Altitudinal distribution and body resource allocation in a high mountain social wasp (Hymenoptera: Vespidae).

Social Wasps (hymenoptera: Vespidae) Nesting in Eucalyptus Plantations in Minas Gerais, Brazil

Social wasp colonies can be transferred to agroecosystems in order to control pest populations. Some failures of such transfers are common because wasps may abandon the nest immediately after the colony’s transfer. Knowing the nesting habits of wasps in agroecosystems could improve the success of colony transfer during wasp management. Thus, we recorded social wasp nests in a eucalyptus plantat...

Predation of Zaprinus Indianus (diptera: Drosophilidae) by the Social Wasp Synoeca Cyanea (hymenoptera: Vespidae)

Stenonartonia tekoraava sp. nov. (Hymenoptera: Vespidae: Eumeninae), a new member of a typical Amazonian mimicry ring.

Stenonartonia tekoraava sp. nov., a new species of potter wasp is described from central Amazonia. By size and color pattern, this species falls into the typically Amazonian mimicry ring of the social wasp Polybia liliacea (Fabricius) [Vespidae: Polistinae]. Comments are made on the Müllerian mimicry rings as a common phenomenon in Hymenoptera and particularly in the family Vespidae. 

Diversity and community structure of social wasps (Hymenoptera: Vespidae) in three ecosystems in Itaparica island, Bahia State, Brazil.

We studied the structure and composition of communities of social wasps associated with the three insular ecosystems: mangrove swamp, the Atlantic Rain Forest and the 'restinga'- lowland sandy ecosystems located between the mountain range and the sea. Three hundred and ninety-one nests of 21 social wasp species were collected. The diversity of wasps found in each ecosystem was significantly cor...

Castes in the neotropical social wasp Leipomeles dorsata (Fabricius) (Hymenoptera: Vespidae): a window for workers achieving a new status in the colony.

Morphometric studies performed in several species of Neotropical social wasps from the tribe Epiponini showed that in some species there are marked differences between castes, while other species present highly distinct castes with differences only in ovarian development. This work analyzed females from six colonies of the social wasp Leipomeles dorsata (Fabricius) in which queens (egglayers) a...
