Morphological caste differences in the neotropical swarm-founding polistinae wasps: Agelaia m. a. multipicta and a. p. pallipes (hymenoptera vespidae)
(1997-10-01)
Distinct size dimorphism was found between queens (inseminated egglayers) and workers (uninseminated non egg-layers) sampled from mature colonies of Agelaia pallipes and A. A. multipicta. In both species, among 22 measured ...

Diversity of social wasps (Hymenoptera. Vespidae, Polistinae) in three fragments of semideciduous seasonal forest in the northwest of São Paulo State, Brazil. Human exploitation of the forest in the northwest of São Paulo ...
Morphological studies on castes of Protopolybia chartergoides (Hymenoptera, Vespidae, Epiponini) observed in colonies during male production stage
(Sociedade Brasileira de Entomologia, 2007-12-01)
Vespas sociais são importantes para o estudo da evolução do comportamento social devido suas colônias apresentarem diferentes graus de diferenciação de castas, de morfologicamente similares às altamente conspícuas, associadas ...
Muscles-bearing of sting apparatus in social wasps and their relationship with the autotomy (Hymenoptera: Vespidae: Polistinae)
(Assn Advan Zoology, 1997-06-01)
The musculature that sustains the stinging organ was studied in three species of social wasps using scanning electron microscopy technique. It were observed some differences among species in which sting autotomy occurs and ...

Survey of social wasps (Hymenoptera, Vespidae, Polistinae) in Amazon rainforest fragments in Acre, Brazil
(Inst Nacional Pesquisas Amazonia, 2018-04-01)
The State of Acre, in the southwestern Brazilian Amazon, harbors high biodiversity and a high degree of endemisms. Nevertheless, there are few studies on the diversity of social wasps occurring in this region. This study ...
Temporal polyethism and survivorship of workers of Agelaia pallipes (Hymenoptera, Vespidae, Epiponini)
(2005-04-18)
In this study, known-age workers of Agelaia pallipes (Olivier) were introduced into a colony maintained in the laboratory and the effects of age polyethism on the worker life span were observed. As in other Neotropical ...
Caste flexibility and variation according to the colony cycle in the swarm-founding wasp, Parachartergus fraternus (Gribodo) (Hymenoptera : Vespidae : Epiponini)
(Kansas Entomological Soc, 2004-10-01)
Differences between castes and related aspects in Parachartegus fraternus (Gribodo) have been studied in various stages of the colony cycle. Five colonies from three colony development stages (namely, pre-emergence, ...
Regulation of Social Hierarchy Over Time in Colonies of the Primitive Eusocial Wasp Mischocyttarus (Monocyttarus) cassununga. Von Ihering, 1903 (Hymenoptera, Vespidae)
(Kansas Entomological Soc, 2010-04-01)
Dominance behaviours among members of colonies of primitively eusocial wasps establish the social hierarchy, and are very important for the maintenance of social stability. The present work aimed at the factors involved ...
