Evolution of Caste in Neotropical Swarm-Founding Wasps(Hymenoptera: Vespidae; Epiponini)
This sequence is consistent with Wheeler's theory of the origin of caste through developmental switches, and represents the most thorough test of that theory to date.
Agelaia vicina, a Swarm-Founding Polistine with the Largest Colony Size among Wasps and Bees (Hymenoptera: Vespidae)
The nest size and colony size of A. vicina is evidently unrivalled among all wasps and bees.
Diversity of social wasps (Hymenoptera, Vespidae, Polistinae) in three fragments of semideciduous seasonal forest in the northwest of São Paulo State, Brazil
This work was a survey of social wasps in three areas in different stages of regeneration in Sao Paulo State, where Neves Paulista had the greatest diversity, and Paulo de Faria presented greater abundance.
A Phylogenetic Analysis of Synoeca de Saussure, 1852, A Neotropical Genus of Social Wasps (Hymenoptera: Vespidae: Epiponini)
Abstract Characters of adult morphology, male genitalia, and nest architecture are combined in a cladistic analysis of the neotropical paper wasp genus Synoeca. The single resulting cladogram
Taxonomic diversity, niche width and similarity in the use of plant resources by bees (Hymenoptera: Anthophila) in a cerrado area
Most of the studies on the bee fauna of cerrado have shown incomplete approaches, focusing on species diversity or on a fraction of the assemblage. This work presents similarities among bee species
Diversity of Social Wasps on Semideciduous Seasonal Forest Fragments with Different Surrounding Matrix in Brazil
It was concluded that, with data, a relation between the occurrence of social wasps and the surrounding matrix was not detected and the greatest Shannon-Wiener index of diversity was obtained in Magda.
Phylogenetic Analysis of The Neotropical Pseudopolybia De Saussure, 1863, with Description of The Male Genitalia of Pseudopolybia Vespiceps (Hymenoptera: Vespidae, Epiponini)
Characters of the male genitalia are combined with morphological characters of the females and nests and used in a phylogenetic analysis and the single cladogram resulting supports monophyly of the genus Pseudopolybia and interrelationships among the species.
“Winter” aggregations, colony cycle, and seasonal phenotypic change in the paper wasp Polistes versicolor in subtropical Brazil
This study shows that in the paper wasp, Polistes versicolor, a subtropical species, body size increases as an unfavorable season approaches, and morphological studies indicate that larger females come from winter aggregations—that is, they are new queens.
Caste Flexibility and Variation according to the Colony Cycle in the Swarm-founding Wasp, Parachartergus fraternus (Gribodo) (Hymenoptera: Vespidae: Epiponini)
Findings support the occurrence of caste totipotency in Parachartergus fraternus, which is evidently post-imaginally determined and probably taking place according to the colony conditions.
