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 Sao Paulo State has generated enormous fragmentation of that forest. Such disturbance has reduced the populations of insects in general. This workExpand

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 cladogramExpand

Agelaia vicina, a Swarm-Founding Polistine with the Largest Colony Size among Wasps and Bees (Hymenoptera: Vespidae)
-Since von Ihering (1903, 1904), Agelaia vicina is famous for its huge nests, but no detailed account has been published. Several nests examined by us were mainly built in shelters but some were halfExpand

“Winter” aggregations, colony cycle, and seasonal phenotypic change in the paper wasp Polistes versicolor in subtropical Brazil
Social wasps from temperate zones have clear annual colony cycles, and the young queens hibernate during winter. In the subtropics, the only previously reported evidence for the existence ofExpand

Phylogenetic Analysis of The Neotropical Pseudopolybia De Saussure, 1863, with Description of The Male Genitalia of Pseudopolybia Vespiceps (Hymenoptera: Vespidae, Epiponini)
Abstract The male genitalia of Pseudopolybia vespiceps are described and compared to congeners. Characters of the male genitalia are combined with morphological characters of the females and nestsExpand

Increasing caste differences related to life cycle progression in some neotropical swarm-founding polygynic polistine wasps (Hymenoptera Vespidae Epiponini)
Morphological analyses of female wasps collected at different points in the development of the colonial life cycle showed that in Polybia occidentalis, P. paulista and P. scutellaris, casteExpand

Caste Flexibility and Variation according to the Colony Cycle in the Swarm-founding Wasp, Parachartergus fraternus (Gribodo) (Hymenoptera: Vespidae: Epiponini)
Abstract 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 developmentExpand

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 speciesExpand
