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 ...
Social Wasp Diversity (Vespidae, Polistinae) in a Forest Fragment in the Northeast of Sao Paulo State Sampled with Different Methodologies
(CALIFORNIA STATE UNIV, 2010)
Social wasp diversity in Semideciduous Seasonal Forests of the northeast of Sao Paulo State is poorly known, causing a lack of information on the diversity of these wasps from these areas which have been degraded. The ...
Social Wasp Diversity (Vespidae, Polistinae) in a Forest Fragment in the Northeast of São Paulo State Sampled with Different Methodologies
(California State University, 2010-01-01)
Social wasp diversity in Semideciduous Seasonal Forests of the northeast of São Paulo State is poorly known, causing a lack of information on the diversity of these wasps from these areas which have been degraded. The ...
Morphological caste studies in the neotropical swarm-founding polistinae wasp Angiopolybia pattern (Lepeletier) (hymenoptera: Vespidae)
(Entomological Soc Brasil, 2008-11-01)
Neotropical swarm-founding wasps present polygynic colonies and a great variation in relation to caste differentiation, ranging from species in which queens and workers are similar in shape and size to those where variation ...
A survey of DNA methylation across social insect species, life stages, and castes reveals abundant and caste-associated methylation in a primitively social wasp
DNA methylation plays an important role in the epigenetic control of developmental and behavioral plasticity, with connections to the generation of striking phenotypic differences between castes (larger, reproductive queens ...
External Morphology of the Immatures of Polybia paulista (Hymenoptera: Vespidae)
(Florida Entomological Soc, 2012-12-01)
The immatures of Polybia paulista Ihering were described using light and scanning electron microscopy and the results are compared with previous descriptions within the same or related wasps. This study is based on 2 whole ...
Division of labor in stable social hierarchy of the independent-founding wasp Mischocyttarus (Monocyttarus) cassununga, von Ihering (Hymenoptera, Vespidae)
In colonies of independent-founding wasps, social organization is characterized by a division of labor wherein the most dominant female (the queen) spends more time on the nest comb during its development, while the ...
Caste differences in Pseudopolybia compressa (Hymenoptera: Vespidae: Polistinae)
(Sociedade Brasileira de Zoologia, 2009)
Studies of morphological caste syndromes in the tribe Epiponini help us to understand the evolution of social behavior in insects. Few studies have integrated morphological syndromes of various species from the same or ...
Relationship between body size and flying-related structures in Neotropical social wasps (Polistinae, Vespidae, Hymenoptera)
(SPRINGERNEW YORK, 2012)
Body size influences wing shape and associated muscles in flying animals which is a conspicuous phenomenon in insects, given their wide range in body size. Despite the significance of this, to date, no detailed study has ...
Diversity of Polistinae Wasps (Hymenoptera, Vespidae) in Fragments of Atlantic Rain Forest With Different Levels of Regeneration in Southeastern Brazil
(California State UnivChicoEUA, 2010)
