Biological Notes on the Parasitism of Apoica flavissima Van der Vecht (Hymenoptera: Vespidae) by Seminota marginata (Westwood) (Hymenoptera: Trigonalidae): Are Social Paper Wasps Primary or Secundary Hosts of Trigonalidae?

open access: yesSociobiology, 2013
Hosts of Trigonalidae include larvae of social paper wasps, which have been considered secondary hosts, supposedly following predation of the primary host (usually caterpillars) by adult wasps.

Updating the geographic records of social wasps (Vespidae: Polistinae) in Roraima state

open access: yesSociobiology, 2017
The Roraima state in Brazil is part of Northern Amazon, an area harboring high biodiversity and high degree of endemism. Nevertheless, there are few studies on diversity of social wasps occurring in this region. This study presents a list of social wasps

Social wasps (Vespidae: Polistinae) from Ducke Reserve, Amazonas, Brazil

open access: yesSociobiology, 2017
Social wasps are common elements in Neotropics, although even elementary data about this taxon in the Amazon region is partially unknown. Therefore the purpose of this work was to increase the knowledge of social wasp fauna at the Ducke Reserve.

Does Wolbachia infection affect Trichogramma atopovirilia behaviour? [PDF]

open access: yes, 2010
Unisexual Trichogramma forms have attracted much attention due to their potential advantages as biocontrol agents. Fitness studies have been performed and understanding the cost that Wolbachia may inflict on their hosts will help in deciding if Wolbachia

Sight in a Clique, Scent in Society: Plasticity in the Use of Nestmate Recognition Cues Along Colony Development in the Social Wasp Polistes dominula

open access: yesFrontiers in Ecology and Evolution, 2019
Nestmate recognition, i.e., the ability to discriminate nestmates from foreign individuals, is a crucial feature of insect societies, and it has been traditionally considered to be predominantly based on chemical cues. Recent empirical evidence, however,

Demographic History and Population Structure of Polistes fuscatus Paper Wasps [PDF]

open access: yes, 2018
Limited dispersal and cooperation are predicted to coevolve in cooperatively breeding systems. In Polistes paper wasps, mark-recapture studies and genetic analyses have shown that both cooperative and solitary nesting gynes can exhibit natal philopatry.
