Key to the nests of Brazilian Epiponini wasps (Vespidae: Polistinae)
(2003-08-18)
Brazil possesses the richest diversity of Epiponini wasps in the world. However, field identification of genera of these wasps, based on morphological features, is difficult without optical equipment. Therefore, this work ...
The Usefulness of the Sting Apparatus in Phylogenetic Reconstructions in Vespids, with Emphasis on the Epiponini: More Support for the Single Origin of Eusociality in the Vespidae
(Entomological Soc Brasil, 2014-04-01)
This study aimed at testing the utility of characters derived from chitinous structures of the sting apparatus for elucidating relationships among the genera of Epiponini. The characters were obtained from the spiracular ...
Caste Asymmetries in the Neotropical Swarm-Founding Wasp Polybia (Trychothorax) ignobilis (Hymenoptera, Vespidae, Epiponini)
(California State University, 2011-01-01)
Epiponini wasps are dominant in Neotropical regions and represent, in several ways, exceptions for general theories regarding social insects. They are highly eusocial and most species build large and complex nests. These ...
Caste asymmetries in the neotropical Swarm-founding wasp polybia (Trychothorax) ignobilis (Hymenoptera, Vespidae, Epiponini)
(2011-02-14)
Epiponini wasps are dominant in Neotropical regions and represent, in several ways, exceptions for general theories regarding social insects. They are highly eusocial and most species build large and complex nests. These ...
Morphological and physiological caste differences in Synoeca cyanea (Hymenoptera, Vespidae, Epiponini) according to the ontogenetic development of the colonies
(2003-07-08)
Morphological caste differences in different stages of the biological cycle in Synoeca cyanea were not distinct. Females presented a gradual sequence in ovarian development from filamentous ovarioles to well developed ones ...
Phylogenetic analysis of the Neotropical social wasps of the genus Angiopolybia Araujo, 1946 (Hymenoptera, Vespidae, Epiponini)
(2007-03-19)
A morphological cladistic analysis of the Neotropical swarm-founding genus Angiopolybia Araujo is presented. A single cladogram resulted from the analysis, with the following ingroup topology: (A. pallens + A. zischkai) + ...
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 ...
Foraging behavior and colony cycle of agelaia vicina (Hymenoptera: Vespidae; Epiponini)
(2010-04-01)
The neotropical Agelaia vicina has the largest nest built among social wasps, yet little is known about nest construction, growth and structure. In this work, the development of two nests of A. vicina was followed. Studies ...
Morphological caste differences in three species of the Neotropical genus Clypearia (Hymenoptera: Polistinae: Epiponini)
(2010-12-01)
Clypearia is a rare genus of swarm-founding Neotropical wasp whose biology is very little known. Morphological castes differences, condition of ovaries, relative age, and color pattern differences were analyzed in three ...
Environmental factors influencing foraging activity in the social wasp Polybia paulista (Hymenoptera: Vespidae: Epiponini)
(2011-12-01)
Foraging behavior in social wasps is important in the development of the colony and reflects an important ecological interaction between the colony and the environment. Although the social traits of the colony play a role ...
