Queen replacement without gerontocracy in the paper wasp Parapolybia indica in temperate Japan
When the original queens were removed artificially or disappeared naturally, younger females (8.7 days old on average, n = 10) became replacement queens, which coincides with a so-called tropical pattern so far known in tropical-zone paper wasps but not in those from temperate-zones.
The Dynamics of Colony Organization in the Primitively Eusocial Wasp Polistes dominulus Christ
Although an individual's rank tended to determine its behavioural profile, the effects of the hierarchy were found to be based on a stepwise arrangement into large hierarchical groups.
Queen succession in the primitively eusocial tropical waspRopalidia marginata (Lep.) (Hymenoptera: Vespidae)
- BiologyJournal of Insect Behavior
It is shown that in 9 of 12 queen-removal experiments where such a behavioral differentiation could be discerned, the individual that became a queen (the potential queen) was a Sitter in 6 cases, a Fighter in 2 cases, and a Forager in only 1 case.
Size and colony cycle in Polistes satan, a Neotropical paper wasp (Hymenoptera Vespidae)
- Biology, Environmental Science
It is suggested that seasonal variation may affect uninseminated females directly reflecting a flexible developmental programme in primitively eusocial wasps.
Reproduction in foundress associations of the social wasp, Polistes carolina: conventions, competition, and skew
The persistence of some aggressive conflict throughout the foundress period suggests that this convention is not absolute, and Reproductive partitioning in early P. carolina colonies may have more to do with enhancing worker production than with conflict over direct fitness.
Alternative Nesting Strategies of Polistine Wasps in a Subtropical Locale
- Environmental Science, BiologyInsects
A new and unique view of the nesting biology of social wasps is provided by comparing and contrasting the phenology of species in two genera, Polistes and Mischocyttarus, in a context that sheds light on the life history and evolution of this group.
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.
Absence of within-colony kin discrimination: foundresses of the social wasp, Polistes carolina, do not prefer their own larvae
Using DNA microsatellite loci, it was able to determine exactly which female was the mother of each larva in eight nests of the social wasp, Polistes carolina, and the absence of nepotism towards closest kin within colonies in this system is likely to promote colony harmony.
Social Structures and Conflict Resolution in Primitively Eusocial Polistes Wasps
The theory of kin selection (Hamilton 1964a, b) explains the evolution of helping behavior among relatives (see Chap. 3), but it also predicts several conflicts among relatives. First, individuals…
Worker mortality and the evolution of castes in the social wasppolistes exclamans

SummaryWorkers of the primitively social wasp,Polistes exclamans, had very short average lifespans, averaging 14 days (S.D.=11, N=497) in 1977, 17 days (S.D.=14, N=503) in 1978 and 14 days (S.D.=10,…

Dominance Hierarchy and Division of Labour in the Social Wasp, Ropalidida Marginata (Lep.)(Hymenoptera: Vespidae)
The presence of a dominance hierarchy among the workers of a Ropalidia marginata colony can be recognised on the basis of pair-wise interactions such that it is the heavier individuals that develop their ovaries and are capable of becoming egg layers.
Temporary Queens in Metapolybia Wasps: Nonreproductive Helpers Without Altruism?
In Metapolybia aztecoides some mated females produce only workers, losing in competition with other similar egg-layers before producing either males or queens, a by-product of mutualism rather than of kin selection or parental manipulation.
Dominance Order in Polistes Wasps
- BiologyPhysiological Zoology
Group organization as the authors vertebrates show it, is wholly lacking among the lower invertebrates; and, among the social insects, for the most part, it is developed along different lines from the customary pattern in vertebrate groups.
Parasitoids, Predators, and Group Size in the Paper Wasp, Polistes Exclamans
The paper wasp Polistes exclamans loses part of its brood to the parasitoids Chalcoela iphitalis (Lepidoptera:Pyralidae) and Elasmus polistis (Hymenoptera:Chalcidoidea:Eulophidae) and loses entire…
Sex Ratios, Parent-Offspring Conflict, and Local Competition for Mates in the Social Wasps Polistes metricus and Polistes variatus
- BiologyThe American Naturalist
The prediction implicit in Fisher's theory that the remaining population will exhibit a female-biased PI ratio bringing the population investment ratio to 1:1 is met and no local competition for mates is inferred to have occurred based on the observation of no inbreeding and viscosity of the female portion of the population.
