Colonies ofBelonogaster petiolata in Gauteng (South Africa) produced reproductive offspring (gynes and males) in late January and early February of each nesting season; their appearance was associated with a decline in worker and brood numbers. Brood decline could commence in the presence of a dominant, reproductively active queen, and loss or removal of the queen was not followed directly by cessation of nest growth and brood care. An older worker usually took over the α-position in queenless… 

Dominance behaviour and division of labour in the tropical primitively eusocial wasp Ropalidia cyathiformis

It is suggested that while queen (along with PQ) regulates reproductive division of labour, dominance behavior is not used to regulate the non-reproductive activities of the workers such as bringing food and feeding the larvae; these are self-regulated by individual workers by themselves.

Effect of Larval Topical Application of Juvenile Hormone on Caste Determination in the Independent-Founding Eusocial Wasp Mischocyttarus consimilis (Hymenoptera: Vespidae)

Analyzing morphometric and behavioral data, it is demonstrated experimentally that females emerging from larvae that were treated with JH in the third instar had a significantly larger body size, spent more time in the nest, and were subject to less physical aggression from nestmates compared with Females emerging from untreated control larvae.

Dominance based reproductive queue in the primitively eusocial wasp, Ropalidia cyathiformis

These results suggest that these two sister species have evolved two rather different mechanisms of reproductive caste differentiation, and that neither of them strictly conform either to the so-called “temperate” or “tropical” patterns of queen succession seen in most other species studied so far.

STUDIES ON THE BIOLOGY OF BELONOGASTER (HYMENOPTERA VESPIDAE)

Morphological parameters, such as divergence of the alveolar axes, the lack of displacement in the transverse sections and its limited use in longitudinal sections, explain the «hammock-shaped» form of the nest and its limit of development, reached when the more peripheral cells present a horizontal—or nearly horizontal—position.

POLYGYNY AND THE EVOLUTION OF SOCIAL BEHAVIOR IN WASPS

A "polyg ynous family hypothesis" is proposed as an alternative to the "subsocial" and "semisocial" hypotheses for the evolution of insect sociality.

The Insect Societies

The author wished to relate the three phases of research on insects and to express insect sociology as population biology in this detailed survey of knowledge of insect societies.

Influence d'une difference dans les conditions de temperature et de durée du jour sur le déroulement de la vie de la société chezPolistes dominulus Christ (Hymenoptera: Vespidae) élevé au laboratoire

The development of colonies in the paper wasp,Polistes dominulus, was studied in two experimental situations: in the first, the temperature and the daytime were progressively increased and in the second, these two factors were progressively decreased (situation B: 6 colonies).
