largely geared to reconnect IAS with their natural predators and parasites, but this necessitates the release of yet another alien organism.
Displacement and replacement in real time: Polistes dominula’s impact on P. fuscatus in the northeastern U.S.
This system provides an example of a possible extinction vortex caused by competitive exclusion of a species by its invasive congener, in which the invasive wasp drives population declines in the native that in turn allow P. dominula to further establish.
The cost of flight: a role in the Polistes dominulus invasion
In comparing the species, it was found that P. dominulus had a lower absolute flight metabolic rate, but thatP.
Is invasion success explained by the enemy release hypothesis
Given the complexity of processes that underlie biological invasions, it is argued against a simple relationship between enemy ‘release’ and the vigour, abundance or impact of NIS.
First detailed report of brood parasitoidism in the invasive population of the paper wasp Polistes dominulus (Hymenoptera, Vespidae) in North America
This work presents the first well documented case of parasitoidism of the invasive population of P.dominulus in North America and concludes that this population is benefiting from a post-invasion release from enemies.
